Archetype Overview
UR Aggro is a tempo-prowess deck built around one idea: cast more spells per turn than your opponent can keep up with, and make every one of them hit. The 60 cards are 12 creatures, 18 lands, and 30 noncreature spells, and many of those spells cost zero or one mana. The list took Top 4 at the MTGO Showcase Challenge on 2026-10-17 (286 players, piloted by O_danielakos). That is a strong result for a deck that wins by stacking small, cheap threats until the opponent runs out of time.
What the Deck Is
Think of it as a spell-count engine dressed up as a red aggro deck. Your creatures, Monastery Swiftspear, Dragon's Rage Channeler, and Slickshot Show-Off, all cost one or two mana and all scale with noncreature spells. Cori-Steel Cutter turns the second spell you cast each turn into a hasty attacker. The blue half adds selection and card flow through Preordain and Expressive Iteration. The red half supplies reach with Lightning Bolt and Lava Dart.
The Plan
Land an early threat, then use cheap spells to pump it, clear blockers, or dig for the next threat. Each spell does double duty: it has its own effect, and it adds damage through prowess, Show-Off's +2/+0, or a Cori-Steel Cutter Monk. You are not trying to out-card the opponent in a long game. You are trying to force bad blocks and awkward removal while your life total is still an asset, then finish with burn.
Why the Plan Is Strong
- Free spells break the mana ceiling. Several cards trigger prowess and count toward Flurry without costing mana:
- Mishra's Bauble and Tormod's Crypt cost zero.
- Mutagenic Growth can be paid with 2 life.
- Lava Dart's flashback costs a Mountain, not mana.
- Cori-Steel Cutter keeps making threats. Flurry counts any second spell, creature spells included. Each Monk token has prowess, and you may attach the Cutter to it, giving it +1/+1, trample, and haste. The result is a fresh attacker every turn that hits immediately, so one-for-one removal falls behind.
- Plot turns tempo into a free turn. You can plot Slickshot Show-Off for {1}{R} on a turn when you have mana to spare. On a later turn, cast it for free alongside your other spells. That free creature spell also counts toward Flurry, so plotting a Show-Off early sets up an explosive turn later.
- Delirium is built in, not forced. The list fills four card types in your graveyard almost by accident:
- Artifacts: sacrificed Baubles and Crypts.
- Instants: Lightning Bolt, Unholy Heat, Mutagenic Growth, Violent Urge.
- Sorceries: Preordain, Expressive Iteration.
- Lands: cracked fetches, a sacrificed Fiery Islet, or the Mountain you give up for Lava Dart flashback.
- The mana base feeds the spells. Every fetchland can find a Mountain-typed land: Steam Vents, Stomping Ground, Thundering Falls, or a basic Mountain. That keeps Lava Dart flashback live and puts land cards in your graveyard for delirium. Stomping Ground also lets you pay green for Mutagenic Growth when life matters.
- You don't run out of gas easily. Several cards keep your hand stocked:
- Expressive Iteration digs three deep and lets you play the exiled card, land included.
- Mishra's Bauble replaces itself.
- Fiery Islet cashes in for a card late.
Where It Bends
Your life total is a resource you spend constantly: fetches, shocklands, Fiery Islet, and Phyrexian mana on Mutagenic Growth. Against other fast decks, that cost is real, and careless payments lose races. Delirium also relies on your graveyard, so opponents who exile graveyards can shrink Dragon's Rage Channeler and blunt Unholy Heat and Violent Urge.
With only 12 creatures plus Monk tokens, heavy, repeated creature removal can strand your pump spells. Your counter is to keep Cori-Steel Cutter generating bodies and to save burn for the opponent's face rather than their blockers.
Who Should Pick It Up
Pick this deck if you like dense, decision-heavy turns. Ordering free spells, choosing when to equip, and timing a plotted Show-Off is where you win. It rewards players who count damage across several triggers in one turn and who treat life as currency rather than a score.
Avoid it if you want to sit back and react. Your posture is proactive, and most of your interaction is burn that also points at the opponent.
At an estimated $381 (TCGplayer market prices, approximate), the deck gives you a high-skill-ceiling Modern deck whose results scale directly with how cleanly you sequence.
Core Strategy & Game Plan
UR Aggro wins by converting cheap noncreature spells into damage. Almost every card in the 60 either deals damage, pumps a creature, or exists to be cast cheaply so that something else on your board gets bigger. Your threats are small and fast; your spells make them lethal. You are the beatdown in nearly every game, and your job is to end it before the opponent's plan matters.
The Engine: Every Spell Is an Attack Step
Each noncreature spell triggers up to four payoffs at once:
- Monastery Swiftspear and every Monk token get +1/+1 from prowess.
- Slickshot Show-Off gets +2/+0, on a hasty flier.
- Dragon's Rage Channeler surveils 1, filtering your draws and filling the graveyard toward delirium.
- Cori-Steel Cutter makes a Monk if it's your second spell that turn.
A single Mishra's Bauble with Swiftspear, Show-Off and an equipped Monk in play is several points of damage for zero mana that also replaces itself. That is the math the deck runs on: spells are cheap, and the creatures multiply each one.
Cori-Steel Cutter and the Second Spell
Cutter is your strongest card when you deploy it early. Flurry checks for your second spell each turn, yours or the opponent's. It counts creature spells as well as noncreature spells. The list is built so you hit that count cheaply:
- Zero mana: Mishra's Bauble, Tormod's Crypt, Mutagenic Growth paid with 2 life, and a plotted Slickshot Show-Off cast without paying its mana cost.
- Two spells for one mana: Lava Dart followed by its flashback, which costs you a Mountain. Basic Mountain, Steam Vents, Stomping Ground and Thundering Falls all qualify. Fiery Islet and the fetchlands do not.
- Extra cards: Expressive Iteration lets you play the exiled card this turn, which often turns into the second spell.
When the Monk arrives, you may attach Cutter to it for free. The token then gets +1/+1, trample and haste and can attack immediately. Because Flurry also works on the opponent's turn, holding Lightning Bolt plus a free spell for their end step gives you a Monk without spending mana on your own turn. Two Cutters trigger separately, so a second copy is never dead.
Delirium
Delirium upgrades three cards. Dragon's Rage Channeler becomes a 3/3 flier, Unholy Heat deals 6 damage, and Violent Urge grants double strike. You need four card types in your graveyard, and the deck supplies them naturally:
- Land: cracked fetchlands.
- Artifact: Bauble, Crypt and Cutter.
- Instant: Bolt, Growth, Urge and Heat.
- Sorcery: Preordain and Expressive Iteration.
- Creature: whichever creatures die or get surveiled away.
