Archetype Overview

Boros Energy is a low-curve creature deck in which nearly every card makes something else in the list better. You deploy one- and two-drops that create tokens, turn those tokens into energy and life, and convert both into damage. It plays like aggro on a fast draw, but it can grind through a long game, and its interaction is cheap enough that you are rarely forced to choose between developing your board and answering your opponent's threats. This list won the Regional Championship - South America on 2026-10-24 out of 404 players.

The Plan

You win by building a board wider than your opponent can handle and then making that board hurt in more than one way. The early turns look like this:

• Turn one: Ragavan, Nimble Pilferer, Ocelot Pride, or Guide of Souls.
• Turn two: Ajani, Nacatl Pariah or Voice of Victory, each of which puts more than one body into play.
• Payoff: Guide of Souls triggers on every creature entering after it. Each trigger gives you 1 life and 1 energy. Once you have three energy, each attack lets you add two +1/+1 counters and flying to an attacker.

Life gained this way also turns on Ocelot Pride, which makes a Cat token at your end step. With enough permanents for the city's blessing, it also copies each token that entered that turn.

The token makers are what tie the engine together:

• Voice of Victory brings two attacking Warriors every time it swings.
• Seasoned Pyromancer filters your hand and makes Elementals for each nonland card you discard.
• Dalkovan Encampment adds two more attacking Warriors from a land slot.

Every one of those tokens feeds Guide of Souls and Haliya, Guided by Light. Haliya, Guided by Light draws you a card when you gain 3 or more life in a turn, and wide boards hit that number easily.

Why the Plan Is Strong

The synergies overlap without depending on one piece. Ajani, Nacatl Pariah comes with its own Cat Warrior. When any other Cat you control dies, Ajani transforms into a planeswalker. That can happen in combat, to opposing removal, or through Goblin Bombardment. Once flipped, the 0 ability makes another token. It also deals damage equal to your creature count if you control another red permanent. This list has plenty of those:

• Ragavan, Nimble Pilferer
• Seasoned Pyromancer
• Goblin Bombardment
• Blood Moon
• Every red Elemental and Warrior token

As a result, the planeswalker's damage clause is almost always live.

Your removal also builds your engine. Galvanic Discharge gives three energy and lets you spend any amount. If Guide of Souls has already banked energy, it kills larger creatures than its cost suggests. Anything you don't spend stays available for the Angel pump. Static Prison exiles any nonland permanent and gives two energy, which Guide of Souls can keep topping up so the Prison stays in play. Thraben Charm scales with your board. It also doubles as enchantment removal or graveyard hate, so it is rarely a dead card.

Goblin Bombardment is the closer. Mobilize Warriors and Dalkovan Warriors are sacrificed at end step anyway, so you can sacrifice them to Bombardment for free damage first. Cat tokens sacrificed this way flip Ajani. Late in a game, a board of 1/1s becomes direct damage to any target, so your opponent has to deal with your life total, your attackers, and your Bombardment all at once.

Voice of Victory protects your turn. Your opponents can't cast spells during your turn. That cuts off instant-speed removal in combat, counterspells against your plays, and flash blockers. Against interactive decks, sequencing Voice of Victory first lets you deploy the rest of your hand into an empty window.

The mana supports the disruption. The list runs 22 lands, including three basics. Fetches can find Sacred Foundry or the basics, and Elegant Parlor counts as a Mountain for Dalkovan Encampment and Arena of Glory. This lets you run a single main-deck Blood Moon as a surprise threat against greedy mana bases. Your own colors survive it through basics and red-producing lands. Arena of Glory adds haste for a late Seasoned Pyromancer or Haliya, Guided by Light, so you can attack through a stabilized board.

Where It Can Struggle

The deck's strength is going wide with small bodies. That means effects that punish small creatures or a wide board are the main threats:

• Sweepers
• Large blockers that outclass your tokens
• Strategies that ignore combat entirely

Your main-deck answers are cheap and flexible but few in number. Static Prison and Thraben Charm handle problem permanents, and Goblin Bombardment lets you convert creatures to damage in response to a sweeper. You still have to plan which threats you can afford to answer and which you need to race.

Who Should Pick It Up

Play this deck if you like constant small decisions with high stakes:

• When to spend energy and when to bank it
• Which token to sacrifice and when
• Whether to flip Ajani now or hold a Cat back
• Whether to cast Seasoned Pyromancer to dig or save it as a late-game token source from the graveyard

The deck rewards precise combat math and careful counting of triggers. It punishes autopilot, because mis-ordered end-step triggers and wasted energy add up quickly. If you want a proactive deck that still has real interaction, plays at a good tempo, and has a full sideboard of answers for opposing strategies, this is a strong choice.

The estimated cost is about $805. Most of that is concentrated in the mana base and the premium one-drops. If you already own Modern staples, that is a reasonable buy-in for a list that won a 404-player Regional Championship.

Core Strategy & Game Plan

How the Deck Wins

Boros Energy wins by putting more bodies on the battlefield than the opponent can answer one at a time, then turning those bodies into damage from three directions: combat, Goblin Bombardment activations, and Ajani, Nacatl Pariah's planeswalker side. Every creature that enters feeds the engines, and the engines produce more creatures. Your goal is not one big threat. It is a board where removing any single piece barely slows you down.

Posture: Proactive First, Interaction as Tempo

You are the beatdown in almost every game. The eight burn-style removal spells (Galvanic Discharge, Lightning Bolt) plus Thraben Charm and Static Prison are not there to grind card-for-card. They clear the one blocker or engine piece standing between your board and a lethal attack. Spend removal on the creature that stops your plan, not on the first creature you see. Blood Moon is the other kind of interaction. It is a tempo play against decks built on nonbasic lands, and it comes down while you are already ahead on board. Fetch your basic Plains before you cast it so you keep white mana.

The Engine Pieces and How They Interlock

• Guide of Souls is the hub. Every other creature entering gives you 1 life and 1 energy, and tokens count. Ajani, Nacatl Pariah alone puts two creatures onto the battlefield, which means 2 life and 2 energy. On any turn you attack with 3 energy banked, Guide turns an attacker into a flying Angel with two +1/+1 counters.
• Ocelot Pride converts that life gain into cards on board. Any life gained on your turn makes a 1/1 Cat at your end step. The life can come from Guide triggers, Ocelot's own lifelink, or Haliya, Guided by Light. Once you control ten permanents, Ocelot also copies every token that entered that turn. Lands count toward the ten, so the city's blessing arrives earlier than it looks.
• Energy is one shared pool. Galvanic Discharge gives you 3 energy, and you choose how much to spend. Kill a 2-toughness creature with 2 and bank 1 toward the next Guide pump. Guide triggers also top up Discharge, so a later Discharge can hit for more than 3. Static Prison adds 2 energy but costs 1 every turn to keep. Count your pool before committing it to removal, the Angel pump, or Prison upkeep.
• Voice of Victory is both a threat and protection. Each attack creates two red Warrior tokens. Those tokens trigger Guide twice, and the resulting life gain switches on Ocelot. More importantly, opponents can't cast spells during your turn. While Voice is on the battlefield, they cannot respond to your combat, your Bombardment activations, or your Ajani flip with instant-speed spells. Any interaction they want has to happen on their own turn.
• Goblin Bombardment is your reach and your Ajani trigger. Sacrifice the temporary Warrior tokens from Voice of Victory or Dalkovan Encampment for damage before they leave anyway. Sacrifice a Cat, either Ajani's token or an Ocelot token, to flip Ajani on your own schedule. Bombardment is also a red permanent, so it switches on the Avenger's 0 ability. That ability makes a Cat Warrior, then deals damage equal to your creature count to any target, and the new token counts.