Two cautions. A flashed-back Lava Dart is exiled, so it no longer counts as an instant. And a delirious Channeler must attack each combat. Track your types before you surveil, and know whether you want the forced attack.
Posture: Proactive First, Reactive When It Buys Damage
Your interaction is tempo, not control. Use Lightning Bolt, Unholy Heat and Lava Dart to clear the blocker or the one creature that stalls your attacks. Point Bolt at the face when that ends the game faster. Lava Dart is especially efficient against X/1s because both halves of the card can kill something.
The cantrips do the rest. Preordain, Expressive Iteration and Mishra's Bauble keep you from flooding and find the specific spell you need. Tormod's Crypt does double duty as a free artifact for Flurry and delirium, and as main-deck graveyard hate.
Treat life as a resource. Fetches, shocks, Islet and Growth all cost life. Spend it freely against slower decks, and carefully when the opponent is also attacking.
The Ideal Game
- Turn 1: Fetch and play a one-drop.
- Lead Monastery Swiftspear to start attacking immediately.
- Lead Dragon's Rage Channeler if you also have a Bauble to cast after it. That turns on surveil and puts a fetchland in the yard.
- Turn 2: Cast Cori-Steel Cutter, then a free spell such as Bauble, Growth or Crypt. That makes a Monk you can equip for free and attack with on the spot, alongside your one-drop.
- If you have no Cutter, plot Slickshot Show-Off so a later turn gets a free spell.
- Turn 3: Chain two or three spells: a cantrip, a burn spell, a plotted Show-Off, or a Lava Dart and its flashback. Each spell pumps the whole board and makes another Monk. Delirium usually comes online around here, turning Channeler into a flier.
- Turn 4 and beyond: Close the game.
- Violent Urge with delirium doubles the damage of your biggest attacker, or of a trampling Monk.
- Bolt and Lava Dart finish the opponent from range.
Closing Out Games
Count your reach every turn. Bolts in hand, Lava Darts in the graveyard with a Mountain to sacrifice, and the evasion of Show-Off, Channeler and trampling Monks often add up to lethal before the board does.
When the opponent stabilizes the ground, switch to flying and burn damage. Dump your spells into one Show-Off attack, or point everything at their face. The deck does not win long games by accident. Every turn you spend not adding damage is a turn the opponent gets to execute their plan.
Card Choices & Breakdown
Threats: Twelve Creatures and Four Engines
- Monastery Swiftspear (4): One mana, haste, prowess. It hits on turn one, and since much of the deck is noncreature spells that cost zero or one mana, it often attacks as a 3/4 or larger. Run all four because nothing else deals damage as early.
- Dragon's Rage Channeler (4): This is how you build delirium. Every noncreature spell surveils 1, so you choose what goes to the graveyard. Once delirium is on, it is a 3/3 flier for one. The drawback is that it must attack each combat, so you can't keep a delirious Channeler home to block.
- Slickshot Show-Off (4): A flying, hasty 1/2 that gains +2/+0 for each noncreature spell. Plot is what keeps it at four copies. Pay {1}{R} on a turn when you have nothing better to cast, then cast it for free later. On that later turn all your mana goes to spells, and the free Slickshot still counts toward Flurry.
- Cori-Steel Cutter (4): The engine. Your second spell each turn creates a 1/1 Monk with prowess. If you attach the Equipment to it, the Monk gets trample and haste and attacks right away. Creature removal can't hit the Cutter itself, so it keeps making threats after your creatures die. Always four.
Free Spells: Fuel for Flurry and Prowess
- Mishra's Bauble (4): A noncreature spell that costs zero mana. It triggers prowess, Channeler's surveil and Slickshot's pump. It counts toward Flurry, and it replaces itself on the next upkeep. In the graveyard it adds the artifact type for delirium. It does a lot for no card cost, which is why you run four.
- Mutagenic Growth (2): Pay 2 life, spend no mana, and get +2/+2 on a creature plus a spell toward Flurry. It saves a creature from damage-based removal and adds burst damage. You run only two because it doesn't replace itself and the life cost adds to what you already pay for fetches and shocks.
- Lava Dart (4): Two spells from one card. The flashback costs a Mountain, not mana, so you can make a second spell for Flurry with lands you no longer need. It also kills 1-toughness creatures and tokens. Your Mountains are both basics, Steam Vents, Stomping Ground and Thundering Falls. Fiery Islet is not a Mountain and can't pay the flashback.
- Tormod's Crypt (1): A zero-mana artifact spell that triggers your creatures much like Bauble. It also exiles a graveyard, which earns its main-deck slot in a field where Living End took 17 Top 8 slots and Instant Reanimator took 14 (source: MTGTop8, 2026-10-01 to 2026-10-18). When the graveyard is irrelevant, it is still a free trigger and a Flurry enabler.
Card Flow
- Preordain (4): Scry 2 and draw for one mana. It finds Cutter early and burn late, and it adds the sorcery type for delirium.
- Expressive Iteration (4): You see three cards, keep one in hand, and may play the exiled card this turn. If the exiled card is a cheap spell, casting it is your second spell, so Iteration often creates a Monk on its own. If it is a land, you hit your land drop and keep the spell. It is the main reason the deck plays blue.
Interaction and Combat Tricks
- Lightning Bolt (4): It can kill a blocker on turn one or deal the last 3 damage to the opponent. Always four.
- Unholy Heat (1): It deals 2 damage early and 6 with delirium. Use it on large creatures that survive Bolt. You run only one main because delirium isn't guaranteed early, which makes Heat weaker than Bolt in the opening turns. Two more sit in the sideboard for creature-heavy matchups.
- Violent Urge (2): First strike lets your creature win combat and pushes damage past blockers. With delirium it grants double strike. On a creature carrying Cutter, which gives trample, that ends games. You run two because you need a creature and good timing to get value from it.
Mana Base: 18 Lands
Nothing in the main deck costs more than two mana, so 18 lands is enough. Every land with a basic type in this list is a Mountain. That means each of the ten fetches can find any of them: Steam Vents, Thundering Falls, Stomping Ground or a basic Mountain. Cracked fetches also add the land type to your graveyard for delirium.
- Scalding Tarn (4), Bloodstained Mire (3), Wooded Foothills (3): In practice the three fetches work almost the same here. You run ten for the delirium land type and for consistent colors.
- Steam Vents (3): Your main blue source for Preordain and Expressive Iteration.
- Mountain (2): Fetch a basic when the shock land's 2 life matters. Basics also make good Lava Dart fodder because sacrificing one doesn't cost you blue.
- Thundering Falls (1): The surveil helps delirium, but it enters tapped. Play it or fetch it on a turn when you won't use all your mana.