At your end step, put Ocelot Pride's trigger on the stack so it resolves while the Mobilize tokens are still on the battlefield. With the city's blessing, Ocelot copies those tokens. The copies were never "them" for the sacrifice instruction, so they stay.

Card Flow

Aggro decks usually run out of gas. This list avoids that with three sources of card flow:

• Ragavan, Nimble Pilferer steals the top card of the opponent's library when it connects.
• Seasoned Pyromancer turns excess lands into fresh cards, plus red Elementals that trigger Guide.
• Haliya, Guided by Light draws a card whenever you gain 3 or more life in a turn. That is easy with Guide out. Ragavan's Treasure tokens are artifacts, so they also trigger Haliya.

When the opponent trades evenly with your early threats, these cards keep you deploying.

The Ideal Game, Turn by Turn

1. Turn 1: Play Guide of Souls or Ocelot Pride, or play Ragavan, Nimble Pilferer if the opponent has no obvious play to block it. Guide is the best opener when your hand holds a two-drop that makes tokens.
2. Turn 2: Cast Ajani, Nacatl Pariah into an existing Guide for 2 life and 2 energy. With Ocelot also out, that life gain makes a Cat at end step. Another strong option is two one-drops together, Guide and Ocelot, which immediately starts the life-to-token loop. Cast Voice of Victory here instead if you expect the opponent to rely on instant-speed answers.
3. Turn 3: Attack, pump with Guide if you have 3 energy, and add pressure. Goblin Bombardment plus a one-drop or Discharge works well. So does Seasoned Pyromancer for refuel, or Haliya, Guided by Light as a sticky 3/3 that keeps cards coming.
4. Turn 4 and beyond: Close the game. Attack with Mobilize tokens, sacrifice them to Bombardment after combat damage, flip Ajani off a Cat sacrifice, and use the Avenger's 0 ability to point creature-count damage at the opponent's face or their last blocker.

When to Change Gears

If the opponent has a sweeper-style plan, stop overextending. Hold one or two creatures back and let Goblin Bombardment and Ajani's token-making regrow your board. Against faster decks, flip roles: Guide and Ocelot lifegain buys time, and removal stops their key threat. Shift back to attacking once their first wave is handled. The deciding question each turn is what single card stops you. If you can answer it, keep attacking. If you can't, build your board so that card isn't enough.

Card Choices & Breakdown

The Cat Package: Ajani, Nacatl Pariah, Ocelot Pride, Guide of Souls

These twelve one- and two-drops are the deck's base, and all three run at four because each one makes the others better.

• Ajani, Nacatl Pariah is two bodies for two mana. The 2/1 Cat Warrior token is the important part. When that token or any other Cat dies, Ajani can flip. Ocelot Pride is a Cat and makes Cat tokens, so trading those in combat or sacrificing them to Goblin Bombardment turns Ajani into a planeswalker. His 0 ability only deals damage if you control another red permanent, and this list has plenty: Ragavan, Nimble Pilferer, Seasoned Pyromancer and its Elementals, the Warriors from Voice of Victory, Goblin Bombardment, and Blood Moon.
• Guide of Souls is the energy battery. Every token from Ajani, Voice, Pyromancer, Ocelot, and Dalkovan Encampment gives you 1 life and one energy. Spend that energy on the Angel attack trigger, or save it for a bigger Galvanic Discharge and to keep Static Prison on the battlefield.
• Ocelot Pride turns that incidental lifegain into a Cat every end step. A 1/1 first striker with lifelink can trigger itself by connecting. Guide and Haliya, Guided by Light trigger it with no combat at all. Once you have ten permanents, the city's blessing copies every token that entered that turn, which wins long games.

Pressure and Card Flow: Ragavan, Nimble Pilferer, Seasoned Pyromancer, Voice of Victory, Haliya, Guided by Light

• Ragavan, Nimble Pilferer (4) is the best turn-one play you can make. Each connection gives you a Treasure and a card from the opponent's deck. Dash lets you redeploy him later in the game, and it lets him dodge sorcery-speed removal.
• Seasoned Pyromancer (4) gives an aggro deck real card selection. It draws two cards even from an empty hand. It turns dead nonland cards into 1/1s, which are fodder for Bombardment and red permanents for Ajani. Once it hits the graveyard, its exile ability is a mana sink for long games.
• Voice of Victory (4) does two jobs. Mobilize 2 adds two attackers every combat, which means two Guide triggers and Bombardment fodder that you were going to sacrifice anyway. Its static ability also stops opponents from casting spells on your turn. That shuts off combat tricks, instant-speed removal on your attack step, and counterspells against your main-phase plays.
• Haliya, Guided by Light (1) is the single legendary top-end slot. Treasures count as artifacts, so Ragavan triggers it too. The draw clause checks when the ability resolves, so put your Ocelot Pride trigger on the stack to resolve first. The Cat token's life point can then push you to three. Warp for {W} lets you cast it early for one turn of lifegain and a card, then cast it again later from exile. One copy is enough because it adds to your engine rather than being the engine.

Removal and Reach

• Galvanic Discharge (4) is the main removal spell. It always deals at least 3 damage. With banked energy from Guide it kills much bigger creatures, and any energy you don't spend stays available for Angel triggers.
• Lightning Bolt (2) is here because it can hit players. Discharge can't, so Bolt is your burn to finish the opponent. It runs at two rather than four because Discharge is usually the better removal spell.
• Thraben Charm (2) gets stronger with your board. Its first mode deals twice your creature count, which handles large threats once you have a few tokens out. The enchantment and graveyard-exile modes give you flexible answers in game one.
• Goblin Bombardment (3) is a sacrifice outlet, a way to finish games, and protection against removal and sweepers all in one card. Sacrificing a Cat token flips Ajani on demand. Sacrificing mobilize tokens before they disappear at end step is free damage. Three copies means you find one reliably. A second copy adds much less than the first, because both draw from the same pool of creatures.

The Hate Slots: Blood Moon and Static Prison

Blood Moon is a single main-deck copy, with another in the sideboard. It punishes manabases built on utility lands. In the window from 2026-10-01 to 2026-10-18, every Broodscale Bloodchief Top 8 list ran Eldrazi Temple and Urza's Saga (source: MTGTop8, 2026-10-01 to 2026-10-18). Your own nonbasics become Mountains too, so fetch your basic Plains before you cast it.

Static Prison is a one-mana exile effect for any nonland permanent, including artifacts and planeswalkers that your damage-based removal can't reach. It gives you two energy upfront. In this deck, Guide and Discharge keep feeding it energy, so the upkeep cost is usually easy to pay.

The Manabase

The deck runs 22 lands, which works for a curve that tops out at three. All eleven fetches find Sacred Foundry and Elegant Parlor because both are Mountain Plains. Every fetch also finds a basic Plains, and Arid Mesa can also find the lone Mountain, so you can get basics when you need them under your own Blood Moon.

• Elegant Parlor (2) enters tapped but surveils.
• Dalkovan Encampment (2) gives you somewhere to spend mana late. Its Warriors trigger Guide, feed Ocelot's lifegain, and fuel Bombardment.
• Arena of Glory (1) gives Seasoned Pyromancer or Voice of Victory haste, so they can attack the turn they come down.

Encampment and Arena both enter untapped as long as you control a Mountain, which includes Foundry or Parlor. Fetch for a Mountain-typed land before you play them.

The Decklist

This is the exact 75 that took 1st Place at the Regional Championship - South America on 2026-10-24, a 404-player field, played by user Luisvenegas. The estimated cost is about $805 at TCGplayer market prices. Notes below mark which slots are fixed and which are open to tuning.

Main Deck (60)

Sideboard (15)

Reading the List

The mana base is built so that every fetch can find a dual. Sacred Foundry and Elegant Parlor both carry the Mountain and Plains types, so all eleven fetches find either one. Only Arid Mesa can find the basic Mountain, so crack it for that land when you need Arena of Glory or Dalkovan Encampment to enter untapped.

The main-deck Blood Moon is a single copy for a reason. Under it, your own duals and utility lands become Mountains, and your two Plains are your only white sources. Before you cast it, make sure your board or your basics can still cast your white spells.

The softest slots are the singleton Haliya, Guided by Light, Static Prison and Blood Moon, plus the 2/2 split of Lightning Bolt and Thraben Charm. Those five spells, together with the third Goblin Bombardment, are where you tune for your local field.

The sideboard is aimed at the current field. Broodscale Bloodchief held 82 of 460 Top 8 slots, and all 82 of those lists ran four Eldrazi Temple (source: MTGTop8, 2026-10-01 to 2026-10-18). That makes the discount on Obsidian Charmaw and the sweep from Wrath of the Skies practical choices against the top deck, not speculative ones.

Mulligan Guide

What a Keep Needs

Your curve tops out at three mana, so you only need two lands. The hard part is the right two lands and the right spells. A keepable seven has:

• Two or more lands that produce both colors. Your fetches all find Sacred Foundry or Elegant Parlor, so one fetch fixes almost any hand. Two basics of the same type do not.
• A play on turn one or two. Ragavan, Nimble Pilferer, Guide of Souls, Ocelot Pride, Ajani, Nacatl Pariah, or Voice of Victory. This deck wins by deploying early, not by reacting.
• At least two creatures or tokens. Goblin Bombardment and Thraben Charm do nothing without bodies. A hand of burn and enchantments is not a game plan.

Bonus value comes from the Guide of Souls and Ocelot Pride pairing. Every creature that enters gains you life through Guide, which turns on Pride's end-step Cat.

Example Hands

Hand 1: Arid Mesa, Sacred Foundry, Guide of Souls, Ocelot Pride, Ajani, Nacatl Pariah, Galvanic Discharge, Voice of Victory. Verdict: snap keep. You get two one-drops on turn one, then Ajani on turn two triggers Guide and feeds Pride. Discharge clears a blocker, and the energy from Guide makes it bigger.

Hand 2: Windswept Heath, Ragavan, Nimble Pilferer, Ocelot Pride, Guide of Souls, Lightning Bolt, Galvanic Discharge, Ajani, Nacatl Pariah. Verdict: ship. It looks explosive, but every card after your first one-drop needs a second land, and a single fetch only casts one spell per turn. If you miss on the next draw, you're casting one-drops into blockers while Ajani sits in hand. One-landers are mulligans on the play and the draw.

Hand 3: Flooded Strand, Mountain, Elegant Parlor, Dalkovan Encampment, Plains, Seasoned Pyromancer, Guide of Souls. Verdict: keep. Five lands is normally too many. Seasoned Pyromancer fixes it: on turn three you discard two excess lands and draw two fresh cards. Dalkovan Encampment adds two attacking Warriors on later turns, which also triggers Guide. The Mountain lets Encampment enter untapped. This is a slow keep, and better on the draw.

Hand 4: Arid Mesa, Sacred Foundry, Galvanic Discharge, Lightning Bolt, Thraben Charm, Goblin Bombardment, Static Prison. Verdict: ship. The mana is perfect, but you have no creatures. Charm deals no damage with an empty board, Bombardment has nothing to sacrifice, and you're relying on the top of your deck to give you a clock. The only exception is a known creature-heavy aggro opponent where pure removal buys time, and even then, ship in game one when you don't know what you're facing.

Hand 5: Plains, Plains, Dalkovan Encampment, Ragavan, Nimble Pilferer, Seasoned Pyromancer, Lightning Bolt, Galvanic Discharge. Verdict: ship. Three lands, zero red sources, and every spell is red. Encampment only taps for white. This is the trap hand to watch for: count your colors, not just your lands.

Hand 6: Arid Mesa, Plains, Blood Moon, Ocelot Pride, Ragavan, Nimble Pilferer, Galvanic Discharge, Thraben Charm. Verdict: keep, and a great keep against nonbasic-heavy decks. Use Mesa to fetch a basic Mountain or Sacred Foundry for turn-one Ragavan. Pride comes down next to Plains, and a turn-three Moon follows. Lead with a basic, because Blood Moon turns your nonbasics into Mountains too.

Six-Card Hands

On six, keep any hand with two lands covering both colors and one early threat. A six with Voice of Victory or Seasoned Pyromancer is worth more than it looks: Voice protects your turns, and Pyromancer refills your hand. Ship a six only for the same flaws as a seven: one land, no threats, or a missing color.

On the Play vs. On the Draw

On the play, value speed. Turn-one Ragavan, Nimble Pilferer connects most often before blockers arrive, and two-landers stacked with one-drops are clean keeps. On the draw, your opponent's interaction comes down first and their early creatures blank Ragavan. Value hands with Galvanic Discharge or Lightning Bolt to clear the way. Keep top-heavy hands like Hand 3 more readily, because the extra card makes hitting land drops easier.

Matchup Adjustments

• Broodscale Bloodchief had the most Top 8 slots in the brief window (source: MTGTop8, 2026-10-01 to 2026-10-18). Every listed build runs Eldrazi Temple and Urza's Saga, and most run Ugin's Labyrinth, Gemstone Caverns, and Shifting Woodland (source: MTGTop8 deck exports, 2026-10-01 to 2026-10-18). That makes Blood Moon a reason to keep. Pressure plus removal for their creatures is the target. Discharge-light hands with slow starts are mulligans.
• UR Cutter Prowess lists all run Lightning Bolt (source: MTGTop8 deck exports, 2026-10-01 to 2026-10-18). Prioritize interaction and sturdy early bodies. Voice of Victory is a 1/3 that stops them from casting spells during your turn. A hand full of fragile one-drops with no removal is weaker here, especially on the draw.
• Control and interactive decks (UW Control, Dimir Control): keep threat density over removal. Voice of Victory and Seasoned Pyromancer are premium, and Hand 4 is an even clearer ship.
• Graveyard decks (Living End, Instant Reanimator): in game one, a hand with Thraben Charm gains value because it exiles graveyards. After boarding, keep hands with Rest in Peace aggressively, provided they also have a clock.