- Stomping Ground (1): Your only green source. It lets you pay for Mutagenic Growth with mana instead of life, and it casts sideboard Heritage Reclamation and Pick Your Poison.
- Fiery Islet (1): An untyped dual that you can sacrifice for a card when you draw too many lands. Fetches can't find it, and it can't pay Lava Dart flashback.
The Decklist
This is the exact 75 that finished Top 4 at the MTGO Showcase Challenge on 2026-10-17 (286 players). It runs eighteen lands, twelve creatures, and thirty cheap spells, and the deck costs about $381 at TCGplayer market prices. Core slots are marked as core. Flexible slots get a one-line note on what they do for you.

| 1 | Mystical Dispute | It costs one mana against blue spells. |
| 1 | Heritage Reclamation | It is an instant-speed answer to an artifact, an enchantment, or a graveyard card, and it draws a card when used on a graveyard. |
| 1 | Pick Your Poison | It makes the opponent sacrifice an artifact, an enchantment, or a flyer, and it gets around hexproof. |
| 1 | Surgical Extraction | You can pay life for it to strip every copy of a key card. |
Reading the List
- Mountain count matters. Lava Dart flashback needs a Mountain to sacrifice. Steam Vents, Stomping Ground, Thundering Falls, and basic Mountain all qualify. Fiery Islet and the fetches do not count until they've found something.
- Delirium is built in. The main deck covers five card types: artifact, creature, instant, sorcery, and land. The ten fetches make land the easiest type to put in your graveyard.
- Green is thin on purpose. Stomping Ground is the only green source, and only Wooded Foothills and Bloodstained Mire can find it. Plan your fetches around it in games where you've brought in Heritage Reclamation or Pick Your Poison.
- Change the singletons first. The flex slots are the 1-of and 2-of noncreature spells, not the twelve creatures or the four-ofs.
Mulligan Guide
What a Keepable Hand Looks Like
This deck runs 18 lands and 42 spells, and most of those spells cost one mana or less. You need far less mana than most Modern decks, but you need the right pieces. A keepable seven has three things:
- Two lands, or one land plus real card flow. Every fetch can find Steam Vents, so any fetch counts as a blue source for Preordain and Expressive Iteration. A lone Mountain or Stomping Ground does not cast your blue spells.
- A threat or a way to find one. Your threats are the 12 creatures plus Cori-Steel Cutter, which turns every second spell in a turn into a 1/1 Monk with prowess. A hand with no threat must have cantrips to dig for one.
- Enough spells to fuel prowess and flurry. Mishra's Bauble and Mutagenic Growth (paid with 2 life) cost no mana. They count as spells for Monastery Swiftspear, Slickshot Show-Off, Dragon's Rage Channeler and the second-spell trigger on Cutter.
Ship any hand with zero or five-plus lands. Ship any hand with no threat and no cantrip. Ship any hand where pump spells like Violent Urge and Mutagenic Growth have nothing to target.
Example Hands
- Scalding Tarn, Mountain, Monastery Swiftspear, Cori-Steel Cutter, Mishra's Bauble, Lightning Bolt, Lava Dart: Snap keep. Turn one is Swiftspear. Turn two, cast Cutter, then crack in with Bauble as your second spell. The Monk token gets the Cutter attached, so it has haste and trample and attacks right away. This hand also holds Bolt and Dart for reach or removal.
- Steam Vents, Preordain, Expressive Iteration, Lightning Bolt, Unholy Heat, Lava Dart, Mutagenic Growth: Ship. It has one land and no threat. The Growth has nothing to pump, and Iteration needs a second land. Even if Preordain hits, you are a turn behind with no clock.
- Bloodstained Mire, Steam Vents, Preordain, Expressive Iteration, Mishra's Bauble, Lightning Bolt, Violent Urge: Keep. There is no threat yet, but three card-flow pieces dig into 16 threat cards. Against an unknown opponent this is fine. Against fast combo it is a weak keep, but still a keep.
- Wooded Foothills, Steam Vents, Thundering Falls, Fiery Islet, Mountain, Dragon's Rage Channeler, Preordain: Ship. Five lands in a deck that wants two leaves you flooded. The lone Channeler cannot carry the game.
- Scalding Tarn, Mountain, Slickshot Show-Off, Slickshot Show-Off, Dragon's Rage Channeler, Mutagenic Growth, Lightning Bolt: Keep. You have three threats on two lands. Turn two, you can plot one Show-Off and cast the second the following turn alongside another spell, or deploy a Show-Off directly and back it with Growth. Plotting is also your answer to sorcery-speed removal on your turn-two threat.
- Six cards: Steam Vents, Monastery Swiftspear, Cori-Steel Cutter, Preordain, Lava Dart, Mishra's Bauble: Keep. On six, a single blue-capable land with Preordain and Bauble is acceptable. Lava Dart's flashback lets you sacrifice the Vents if a burn spell would win the race. Don't sacrifice it while you're still trying to hit your second land drop.
On the Play vs. On the Draw
On the play, speed is the whole point, so ship one-landers. The exception is the six-card case above. A hand of interaction and cantrips with no threat gets worse on the play, because you're giving up the tempo edge you were handed.
On the draw, the extra card makes a one-lander with a fetch or Steam Vents plus two cantrips a reasonable keep. Removal-heavy hands also improve on the draw. Against opposing creature decks, Lightning Bolt and Unholy Heat on their first threat buy back the tempo you lost.
Adjusting for Matchups
- Broodscale Bloodchief: This was the most-represented archetype in the window, with 82 of 460 Top 8 slots (source: MTGTop8, 2026-10-01 to 2026-10-18). Value a fast clock over a reactive hand. Keep the hands that are threat-plus-Cutter, and ship slow cantrip piles.
- UR Cutter Prowess mirror and other aggro (Boros Aggro, Rakdos Delirium, 5c Domain Aggro): Removal counts as half your keep. A hand with one threat and two burn spells beats a hand with three threats and no answers. Expect cheap removal post-board: Unholy Heat appeared in all 30 UR Cutter Prowess Top 8 sideboards (source: MTGTop8, 2026-10-01 to 2026-10-18). Hands built on multiple cheap threats are more resilient than a single Cutter.
- Combo (Scepter Chant, Ruby Storm, Devoted Combo): Keep the fastest hand you're offered. Post-board, a hand with Spell Pierce or Consign to Memory plus a two-turn clock is ideal. Consign counters triggered abilities and colorless spells. A pile of interaction with no clock is not ideal.
- Graveyard decks (Living End, Instant Reanimator): Pressure still matters most. Post-board, a hand with Tormod's Crypt or Surgical Extraction plus threats is premium. Crypt costs nothing, so it never weakens your curve.