Sequencing & Key Lines

Turn 1: What to Lead With

Your default opener is Guide of Souls. It only counts other creatures entering, so every creature and token you make afterward banks energy and life. On the play into an empty board, Ragavan, Nimble Pilferer is the exception: a connected hit on turn two pulls ahead on mana and cards faster than anything else in the deck. On the draw, or against a deck that leads with cheap blockers, play Guide first and cast Ragavan later with dash.

The best turn-two follow-up to a turn-one Guide is Ocelot Pride plus a one-drop. Here is how that turn plays out:

• Each creature entering gives you 1 energy and 1 life.
• The life gain turns on Ocelot's end-step trigger, which makes a Cat.
• That Cat entering triggers Guide again.
• You start turn three holding the three energy that Guide's attack trigger needs.

Ajani, Nacatl Pariah on two is the other strong line. Ajani and his token each trigger Guide, so you bank 2 energy and 2 life in one cast.

Turns 2–3: Building the Engine

When you have more than one Cat on the battlefield, land Ajani before you start trading. Any other Cat dying flips him. That includes his own token, Ocelot Pride, and Ocelot's tokens.

The cleanest flip happens in combat. Attack with the Cat token. If it dies to a block, Ajani returns transformed, and you use the 0 ability in your second main phase. That ability deals damage equal to your creature count, and it only works if you control another red permanent. Your red permanents are:

• Ragavan, Nimble Pilferer
• Seasoned Pyromancer and its Elemental tokens
• Goblin Bombardment
• Blood Moon

Plan a red permanent before the flip, not after it.

Arena of Glory is your tempo land. Exert it on a Voice of Victory or a Seasoned Pyromancer for haste. A hasty Voice attacks right away and creates its two Warriors. A hasty Pyromancer swings the turn it refills your hand. Arena enters tapped without a Mountain, so get a Mountain-typed land down first. Sacred Foundry, Elegant Parlor, and basic Mountain all count.

Before you cast Seasoned Pyromancer, decide what you are discarding. Discarding nonland cards makes Elementals. Discarding excess lands just filters. With an empty hand late in the game, Pyromancer simply draws two.

Managing Energy

Energy is one shared pool fed by Guide of Souls, Galvanic Discharge, and Static Prison. It has three main uses:

• Guide's attack trigger costs three.
• Prison costs one at each of your first main phases.
• Any extra energy becomes Discharge damage.

Pay only as much as the kill requires. A Discharge that kills a 1-toughness creature while paying one leaves two energy banked. That bank often turns your next attack into a flying 3-power Angel.

When you attack with Voice of Victory, all your attack triggers go on the stack together, and you choose their order. Stack them like this:

1. Put the mobilize trigger on top so it resolves first.
2. The Warriors enter, and their Guide triggers resolve, giving you 2 energy.
3. Guide's attack trigger resolves last, and you can pay for it with that fresh energy.

Put the counters on a permanent attacker, not on a Warrior that will be sacrificed at end step.

Playing Around the Format's Interaction

Broodscale Bloodchief took the most Top 8 slots in this window, 82 of 460 (source: MTGTop8, 2026-10-01 to 2026-10-18). Dismember appeared in 79 of those 82 lists, and Kozilek's Command in all 82 (source: MTGTop8 deck exports, 2026-10-01 to 2026-10-18). UR Cutter Prowess ran four Lightning Bolt in all 30 of its Top 8 lists (source: MTGTop8 deck exports, 2026-10-01 to 2026-10-18). Every creature you play at two mana or less dies to Lightning Bolt, so expect your early threats to be answered.

Voice of Victory is your answer to that interaction. Once it resolves, your opponent cannot cast spells for the rest of your turn. They can still respond to Voice itself while it is on the stack. Use it like this:

• Cast Voice first in your main phase, then commit the rest of your turn behind it.
• With Voice down, nothing can be cast in response to Guide's reflexive trigger, during combat, or around an Ajani flip.
• Without Voice, assume your Guide target can be killed in response. Point the counters at the creature whose death costs you least.

Ragavan, Nimble Pilferer on dash returns to your hand each end step, so it never sits on the battlefield during your opponent's turn. Use dash when your opponent is holding up instant-speed interaction and you need the hit more than the permanent body.

Goblin Bombardment Lines

Don't spend Bombardment early on one damage at a time. It works best in these spots:

• Sacrifice mobilize Warriors and Dalkovan Encampment tokens after combat damage. They were going to be sacrificed anyway.
• Sacrifice a Cat to force an Ajani flip on your own schedule.
• Sacrifice a creature in response to removal so its damage isn't wasted.
• Count it as reach. Your total damage is your board size plus Lightning Bolt plus Ajani's 0.

Blood Moon and Land Order

Under your own Blood Moon, every nonbasic land becomes a Mountain and taps only for red. That includes Sacred Foundry, Elegant Parlor, and Dalkovan Encampment. Before you cast Moon, crack fetches for basic Plains so you keep white mana. Crack them for basic Mountain only when you already have enough white.

End-Step Edges

• Haliya, Guided by Light. Cast it with warp for one mana on a turn when you will gain 3 or more life. Haliya gains life when Ragavan's Treasure, Ajani's token, or mobilize Warriors enter. That turns on its end-step draw and also Ocelot's token. Then you can recast Haliya from exile on a later turn.
• Ocelot Pride with the city's blessing. Ocelot's trigger and the mobilize sacrifice both happen at the beginning of the end step, and you choose their order. Resolve Ocelot's trigger first and the Warriors get copied. The copies are not the tokens mobilize told you to sacrifice, so they stay. This only works if you have not already sacrificed those Warriors to Goblin Bombardment.
• Dalkovan Encampment. Once you run out of spells, spend spare mana on its ability before attacking every turn. The two Warriors trigger Guide of Souls for energy and life, and that life feeds Ocelot.

Matchup Matrix

Broodscale Bloodchief

This is the deck you will face most. It took 82 of 460 Top 8 slots (source: MTGTop8, 2026-10-01 to 2026-10-18). Every list runs Urza's Saga and Eldrazi Temple, and nearly all run Ugin's Labyrinth, Gemstone Caverns and Shifting Woodland. All of those are nonbasic, so Blood Moon turns every one of them into a Mountain.

They also play Vexing Bauble in 78 of 82 lists (source: MTGTop8, 2026-10-01 to 2026-10-18). Its counter does nothing against you, because every spell in your deck costs mana.

Your plan:

• Use Galvanic Discharge on their early creatures.
• Attack behind Voice of Victory so nothing they hold can be cast on your turn.
• Close fast before their top end arrives.

After boarding, add Molten Rain and Obsidian Charmaw. Check their lands first: each one that can produce {C} makes Charmaw cost one less. For that side of the matchup, see our Broodscale Bloodchief Modern guide.

UR Cutter Prowess

All 30 lists run four Lightning Bolt and four Lava Dart (source: MTGTop8, 2026-10-01 to 2026-10-18). Your X/1s and X/2s will die, so lean on life gain to make their burn plan fall short. Ocelot Pride's lifelink and first strike, Guide of Souls triggers and Haliya, Guided by Light all push your total out of reach.

Trade early and save Galvanic Discharge for their best threat. Voice of Victory stops them from casting anything during your combat. After boarding, High Noon limits them to one spell per turn, which breaks their multi-spell turns. See our UR Cutter Prowess Modern guide.

Rakdos Delirium

This is a grind. Spread your threats across creatures, tokens and Ajani, Nacatl Pariah so one removal spell never resets you. Seasoned Pyromancer refuels your hand, and its graveyard ability gives you two late-game bodies. Ragavan, Nimble Pilferer steals cards when it connects.

Sanctifier en-Vec is your best sideboard card here. It has protection from black and from red, and it exiles black and red cards from all graveyards. See our Rakdos Delirium Modern guide.

Boros Aggro

Board stalls decide this matchup, and Goblin Bombardment breaks them. Sacrificing a Cat token both pings and flips Ajani, Nacatl Pariah. Once flipped, the 0 ability adds a body and deals damage equal to your creature count.

Ocelot Pride's first strike blanks X/1 attackers. A Guide of Souls trigger turns a ground creature into a flier that goes over their stall. See our Boros Aggro Modern guide.

Scepter Chant

Your key card is Voice of Victory: anything they want to cast on your turn simply can't be cast. Protect it, attack every turn, and use Static Prison to exile their key nonland permanent. Don't durdle. Ragavan, Nimble Pilferer on turn one is ideal here.

After boarding, High Noon limits them to one spell per turn. It binds you too, but your plan needs fewer spells per turn than theirs does.

Pinnacle Affinity

Kill their early creatures with Galvanic Discharge and Lightning Bolt before their board snowballs. After boarding, Wrath of the Skies is your trump. You can pay energy you have already banked from Guide of Souls and Galvanic Discharge, so it destroys more for less mana.

Wrath also hits your own permanents. Fire it when the trade favors you, then rebuild. See our Pinnacle Affinity Modern guide.

Rest of the field

Graveyard combo: Thraben Charm exiles graveyards straight from the main deck. After boarding, add Rest in Peace and Sanctifier en-Vec. Hold Charm for the turn they commit to the graveyard.

Big mana / ramp: Pair a clock with Blood Moon, Molten Rain and Obsidian Charmaw. One timely land hit plus your early pressure is usually enough.

Control: Commit enough threats to beat their removal, but not so many that a single answer wrecks you. Voice of Victory stops their instant-speed interaction on your turn. Seasoned Pyromancer turns dead cards into fresh ones.

Spell-based combo: High Noon and Voice of Victory cap what they can cast and when. Keep your fastest hands.

Sideboard / Tech Guide

The 15 cards fall into three packages. Mana denial is the second Blood Moon, Molten Rain and Obsidian Charmaw. Graveyard and free-spell hate is Rest in Peace, Vexing Bauble and Sanctifier en-Vec. Board and spell control is Wrath of the Skies, High Noon and Wear/Tear. Most matchups use one package and leave the others in the box. Broodscale Bloodchief was the most common Top 8 archetype in the brief's window, with 82 of 460 slots (source: MTGTop8, 2026-10-01 to 2026-10-18). Build your plan around beating it first.

Broodscale Bloodchief

Their mana base leans on nonbasics such as Eldrazi Temple and Urza's Saga. That makes land destruction a real plan.

• Molten Rain: it takes a land and deals 2 to them if that land was nonbasic, which adds to your clock.
• Blood Moon: two copies is enough to find one in a normal game.
• Wear/Tear: this is the sideboard's dedicated slot for permanent-based artifact and enchantment threats.
• What comes out: keep Galvanic Discharge for creatures and cut Lightning Bolt instead. Thraben Charm's modes are its weakest here.
• Obsidian Charmaw: it costs {1} less for each of their lands that can produce {C}. Count their colorless sources in game one. If the discount is large, bring it in over a Wear/Tear.

UR Cutter Prowess and spell-chaining combo

Both decks want to cast several cheap spells in one turn. High Noon caps every player at one spell per turn.

• High Noon on your side: it limits you too. Your hands are mostly one- and two-drop creatures, so you lose less than they do.
• High Noon late: {4}{R} and sacrificing it deals 5 to any target, which often ends the game.
• Voice of Victory: it already stops their spells during your turn. With High Noon out, they get one spell on their own turn and none on yours.
• Sanctifier en-Vec: protection from red blanks their red removal and blocks their red creatures all day.

Rakdos Delirium

Sanctifier en-Vec is the whole plan here.

• Protection: protection from black and red means their removal can't target it.
• Graveyard: its enter trigger exiles every black and red card from all graveyards. After that, their black and red cards get exiled instead of reaching the graveyard, so a delirium deck can't refill it.
• Rest in Peace: only add it if their graveyard plan keeps beating you, and read the Ajani note below first.

Boros mirror and creature aggro

• Wrath of the Skies energy: the energy you bank from Guide of Souls, Galvanic Discharge and Static Prison counts toward the Wrath payment. You can cast it for small X and still pay enough energy to sweep.
• Wrath and your own board: tokens have mana value 0, so they always die. Every creature in your list costs 3 or less. Wrath is a reset button for when you're behind on board, not a one-sided sweeper.
• Sanctifier en-Vec: it walls their red creatures and can't be hit by Lightning Bolt, Galvanic Discharge or Goblin Bombardment.
• Ragavan: it comes out because a 2/1 rarely connects through a cluttered mirror board.

Pinnacle Affinity

• Wrath of the Skies: it destroys artifacts as well as creatures. Pay exactly what clears their cheap permanents.
• Wear/Tear: it handles whatever survives the sweep.
• What comes out: Seasoned Pyromancer is too slow to race here.

Graveyard decks

• Rest in Peace: it exiles all graveyards when it enters and stops anything from reaching them afterward.
• Vexing Bauble: it counters any spell cast without spending mana. It does double duty against decks that put their payoff on the stack for free.
• Thraben Charm: it stays in, because exiling graveyards at instant speed is still live.

Big mana and control

• Win plan: deny lands early and keep attacking.
• Removal: cut Thraben Charm and Lightning Bolt against big mana. Against control, cut Galvanic Discharge instead, since it can only hit creatures or planeswalkers. Lightning Bolt can still go face.
• Voice of Victory: it is your best card against control because their instant-speed answers can't be cast on your turn.

Interactions to know before you board

• Blood Moon and your own mana: it turns your Sacred Foundry, Elegant Parlor, Dalkovan Encampment and Arena of Glory into Mountains, which cuts off your white. Fetch your two Plains early in any game where you might cast it, and sequence so a Plains is already on the battlefield.
• Rest in Peace and your creatures: under it, your creatures are exiled instead of dying. That shuts off Ajani, Nacatl Pariah's transform and Seasoned Pyromancer's graveyard ability. Goblin Bombardment still works, because sacrificing is the cost.
• Sanctifier en-Vec and your red cards: it also exiles your own red cards and red permanents that would hit the graveyard, including Elemental tokens and a dying Ragavan, Nimble Pilferer. Your white Cat tokens still die normally, so Ajani still flips.
• Static Prison energy: it costs {E} every turn. After Wrath of the Skies spends your energy, check that you can still pay or the Prison leaves.