- Control (Dimir Control, UW Control): Threat density beats everything. Keep hands with two or more threats, and favor Slickshot Show-Off plots and Cori-Steel Cutter over hands that need one creature to survive.
Sequencing & Key Lines
Turn 1: Pick the Right Lead
Your turn-one choice decides how much damage the next two turns deal. Use these defaults:
- Lead Monastery Swiftspear when your hand has burn and cheap spells you'll cast on turns two and three. Haste and prowess mean it deals damage right away, and each later spell adds more.
- Lead Dragon's Rage Channeler when your hand is mostly cantrips (Preordain, Mishra's Bauble, Expressive Iteration). It needs time to surveil its way to delirium, so it gains the most from coming down first.
- Play Thundering Falls on turn one if you have no one-drop to cast. The tapped land costs you nothing that turn, and the surveil helps fill your graveyard.
Every fetchland in the list can find Steam Vents, Thundering Falls, or Mountain. Fetch for the basic Mountain when your life total matters, such as against aggressive decks or when you plan to pay life for Mutagenic Growth. Crack fetches early, because the land in your graveyard is an easy delirium type.
Don't fire Mishra's Bauble on turn one just because it's free. A Bauble held until turn two becomes your free second spell for Cori-Steel Cutter.
Turn 2: The Cutter Turn
Sequencing Cori-Steel Cutter has one rule: Cutter must already be on the battlefield when you cast your second spell. If you cast Bauble first and Cutter second, Cutter is your second spell, but it isn't on the battlefield yet, so there is no trigger.
The standard line:
- Cast Cori-Steel Cutter and let it resolve.
- Cast a free spell: Mishra's Bauble, Tormod's Crypt, or Mutagenic Growth paid with life.
- The second spell creates a Monk token. Attach Cutter to it. The token now has haste and trample, so it attacks this turn alongside your one-drop.
If you have no Cutter, choose between casting Slickshot Show-Off now and plotting it.
- Hard-cast it to attack immediately with flying and haste.
- Plot it if you want a bigger turn three. Plotting is not casting a spell, so it doesn't trigger flurry or prowess. On turn three, though, you cast it for free. That free cast counts as a spell for Cutter's flurry, and it leaves all your mana open for noncreature spells to pump it.
Turn 3 and Beyond: Count Your Spells
Flurry triggers once per turn, on the second spell. Any spells after that only feed prowess, Show-Off, and Channeler. Plan each turn around which two spells start the chain, then spend the rest on damage.
- "Each turn" includes your opponent's turn. Casting Lightning Bolt and then flashing back Lava Dart at their end step makes a Monk at instant speed. Attaching Cutter through the trigger is not an equip activation, so it works at instant speed too. You give away nothing during your own main phase.
- Cast Expressive Iteration before your land drop. If a land gets exiled, you can still play it.
- Lava Dart flashback needs a Mountain. Steam Vents, Stomping Ground, Thundering Falls, and Mountain qualify. Fiery Islet and the fetchlands do not. Never sacrifice your only blue source while Preordain or Iteration is still in your hand.
- Late in the game, use Fiery Islet's draw ability when you have more lands than you need and nothing better to spend mana on.
Delirium Management
Delirium needs four card types in your graveyard. Your available types are land, artifact, instant, sorcery, and creature. Track the ones that silently fail to arrive:
- A flashed-back Lava Dart exiles itself.
- Expressive Iteration exiles one card and bottoms another, so neither reaches your graveyard. The Iteration itself does.
- Mishra's Bauble and Tormod's Crypt are your most reliable artifact types. Point Crypt at the opponent's graveyard, not yours.
Delirium has a cost: a delirious Dragon's Rage Channeler must attack each combat if able. Before you surveil that fourth type into the graveyard, check whether a forced attack into their board is acceptable. Holding delirium back for a turn is sometimes correct. The reward is real, though. Delirium turns Unholy Heat into 6 damage and gives Violent Urge double strike.
Hold Your Tricks
Violent Urge and Mutagenic Growth do the most after blockers are declared, not in your main phase.
- Delirious Urge on a Cutter-equipped creature gives you double strike and trample, which is often lethal through a chump blocker.
- Growth costs no mana, so you can hold it up every turn.
- Every trick is also a noncreature spell. It pumps each prowess creature you control and Show-Off, not only its target.
Playing Around Interaction
- Damage-based removal: respond with Mutagenic Growth or any instant to trigger prowess and push toughness out of range. Pay the 2 life without hesitating when it saves a threat.
- Removal-heavy opponents: deploy one threat at a time and keep a spell or two in hand. Cori-Steel Cutter keeps making bodies as long as you keep casting spells. That makes it your most resilient threat, so protect it by not dumping your hand into one Monk.
- Artifact hate: Cutter is an artifact. Against opponents who can answer artifacts, make sure creature threats are already applying pressure before you rely on Cutter.
- Post-board mirror: Meltdown appeared in 22 of 30 UR Cutter Prowess Top 8 sideboards (source: MTGTop8, 2026-10-01 to 2026-10-18). At X=2 it destroys Cutter, Bauble, and Crypt together. Against a mirror with open mana after sideboarding, activate Baubles promptly instead of stockpiling them. Make sure Cutter has already created Monks that will survive it.
Matchup Matrix
| Matchup | Verdict | What decides it |
|---|---|---|
| Broodscale Bloodchief | Even | Killing their early creatures before their combo or Eldrazi ramp comes online |
| UR Cutter Prowess (mirror) | Even | Who keeps a Cori-Steel Cutter on the table |
| Rakdos Delirium | Even | Threat density against their removal, and graveyard control |
| Boros Aggro | Even | Tempo and life totals, since your burn lines up well against their small creatures |
| Scepter Chant | Even | Damage dealt before their lock assembles |
| Pinnacle Affinity | Even | Racing their artifact board, then Meltdown after sideboarding |
| Big mana (Tron, ramp) | Favored | A fast clock against a slow setup |
| Graveyard combo | Even | Timing Tormod's Crypt and countering their key trigger |
| Blue control | Even | Overloading counters and sweepers with cheap, card-flow-backed threats |
| Fast non-graveyard combo | Unfavored | Whether you can pressure them and hold interaction at once |
Broodscale Bloodchief
This is the deck you will see most. It took 82 of 460 Top 8 slots (source: MTGTop8, 2026-10-01 to 2026-10-18). Every one of those lists ran 4 Urza's Saga and 4 Eldrazi Temple (source: MTGTop8 deck exports, 2026-10-01 to 2026-10-18). It has two ways to beat you: a creature-based combo and a colorless ramp plan into huge threats.
Your plan is to be the beatdown and to treat every early creature they play as a must-answer. Lava Dart picks off X/1s. Its flashback lets you answer a second one without spending a card. Use Lightning Bolt and Unholy Heat on anything bigger.