Tech Choices & Variations

The Main-Deck Flex Slots

The core is fixed: four each of Ajani, Nacatl Pariah, Guide of Souls, Ocelot Pride, Ragavan, Nimble Pilferer, Seasoned Pyromancer, Voice of Victory and Galvanic Discharge. The real decisions sit in about eight slots: the two Lightning Bolt, two Thraben Charm, third Goblin Bombardment, lone Blood Moon, Static Prison and Haliya, Guided by Light.

• Lightning Bolt vs. more answers. Bolt is the only main-deck burn that can hit a player. Galvanic Discharge only targets creatures and planeswalkers. Two Bolts give you reach without diluting removal. Against creature-light combo, you can trim one for a second Static Prison-style answer from the board. The cost is that you lose closing speed.
• Thraben Charm count. Two copies cover three jobs: creature removal that scales with your board, enchantment removal and graveyard exile. If your room is full of graveyard decks, a third copy is reasonable. Take it from a Bolt, not a creature, because the damage mode needs a board to be good.
• Static Prison. This is the catch-all one-mana answer to any nonland permanent. It pays for itself with two energy and then taxes one energy every turn. With Guide of Souls and Galvanic Discharge feeding energy, upkeep is usually free. If you expect a field heavy on permanent-based threats, it can become two copies. That pulls energy away from Angel attacks and Discharge damage, so don't go past two.
• Haliya, Guided by Light. Warp for {W} lets you cast her for one mana and recast her later. Because she gains life on every creature or artifact entering, she pushes you toward drawing at end step. One copy is a value top-end. Going to two makes your curve clunkier against fast decks.
• The third Goblin Bombardment. Bombardment turns your tokens into reach and lets you sacrifice Cats on purpose to flip Ajani. A fourth copy makes the deck more all-in. Three keeps you from drawing a dead pair against sweepers.

The Blood Moon Question

The list runs one Blood Moon main and one in the sideboard. Moving the second copy main is the biggest swing available, and the cost is your own mana. Under Blood Moon, your Sacred Foundry, Elegant Parlor, Dalkovan Encampment and Arena of Glory are Mountains, and any fetchland you haven't cracked loses its ability. Your only basic white sources are two Plains. Before you cast Moon, crack your fetches for basics, and fetch Plains early whenever you hold Moon. Running two Moons main is only right if you expect to face greedy nonbasic mana bases much more often than fair decks.

Mana Base Levers

Elegant Parlor enters tapped, so two copies are already the ceiling. Dalkovan Encampment gives white mana plus a late-game mana sink that makes extra attackers. Arena of Glory gives haste and a burst of red mana. Both enter untapped only if you control a Mountain, which Sacred Foundry and Elegant Parlor count as. Trading one utility land for a third Plains makes Blood Moon much safer. The price is a weaker late game when you flood.

Sideboard Configuration

• Wrath of the Skies scales with energy, so banked energy from Guide of Souls and Galvanic Discharge makes it bigger. It also destroys your own cheap creatures and Goblin Bombardment. Plan your X carefully.
• High Noon limits every player to one spell per turn. It shuts down multi-spell turns, and it can be sacrificed later as a five-damage finisher.
• Rest in Peace and Sanctifier en-Vec are graveyard hate with different targets. Rest in Peace hits everything. Sanctifier hits only black and red cards but brings a body with protection from both colors. Rest in Peace also stops your own Seasoned Pyromancer graveyard ability and your Cats from "dying" for Ajani, so prefer Sanctifier when it covers the opponent's key cards.
• Molten Rain, Obsidian Charmaw and the second Blood Moon are three ways to punish land-based strategies. Charmaw costs less for each opposing land that can produce colorless mana, which makes it the cheapest of the three against those mana bases.
• Vexing Bauble counters spells cast without mana being spent. None of your own spells are cast that way, so it never hurts you.

Tuning for Your Field

Recent data favors the artifact-ramp adjustment. Broodscale Bloodchief took 82 of 460 Top 8 slots (source: MTGTop8, 2026-10-01 to 2026-10-18), far more than any other archetype. That makes Wrath of the Skies and Static Prison the slots to protect.

Graveyard strategies are a smaller but real group: Living End took 17 slots and Instant Reanimator 14 (source: MTGTop8, 2026-10-01 to 2026-10-18). Keep at least two graveyard answers across your 75.

UR Cutter Prowess took 30 slots (source: MTGTop8, 2026-10-01 to 2026-10-18). Its sideboard runs Obsidian Charmaw in 19 of 30 lists (source: MTGTop8 deck exports, 2026-10-01 to 2026-10-18). Expect your nonbasic lands to be targeted after game one, and fetch basics when the trade is close.

Budget Options

The deck runs about $805 at TCGplayer market prices (approximate). That cost is concentrated in two places: the playset of Ragavan, Nimble Pilferer and the mana base, meaning the eleven fetchlands (Arid Mesa, Flooded Strand, Windswept Heath, Marsh Flats) plus three Sacred Foundry. The cheap creatures, burn, and enchantments make up a much smaller share. Check current prices before you buy, because singles move. Plan around this rule: you can compromise on lands and Ragavan, but you can't compromise on the engine.

Non-negotiable: buy these first

• The creature core: Ajani, Nacatl Pariah, Guide of Souls, Ocelot Pride, Voice of Victory, Seasoned Pyromancer. These are the deck. Guide of Souls needs creatures entering to make energy and life. Ocelot Pride needs life gain to make Cats. Ajani, Nacatl Pariah needs Cats dying to flip. Cut any of them and the other pieces stop working together.
• Interaction: four Galvanic Discharge, three Goblin Bombardment, Lightning Bolt, Thraben Charm. Without Bombardment you lose your sac outlet, your reach, and your on-demand way to flip Ajani.

Budget swap 1: the mana base

Replace all eleven fetches with basics and the extra copies of Elegant Parlor. Here is a workable 22-land starting point:

This gives you sixteen white sources and thirteen red sources. You need more Mountains here than the full list runs because Dalkovan Encampment and Arena of Glory both enter tapped unless you control a Mountain. Basic Mountain, Sacred Foundry, and Elegant Parlor all count for that.

What you give up:

• Flexibility. A fetch is whichever land your hand needs. A basic is locked to one color, so you'll see more hands with the wrong color for your one-drops.
• Tempo. Four Elegant Parlor means more turns where a land enters tapped. That hurts most when you need to curve a one-drop into Ajani, Nacatl Pariah.

What you gain:

• You stop paying 1 life per fetch.
• Your own Blood Moon costs you almost nothing. Under Moon your basic Plains still tap for white, while every nonbasic, including Dalkovan Encampment, becomes a Mountain.

The basic-heavy build is a real, playable configuration. It is not a crippled one.

Budget swap 2: Ragavan, Nimble Pilferer

Four Ragavan is the single biggest saving. The cleanest in-list replacement is:

• +2 Lightning Bolt (to four)
• +1 Thraben Charm
• +1 Haliya, Guided by Light

Haliya, Guided by Light is legendary, so a second copy can be awkward. Warp softens that, because you can cast the extra copy for {W} and let it return to exile.

The cost is larger than it looks:

• Turn-one pressure and resources. You lose a one-drop that makes Treasure, steals cards, and threatens a hasty dash hit later in the game.
• Creature count. You drop four creatures, which means fewer Guide of Souls triggers and smaller Thraben Charm damage.
• Ajani's damage. You lose a red permanent. Ajani, Nacatl Pariah's flipped side only deals damage with its 0 ability if you control a red permanent other than Ajani. With Ragavan gone, that job falls to Seasoned Pyromancer, its tokens, Goblin Bombardment, and Blood Moon.

Expect fewer free wins on the play and more grindy games.

Budget swap 3: the sideboard

Don't buy all fifteen at once. Buy for the field you expect.

• Broodscale Bloodchief was the most-played archetype in Modern Top 8s (82 of 460 slots; source: MTGTop8, 2026-10-01 to 2026-10-18). Every one of those 82 lists ran four Urza's Saga and four Eldrazi Temple (source: MTGTop8 deck exports, 2026-10-01 to 2026-10-18). Both are nonbasic lands, so Molten Rain, Obsidian Charmaw, and your second Blood Moon are high-priority pickups.
• Graveyard decks: if your room is heavy on them, Rest in Peace comes next.
• Wide boards and hard counts: buy Wrath of the Skies and High Noon when you know you need them.

Upgrade path

1. Engine plus budget mana plus the Ragavan replacement. This is fully functional.
2. Sideboard for your local field. Sideboard games make up most of a match, so this ranks above maindeck upgrades.
3. Ragavan, Nimble Pilferer. This is the biggest single power gain. It restores your creature density and turn-one pressure.
4. Arid Mesa. It is the only fetch in the list that finds a basic Mountain as well as every Plains-typed land. That makes it the most flexible fetch, so buy those four before the others. Cut Elegant Parlor back to two as you add them.
5. The remaining fetches. Flooded Strand, Windswept Heath, and Marsh Flats all do the same job here: they find Plains, Sacred Foundry, or Elegant Parlor. Buy them in whatever order is cheapest, trading basic Plains out as they arrive.

At every stage, keep the white and red source counts roughly where the table puts them. A list that is cheaper but color-screwed is worse than one that is cheaper and consistent.

Common Mistakes

1. Treating Galvanic Discharge as a 3-damage spell

Galvanic Discharge gives you three energy, then lets you pay any amount. The mistake is dumping all three into a 2-toughness creature. That leftover energy is the same pool that pays for the Guide of Souls attack trigger and keeps Static Prison on the table. The reverse is true too: energy banked from earlier Guide triggers lets a single Discharge kill something bigger than 3 toughness.

The fix: Pay exactly lethal, and count your energy before you commit it. Before every attack, decide whether this turn's energy goes to Guide's counters, Prison upkeep, or a future Discharge. Spending it on whatever comes up first is how you lose a Prison you needed.

2. Casting your other spells before Voice of Victory

Voice of Victory stops your opponents from casting spells during your turn, but only once it has resolved. If you cast Seasoned Pyromancer or Ajani, Nacatl Pariah first, the opponent can still answer those spells with instant-speed interaction.

The fix: When Voice is in hand alongside other threats, it goes first in your main phase. The spells you cast after it resolve without a response. Remember that Voice only protects your turn. Expect it to be removed on theirs, and don't build a turn that only works if Voice survives the next untap.

3. Letting temporary tokens die for nothing

Mobilize Warriors from Voice of Victory and the Warriors from Dalkovan Encampment are sacrificed at the beginning of the next end step. Each one that goes to the graveyard without passing through Goblin Bombardment first is a point of damage you gave away. Players also aim the Guide of Souls counters at a token, which puts two +1/+1 counters and flying on a creature that disappears in a few minutes.

The fix: With Bombardment out, sacrifice the doomed tokens to it. Do it in response to the end-step sacrifice trigger if you don't need them earlier. Put Guide's counters on a creature you keep, such as Voice itself, Ragavan, Nimble Pilferer, or Ocelot Pride.

4. Ordering end-step triggers wrong once you have the city's blessing

With ten or more permanents, Ocelot Pride creates a copy of each token that entered this turn. That includes Mobilize Warriors, Encampment Warriors, Ragavan, Nimble Pilferer Treasures, and the Cat Pride just made. The Mobilize sacrifice and the Ocelot trigger both happen at the beginning of your end step, and you choose their order. If the sacrifice resolves first, there are no Warriors left to copy.

The fix: Put the sacrifice trigger on the stack first and Ocelot's trigger on top, so Ocelot resolves first. The copies aren't subject to the sacrifice and stay permanently. Each copy also triggers Guide of Souls for life and energy. Then, with the sacrifice trigger still waiting, throw the original Warriors into Goblin Bombardment. This also means you shouldn't sacrifice Warriors during combat when you have the blessing. Keep them alive until the end step.

Also, Ocelot does nothing without life gain that turn. If Pride can't connect safely, make sure a creature enters alongside Guide of Souls or Haliya, Guided by Light before you pass the turn.

5. Casting Thraben Charm too early

The damage mode of Thraben Charm counts your creatures as it resolves. If you cast it in your precombat main phase, you miss the Mobilize tokens, which only appear when you attack.

The fix: When the target can wait, cast the Charm after attackers are declared, once the Warriors are on the battlefield. With Voice of Victory out, the opponent can't respond to it with a spell. Don't forget the enchantment and graveyard modes either. Holding Charm for removal when it should be exiling a graveyard is its own mistake.

6. Fetching the wrong lands before Blood Moon

Blood Moon turns your own nonbasics into Mountains, and they lose their abilities. Uncracked fetchlands become Mountains and can no longer fetch. Sacred Foundry and Elegant Parlor stop producing white. Dalkovan Encampment stops making Warriors. Under the Moon, your only white mana comes from your two basic Plains.

The fix: If Blood Moon is part of your plan, crack your fetches for a basic Plains before you cast it. Don't fetch Sacred Foundry by default. Make sure your remaining hand can be cast off one white source and a pile of Mountains, or you lock yourself out as well as your opponent.

7. Flipping Ajani on autopilot

Ajani, Nacatl Pariah transforms when another Cat you control dies. You can force that yourself by sacrificing his Cat Warrior or an Ocelot Pride Cat to Goblin Bombardment. Players often miss that line. They also flip him and then fire the 0 ability expecting damage, when it needs a red permanent other than Ajani.

The fix: Before you flip Ajani, check for a red permanent. Goblin Bombardment, Ragavan, Nimble Pilferer, Seasoned Pyromancer, and its Elemental tokens all qualify. The 0 ability counts all creatures you control, including the new Cat. Use it after Mobilize Warriors or Pyromancer tokens have hit the board and it becomes real removal or reach.

Tournament Prep & Final Notes

The deck rewards precision more than creativity. Most of its losses come from mis-tracked resources and misordered triggers. Your prep should go into making the engine automatic, so your attention stays on the opponent.