After sideboarding, these cards improve the matchup:
- Obsidian Charmaw gets cheaper for each land they control that could produce {C}, and its enters trigger destroys a nonbasic land.
- Consign to Memory counters colorless spells, which covers their top-end Eldrazi.
UR Cutter Prowess (Mirror)
Cori-Steel Cutter decides this matchup, and the opposing Cutter is red, not colorless. That means Consign to Memory cannot counter the Cutter itself. It can only counter its Flurry trigger.
- Spend your burn on Dragon's Rage Channeler and Slickshot Show-Off early, before delirium or a pump spell makes them out of reach.
- Bring in Meltdown with X=2, which handles Cutter and Baubles in one card.
- Expect the same answers from them. Meltdown appeared in 22 of 30 UR Cutter Prowess Top 8 sideboards, and Unholy Heat appeared in all 30 (source: MTGTop8 deck exports, 2026-10-01 to 2026-10-18).
- Don't overextend Monk tokens into a known Meltdown. Keep an unequipped creature in hand as a reload.
Rakdos Delirium
This is a removal-dense midrange deck that also builds a graveyard. Two things help you here:
- Threat count. Cori-Steel Cutter keeps producing bodies after your creatures die, and Expressive Iteration keeps your hand full.
- Graveyard control. Tormod's Crypt can wipe their graveyard just as their delirium turns on. Fire it when it costs them a turn of value, not as soon as you draw it.
Avoid casting a pump spell in response to their removal unless it actually saves the creature. Card advantage matters more here than a few points of damage.
Boros Aggro
This is a straight race, and you have the cheaper interaction. Spend your early turns killing their creatures with Lava Dart and Lightning Bolt. Monastery Swiftspear and Monk tokens can hold the ground while Slickshot Show-Off attacks in the air.
Violent Urge does double duty. It gives first strike, which wins combat on either side of the table. Use it to protect your creature in a block, not only to push damage.
Scepter Chant
This is a lock deck built around a colorless artifact. Your plan:
- Get damage in fast, and plot Slickshot Show-Off early so you have a hasty threat ready after a lock piece lands.
- After sideboarding, Consign to Memory counters the artifact as it is cast.
- Spell Pierce catches the noncreature spells that set up the lock.
- Meltdown answers the artifact once it resolves.
Keep a counterspell up rather than tapping out for a marginal threat.
Pinnacle Affinity
Before sideboarding, you race and burn their key creatures. After sideboarding, this matchup is where Meltdown does the most work. Choose X to wipe their cheap artifacts while keeping your own losses manageable, and cast it before you deploy Cori-Steel Cutter.
Pick Your Poison gives you a second artifact answer. Its flier mode also catches flying threats.
Big Mana
Tron and ramp decks give you time, and you should use it to kill them before their payoffs matter. Keep any two-threat hand.
Obsidian Charmaw punishes colorless-producing land bases. Its enters trigger destroys a nonbasic land, which also slows a ramp deck. Consign to Memory counters colorless top-end.
Graveyard Combo
This covers Living End and Instant Reanimator. Main-deck Tormod's Crypt is your best card in the matchup. Hold it with mana open as a response to their key spell rather than cracking it early.
After sideboarding, add Consign to Memory for their triggered abilities and Surgical Extraction to exile a combo piece outright. Remember that your own delirium suffers whenever you exile graveyards, so plan which yard you are clearing.
Blue Control
Here is how to beat counters and sweepers:
- Play one threat at a time. Plot Slickshot Show-Off so you can deploy two threats in one turn later.
- Cast Expressive Iteration on their end step-adjacent windows... no — it is a sorcery, so cast it on your own turn when they are tapped low, which also lets you play the exiled card immediately.
- Bring in Spell Pierce and Mystical Dispute, which costs only {U} when it targets a blue spell.
- Point Lightning Bolt at their face late in the game.
Fast Combo
Against Ruby Storm and Devoted-style combo, you can't interact much before sideboarding. Mulligan toward hands that apply fast pressure.
After sideboarding, keep Spell Pierce up on the turn they are likely to go off. Use Consign to Memory against their combo triggers or colorless pieces.
Sideboard / Tech Guide
Your fifteen breaks into three jobs: artifact and enchantment hate (Meltdown, Pick Your Poison, Heritage Reclamation), stack and graveyard interaction (Spell Pierce, Mystical Dispute, Consign to Memory, Surgical Extraction), and extra creature answers or threats (Unholy Heat, Obsidian Charmaw). Your usual cuts are Tormod's Crypt, Violent Urge, and Mutagenic Growth. They are the narrowest maindeck slots once you know what the opponent is doing.
Summary
Broodscale Bloodchief
This is the deck you will meet most. It took 82 of 460 Top 8 slots (source: MTGTop8, 2026-10-01 to 2026-10-18). Every one of those lists ran 4 Urza's Saga, and Grafdigger's Cage showed up in all 82 sideboards, with Trinisphere in 79 (source: MTGTop8 deck exports, 2026-10-01 to 2026-10-18).
- Saga is an enchantment. That makes the enchantment modes on Pick Your Poison and Heritage Reclamation live.
- Meltdown answers their artifacts and their sideboard artifacts at the same time.
- Set X to the lowest number that cleans up their board. Any X of 2 or more also destroys your own Cori-Steel Cutter, and every X destroys your Mishra's Baubles. Crack your Baubles before you cast it.
Pinnacle Affinity
Use the same package as against Broodscale. Pick Your Poison gives you a choice: the artifact mode, or the flying-creature mode if a flyer is the real clock.
The plan with Meltdown is to stop deploying Cori-Steel Cutter the turn before you cast it. Keep the Cutter in hand, Meltdown on a big X, then land Cutter afterward onto an empty board.
Living End and Instant Reanimator
Consign to Memory counters triggered abilities, and a cascade trigger is a triggered ability. Replicate lets you answer more than one trigger in a single turn. Against Reanimator, aim it at whatever trigger or colorless spell actually pays them off.
Keep Tormod's Crypt in for both matchups:
- Leave it uncracked until they commit, so they can't play around it.
- Exile their graveyard in response to the payoff.
- Follow up with Surgical Extraction on the key card to strip the remaining copies from their hand and library.
Against Reanimator only, keep the maindeck Unholy Heat and cut a Lava Dart instead. A delirium-powered Heat is your out to a creature that sticks.
Spell combo
Ruby Storm and Scepter Chant both rely on noncreature spells. Spell Pierce hits those spells, and it is best when they tap low to go off. Mystical Dispute costs one mana against a blue spell and three otherwise, so check their colors before you count it as cheap interaction.