What to Practice

• Energy budgeting. Guide of Souls, Galvanic Discharge and Static Prison all feed the same pool, and Guide's attack trigger and Prison's upkeep both drain it. At the start of each turn, decide what the pool is for this turn: an Angel, a bigger Discharge, or keeping Prison alive. Don't let it drift.
• Ajani flip lines. Run the sequence of Goblin Bombardment sacrificing a Cat until it is reflexive, including doing it in response to removal on the Cat.
• Blood Moon turns. Practice fetching basics before Blood Moon lands. The list has only two Plains and one Mountain. Under Moon, Sacred Foundry, Elegant Parlor and Arena of Glory tap only for red, and Dalkovan Encampment loses its abilities. Uncracked fetches also become Mountains, so crack them first.
• The two most-represented decks. Broodscale Bloodchief took 82 of 460 Top 8 slots, and UR Cutter Prowess took 30 (source: MTGTop8, 2026-10-01 to 2026-10-18). Get sideboarded reps against both. Every Broodscale Top 8 list in that window ran four Eldrazi Temple and four Urza's Saga (source: MTGTop8, 2026-10-01 to 2026-10-18), so Blood Moon has real targets there.

Rules Interactions to Know Cold

• Voice of Victory stops spells, not abilities. Opponents can't cast spells during your turn, end step included, so their instants have to come on their own turn. Activated abilities still work, so don't assume full immunity.
• Know which creatures are Cats. Only Ajani, Nacatl Pariah, his Cat Warrior token, Ocelot Pride and Ocelot's tokens are Cats. Mobilize Warriors, Dalkovan Encampment Warriors and Seasoned Pyromancer Elementals don't flip Ajani.
• Use temporary tokens before they go. Mobilize and Encampment tokens are sacrificed at the beginning of the next end step. Feed them to Goblin Bombardment first.
• Turn on Ajani's 0 ability. His 0 ability needs a red permanent other than Ajani. That can be Ragavan, Nimble Pilferer, Pyromancer, its Elementals, Goblin Bombardment or Blood Moon. The red Warriors from mobilize also count, and they are still around in your second main phase. Lands are not red. The ability creates its token before the damage is counted, so the new Cat adds a point.
• Order your end-step triggers. When Ocelot Pride and Haliya, Guided by Light both trigger, resolve Ocelot first. Haliya's draw checks your life gained only when it resolves. Ocelot's Cat entering triggers Haliya's lifegain and Guide of Souls's lifegain, and that life can get you to three before the draw resolves.
• Galvanic Discharge scales both ways. You can pay less than three and bank the rest. You can also dump stored energy into it for a bigger hit.
• Wrath of the Skies uses your banked energy. It lets you pay any amount, not just X, so a stocked pool makes a cheap Wrath huge. It also kills your own tokens and one-drops. Plan which threats you keep before you sideboard it in.
• Your graveyard hate hits you too. Under Rest in Peace, your Cats are exiled instead of dying, so Ajani never flips. Sanctifier en-Vec exiles red cards from your graveyard, which turns off Pyromancer's graveyard ability. Weigh both before you board them in.
• High Noon limits you as well. It applies to you, and this deck likes to deploy two cheap threats in one turn. Under it, play one high-impact spell per turn.
• Vexing Bauble doesn't hurt you. Everything you cast costs mana, including dash and warp, so it only counters the opponent's free spells.

Clock and Time Management

The deck isn't slow, and games usually end well before time is a concern. When you do lose minutes, it is to trigger handling. Turns with Guide, Ocelot and Haliya can produce many small triggers. Keep these habits:

• Track energy with a dedicated die that never doubles as anything else.
• Announce triggers in batches: "two tokens, two life, two energy."
• Say your end-step trigger order out loud.
• Write your life total after every gain.

Clean communication saves time. It also prevents disputes in exactly the turns where your opponent is most motivated to call a judge.

Make your sideboard decisions before the event, not between games. Write a short swap card for your expected opposing decks. Decide in advance which of Rest in Peace, Sanctifier en-Vec or Wrath of the Skies each matchup actually wants, given how they interact with your own deck.

Final Assessment

This list wins a Regional Championship the way strong aggro decks should. It has a dense curve of one- and two-mana threats that each demand an answer. Its cheap removal clears blockers and answers opposing engines. Voice of Victory denies opponents interaction on your turn. Goblin Bombardment converts any board into reach.

The single Blood Moon, Static Prison and Haliya, Guided by Light are what lift the main deck above a pure creature pile. They answer nonbasic mana, problem permanents and the grind game without diluting the curve.

The 2026-10-12 Banned and Restricted announcement made no changes to Modern, and the next announcement is 2026-11-30 (source: Wizards of the Coast, 2026-10-12). You can register these 75 as they are without worrying about the card pool shifting before your event.

Pick it up if you're willing to track resources carefully every turn. The power is all in the card choices. Whether it converts into wins depends on your energy math and trigger order.

Frequently Asked Questions

How does Boros Energy win games in Modern?

It puts more bodies on the battlefield than the opponent can answer one at a time. It then turns them into damage from three directions: combat, Goblin Bombardment activations, and Ajani, Nacatl Pariah's planeswalker side. The goal is a board where removing any single piece barely slows you down.

What are the key engine cards in Boros Energy?

Guide of Souls is the hub, giving 1 life and 1 energy whenever another creature enters. Ocelot Pride turns that life gain into Cat tokens, and Ajani, Nacatl Pariah flips when another Cat dies. Voice of Victory adds attackers and stops opponents from casting spells during your turn.

What kinds of decks and cards give Boros Energy the most trouble?

Because the deck goes wide with small bodies, its main threats are sweepers, large blockers that outclass your tokens, and strategies that ignore combat entirely. Its main-deck answers are cheap and flexible but few, so you have to plan which threats to answer and which to race.

What makes a keepable opening hand for Boros Energy?

A keepable seven has two or more lands that produce both colors, a play on turn one or two, and at least two creatures or tokens. Ship one-landers on the play and the draw, hands with no creatures, and hands missing a color.

How can I build Boros Energy on a budget?

Replace the eleven fetchlands with basics and extra copies of Elegant Parlor, and replace Ragavan, Nimble Pilferer with two more Lightning Bolt, one Thraben Charm, and one Haliya, Guided by Light. Never compromise on the creature core and interaction, because those cards make up the engine.

Why should Voice of Victory be cast before my other spells?

Voice of Victory only stops opponents from casting spells during your turn once it has resolved. Cast it first in your main phase so the threats you cast after it can't be answered with instant-speed interaction.

How do I avoid locking myself out with my own Blood Moon?

Under Blood Moon, your nonbasics become Mountains and uncracked fetches can no longer fetch. Before you cast it, crack your fetches for a basic Plains so you keep white mana, and make sure your hand can be cast off one white source.

What should I practice before taking Boros Energy to a tournament?

Practice energy budgeting each turn, the line of sacrificing a Cat to Goblin Bombardment to flip Ajani, and fetching basics before Blood Moon. Also get sideboarded reps against Broodscale Bloodchief and UR Cutter Prowess, the two most-represented decks.