Against Scepter Chant, the Scepter is an artifact. Pick Your Poison and Heritage Reclamation are reasonable additions over the fourth Consign.
Control
Their plan is to trade one-for-one and take over the late game. Your Spell Pierce protects a turn where you cast Expressive Iteration or a burn spell to the face. Cut Violent Urge, since it is a pump spell that a single removal spell in response blanks.
UrzaTron
Obsidian Charmaw costs one less for each opposing land that could produce {C}. Its enter trigger also destroys a nonbasic land. Against a big-mana land base, it is often cheap enough to cast early and set them back a turn. That makes it both a tempo play and a fast evasive clock.
Aggro and mirrors
In these matchups your life total is a resource, so trim the life-paid Mutagenic Growth and add removal.
- Removal: Pick Your Poison on flyers handles opposing Slickshot Show-Offs. That card appeared in 25 of 30 UR Cutter Prowess Top 8 lists (source: MTGTop8 deck exports, 2026-10-01 to 2026-10-18).
- Expect Meltdown in the mirror: it was in 22 of those 30 sideboards (same source and dates). Don't stack multiple Cori-Steel Cutters into an open red mana after sideboarding.
- Cutter can't be Consigned: it costs {1}{R}, so it is not a colorless spell and Consign to Memory can't counter it. Consign can still counter the Flurry trigger, but that alone rarely justifies the slot.
Green splash discipline
Heritage Reclamation and Pick Your Poison need {G}, and your only green source is one Stomping Ground. All nine fetchlands can find it, because it is a Mountain. When you have boarded in green cards:
- Make Stomping Ground your first fetch target.
- Pay the 2 life if you need it untapped.
- Pay for Mutagenic Growth with life rather than tapping your only green source.
Never bring in both green cards plus Surgical Extraction against aggro. Too many life-taxed and off-color cards will lose you races.
Tech Choices & Variations
The 60 has a fixed core and a short list of slots you can move. The fixed core is the four-ofs: the cheap creatures, Cori-Steel Cutter, the cantrips, and the burn. Six main-deck cards and the last few lands are where you adjust. Every swap below uses cards already in the 75, so you can retune between rounds of a weekend without buying anything.
Main-Deck Flex Slots
| Slot | Job in the list | Swap toward | What you give up |
|---|---|---|---|
| 1 Unholy Heat | Cheap creature or planeswalker removal that scales with delirium | A second or third copy from the board against creature decks | A pump spell or trigger enabler, which weakens your Flurry turns |
| 1 Tormod's Crypt | A free spell plus game-one graveyard hate | Spell Pierce against spell-heavy fields | A zero-mana prowess trigger and a cheap artifact for delirium |
| 2 Mutagenic Growth | A free pump that also counts as a spell for Flurry | A third Violent Urge | Zero-mana double-spell turns |
| 2 Violent Urge | Combat trick that wins through blockers, with double strike under delirium | A third Mutagenic Growth | Evasion through blockers and burst damage |
Tormod's Crypt is more than a sideboard card in the main. It is a noncreature spell that costs nothing, so it triggers prowess, gives Dragon's Rage Channeler a surveil, and pumps Slickshot Show-Off. It can also be the first half of a Flurry turn at no mana. Once you sacrifice it, it puts an artifact in your graveyard toward delirium. Cut it only when you expect almost no graveyard decks. In that case the slot is better spent on Spell Pierce than on another threat.
The pump split is the main dial. Mutagenic Growth costs 2 life instead of mana. That lets you cast two spells for {R} and trigger Cori-Steel Cutter on turns when you have almost no mana to spare. It also takes your creature out of range of 2- and 3-damage removal. Violent Urge costs a red mana, but first strike lets you attack into larger blockers. With delirium and a trample-granting Cutter attached, double strike ends games out of nowhere. Lean toward Growth when opponents mostly try to kill your creatures with damage. Lean toward Urge when they mostly put big bodies in front of you. Against fast aggro, the life payment adds up, so Urge is the safer pump there.
The Mana Base
- Stomping Ground exists to find green for Heritage Reclamation and Pick Your Poison, and to let you pay {G} for Growth. If you board out the green cards, the slot could be a fourth Steam Vents. That costs you your green source for those sideboard cards.
- Two Mountain let you fetch without paying shock life. They also hold up against land destruction aimed at nonbasics, and you can sacrifice one to flash back Lava Dart without losing a dual. Every land in the deck except Fiery Islet can find or be a Mountain, so Dart's flashback is rarely blocked.
- Thundering Falls surveils toward delirium but enters tapped. Fiery Islet costs 1 life per tap and turns into a card late. In faster fields, replacing the Falls with an untapped land is a reasonable tempo upgrade.
Sideboard Flex
- Obsidian Charmaw costs less for each opposing land that could produce {C}. It is strongest against decks built on colorless lands and nearly uncastable otherwise. Two copies is the ceiling unless your room is full of those decks.
- Mystical Dispute vs. a third Spell Pierce: Dispute costs one mana against blue spells and can hit creature spells. Pierce is better against noncreature spells from non-blue combo decks.
- Meltdown: choose X carefully. At X=0 it kills your own Mishra's Bauble and Tormod's Crypt. At X=2 it also kills your Cori-Steel Cutter. Against artifact decks, you can usually give those up.
- Consign to Memory counters triggered abilities and colorless spells, and replicate lets one card stop several of them. Three copies is the right number in a field full of triggers. Trim to two if graveyard and artifact decks are rare.
- Heritage Reclamation / Pick Your Poison / Surgical Extraction are single copies you can swap as needed. Reclamation replaces itself with a draw. Poison can force the sacrifice of a flying creature. Extraction answers a single card your opponent relies on.
Tuning for Your Field
Broodscale Bloodchief took 82 of 460 Top 8 slots across 59 events (source: MTGTop8, 2026-10-01 to 2026-10-18). Expect it at any sizable event and keep your full Meltdown, Consign to Memory, and Obsidian Charmaw package. UR Cutter Prowess held 30 slots over the same span (source: MTGTop8, 2026-10-01 to 2026-10-18), so prepare for near-mirrors. In those games, the main Unholy Heat and Violent Urge carry their weight, and Consign can counter opposing Flurry triggers.
- Graveyard-heavy room (Living End and Instant Reanimator took 17 and 14 slots; source: MTGTop8, 2026-10-01 to 2026-10-18): keep Tormod's Crypt in the main without hesitation.
- Spell-combo room (Scepter Chant, Devoted Combo, Ruby Storm): move Spell Pierce in for Unholy Heat or a pump spell.
- Creature-aggro room (Boros Aggro, 5c Domain Aggro): bring in more Unholy Heat and shift the pump split toward Violent Urge.
Budget Options
Where the Money Likely Goes
The full list runs about $381 at TCGplayer market prices. Check current prices yourself before buying. In a list like this, most of that total likely sits in the mana base: ten fetchlands (Scalding Tarn, Wooded Foothills, Bloodstained Mire) and four shocklands (Steam Vents, Stomping Ground). The rest is spread across the engine pieces: Cori-Steel Cutter, Dragon's Rage Channeler, Slickshot Show-Off, Expressive Iteration and the playsets of cheap spells. That split is good news for a budget build. The lands are where you can cut and still play the real deck.
What You Cannot Cut
The closely related UR Cutter Prowess Top 8 lists all ran 4 Cori-Steel Cutter, 4 Lightning Bolt, 4 Preordain, 4 Lava Dart and 4 Mishra's Bauble (source: MTGTop8, 2026-10-01 to 2026-10-18). Treat those as the price of entry. The reason is the Flurry trigger on Cutter, which fires when you cast your second spell each turn. Zero-mana Mishra's Bauble, a flashed-back Lava Dart and a life-paid Mutagenic Growth are what make two-spell turns cheap.
Without Cutter, you are playing a different, weaker deck. Dragon's Rage Channeler is close behind, because surveil on every noncreature spell is how you reach delirium.
Budget Swaps and What They Cost You
| Cut | Replace With | What You Give Up |
|---|---|---|
| 3 Wooded Foothills, 3 Bloodstained Mire | A split of basic Mountain and basic Island | A land card in your graveyard on demand, which is your easiest delirium type. You also lose fetching a Mountain to rebuy for Lava Dart flashback. |
| Stomping Ground | Basic Mountain | Your only green source. Heritage Reclamation and Pick Your Poison must leave the sideboard with it. |
| Heritage Reclamation, Pick Your Poison | A 3rd Meltdown and a 2nd Surgical Extraction | Instant-speed enchantment removal, the flying-creature mode, and the cantrip. Surgical Extraction stays castable for 2 life. |
| Some Steam Vents | Basics | Untapped dual mana. Casting Expressive Iteration alongside a red one-drop gets harder. |
| Expressive Iteration (last resort) | 2nd Unholy Heat and 3rd Violent Urge | Your card advantage engine in grindy games. Preordain still supplies the sorcery type for delirium. |
The fetchland cut is the one that hurts gameplay. Delirium needs four card types in your graveyard. Lands are one of the most reliable types because you choose when to crack a fetch. It powers Dragon's Rage Channeler, Unholy Heat and Violent Urge.
A basic-heavy build still has two ways to put lands in the yard:
- Fiery Islet can sacrifice itself to draw a card.
- Thundering Falls surveils when it enters, letting you bin a land off the top.
Keep both. Expect delirium to come online a turn later in some games, and value Tormod's Crypt and Mishra's Bauble even more as artifact-type enablers.
Mind your blue count. Only Scalding Tarn can find a basic Island. Wooded Foothills and Bloodstained Mire find Mountains only. If you cut Steam Vents too, every Mire and Foothills is effectively a red source. Blue spells like Preordain, Spell Pierce and Consign to Memory then depend on your few true blue lands.
Two rules for a budget mana base:
- When you trim fetches, cut Foothills and Mire before Tarn.
- Make sure the basics you add include enough Islands.
Upgrade Path
- Engine first. Buy 4 Cori-Steel Cutter, 4 Dragon's Rage Channeler, 4 Slickshot Show-Off, 4 Monastery Swiftspear and the full cantrip and burn suite. A basic-heavy deck with these cards plays like the real list in most early turns.
- Expressive Iteration. If you skipped it, this is your next pickup. It is the card that wins long games against interactive decks.
- Scalding Tarn. It is the most flexible fetch here, since it finds Island or Mountain and fixes your blue count.
- Steam Vents. These replace your basics and make the double-colored turns smooth.
- Bloodstained Mire and Wooded Foothills. These restore full delirium speed and Mountain access.
- Stomping Ground, then the green sideboard. Buy these last. They only matter in the matchups where Heritage Reclamation or Pick Your Poison comes in. Mutagenic Growth already works off 2 life without them.
Follow this order and every purchase raises your win rate in actual games, rather than just raising the deck's value. You will be on the tournament list well before the mana base is finished.
Common Mistakes
1. Cracking Fetches After You've Already Looked at Your Library
Mishra's Bauble lets you see the top card of your library, and Preordain arranges the top two. Crack a fetch afterward and you shuffle away everything you just learned or set up. Cast your Scalding Tarn, Wooded Foothills, or Bloodstained Mire before you scry, Bauble yourself, or cast Expressive Iteration. The one exception is when the top card is bad and a shuffle is the cleanest way to get rid of it. If a fetch has to sit uncracked for a turn, point the Bauble at your opponent instead, so the look isn't wasted.
2. Fetching Away the Mountains You Need for Lava Dart
The flashback cost on Lava Dart is sacrificing a Mountain. The Mountains in this list are the two basic Mountains, Steam Vents, Stomping Ground, and Thundering Falls. Fiery Islet and the fetches don't count. If you fetch out every Mountain-typed land early, you can strand the flashback. Count your Mountains before each fetch.
- Fetch a basic Mountain when you have blue already and no shock payment to spare.
- Fetch Steam Vents when you need both colors right now.
When you flash back Dart, sacrifice whichever Mountain costs you the least: a tapped land you're done with this turn, or the dual whose second color you no longer need.
3. Wasting the Flurry Trigger
Cori-Steel Cutter triggers only on your second spell each turn, and only if it's already on the battlefield when that spell is cast. Two errors come up constantly:
- Spreading cheap spells across turns. If you cast one spell a turn, Cutter does nothing.
- Burning free spells on a turn that already triggered. Mishra's Bauble costs zero, and Mutagenic Growth can be paid with 2 life. They're your best ways to reach "second spell" on a tight mana turn. Save them for that.
Also, a plotted Slickshot Show-Off cast from exile is still a spell cast. That makes it a free flurry enabler on a later turn.
4. Feeding Delirium Badly
Dragon's Rage Channeler, Unholy Heat, and Violent Urge all want four card types in your graveyard. Each type comes from specific cards:
- Land: fetches and a sacrificed Fiery Islet.
- Artifact: spent Mishra's Bauble or a sacrificed Tormod's Crypt.
- Instant and sorcery: your cheap spells.
- Creature: usually only from surveil.
Three points of leakage get missed. Flashing back Lava Dart exiles it, so if it was your only instant in the graveyard, you just lost a type. The card Expressive Iteration exiles never reaches the graveyard. And a Tormod's Crypt that never gets used never becomes an artifact in your yard. Check the type count before every surveil, flashback, and Crypt activation. If you're one type short, the surveil decision is easy: bin the card of the missing type.
5. Firing Unholy Heat for 2 When It Could Deal 6
This follows from mistake 4 but costs games on its own. If the target survives 2 damage and delirium is one land drop or one cantrip away, wait. Spend the turn assembling types, then kill the creature for real. The reverse also matters: if 2 damage kills the target now, don't hold Unholy Heat chasing a bigger number you don't need.
6. Casting Pump Spells in Your Main Phase
Mutagenic Growth and Violent Urge are instants. Prowess on Monastery Swiftspear, the trigger on Slickshot Show-Off, and the surveil on Dragon's Rage Channeler all fire on cast, at any point in the turn. Casting them precombat just gives your opponent information for their blocks.
Attack first. Then cast pump after blockers are declared, or in response to removal, where +2/+2 can save a creature from damage-based removal. A delirium Violent Urge grants double strike, so cast every other pump and prowess spell before first-strike damage. That way the bonus counts twice.
7. Playing Your Land Before Expressive Iteration
Expressive Iteration lets you play the exiled card this turn, and that includes a land. If you've already made your land drop, an exiled land is simply gone. On turns when your land drop isn't needed to cast Iteration, hold it until you've seen the three cards. Keep spare mana open too, so you can cast an exiled spell instead of losing it.
8. Bleeding Out on Your Own Mana
This deck charges you life constantly:
- Every fetch costs 1.
- Each shock land costs 2 if you want it untapped.
- Fiery Islet costs 1 per tap.
- Mutagenic Growth costs 2.
Against other aggressive decks, that adds up fast. Ask whether you need the untapped land this turn. If your only play is a one-drop, let the shock enter tapped. Against burn and aggro, treat Thundering Falls as a turn-one or quiet-turn land. Fetch basics when the extra color isn't needed yet.
Tournament Prep & Final Notes
What to Practice Before the Event
This deck rewards repetition more than theory. Three skills decide close games, so drill them until they're automatic:
- Delirium counting. Track your graveyard by type, not by card count. Your available types are land (cracked fetches, a sacrificed Fiery Islet, the Mountain you sacrifice to Lava Dart), artifact (Mishra's Bauble, Tormod's Crypt, a dead Cori-Steel Cutter), instant, sorcery (Preordain, Expressive Iteration), and creature. Before every surveil off Dragon's Rage Channeler or Thundering Falls, know which type you're missing and bin accordingly.
- Flurry math. Count spells per turn out loud in practice. Know how many tokens you can make with the mana you have, and which zero-mana spells get you there.
- Life management. Shocklands, fetches, Fiery Islet, and Phyrexian-mana Mutagenic Growth all cost life. Against aggressive decks and the mirror, you can lose a race you were winning on board. Practice taking shocks only when the untapped land changes what you can do this turn.
Rules Interactions to Know Cold
- Free spells are still spells. Mishra's Bauble and Mutagenic Growth paid with life each count as a spell for Flurry. Each also counts as a noncreature spell for prowess, Slickshot Show-Off, and Dragon's Rage Channeler's surveil. Bauble into Growth makes a Monk token for zero mana.
- Flurry counts any spell, on any turn. Creature spells count, including a plotted Slickshot Show-Off cast for free. Your second spell on your opponent's turn also creates a token. Each Cori-Steel Cutter triggers separately, so two Cutters make two tokens.
- The free attach grants haste. When Flurry creates a token, you may attach the Cutter to it without paying equip. A token made in your precombat main phase attacks immediately as a 2/2 trampling haste prowess creature.
- Lava Dart flashback needs a Mountain. Steam Vents, Stomping Ground, Thundering Falls, and basic Mountain all qualify. Fiery Islet and the fetchlands do not. Flashback exiles the Dart, so if it's your only instant in the graveyard, you just lost a delirium type. The sacrificed land replaces a land type, not an instant.
- Expressive Iteration's exiled card is "play," not "cast." If you haven't made your land drop, an exiled land is playable this turn. Anything left in exile at end of turn is gone.
- Plot is sorcery-speed on both ends. Plot Slickshot Show-Off on a turn with spare mana. Later, cast it free in your main phase to fuel Flurry while your mana goes to other spells.
- Bauble's draw is delayed. Crack it on your opponent's turn and you draw in your upkeep. Crack it on your turn and the card arrives in their upkeep. Either way, you can look at your own top card before a surveil or Preordain decision.
- Delirium Channeler must attack. Once it's a 3/3 flier, it attacks each combat if able. Plan blocks and races around that.
- Tormod's Crypt targets a player. On MTGO, confirm the target before you exile your own delirium graveyard.
Metagame Homework
Broodscale Bloodchief is the deck to prepare for. It took 82 of 460 Top 8 slots across 59 events (source: MTGTop8, 2026-10-01 to 2026-10-18). Its sideboard carries Grafdigger's Cage in all 82 of those lists and Trinisphere in 79 (source: MTGTop8 deck exports, 2026-10-01 to 2026-10-18). Know exactly how your post-board games change against both cards before round one. Haywire Mite appears in 78 of the 82 lists (source: MTGTop8 deck exports, 2026-10-01 to 2026-10-18), so expect your artifacts to be pressured.
Next, get mirror reps. UR Cutter Prowess held 30 Top 8 slots (source: MTGTop8, 2026-10-01 to 2026-10-18). At this list's own event, UR Cutter Prowess finished 2nd and Top 4 alongside this UR Aggro Top 4 (source: MTGTop8, 2026-10-17). Rakdos Delirium, with 29 slots (source: MTGTop8, 2026-10-01 to 2026-10-18), is the third matchup worth dedicated testing.
The card pool is stable for now. The 2026-10-12 announcement made no Modern changes, and the next announcement is set for 2026-11-30 (source: Wizards of the Coast, accessed 2026-10-19).
Time Management
The deck closes games quickly, but it creates a lot of small decisions. Ten fetchlands, surveils, Iteration splits, and Bauble cracks all add up, and MTGO's chess clock punishes hesitation more than misplays.
- Pre-plan your turn during your opponent's turn.
- Crack fetches as soon as you know which land you want. Waiting gains you nothing when no card in your deck cares about an uncracked fetch.
- Decide each surveil by asking one question: "Does this card or this type matter more?"
Final Assessment
This is a tight, proactive list with almost no dead draws. Twelve one-mana threats and Slickshot Show-Off pair with a dense suite of cheap spells that all fuel Flurry, prowess, and delirium at once.
A few slots are deliberate concessions:
- The lone main-deck Unholy Heat trades interaction for pressure.
- The single main-deck Tormod's Crypt gives graveyard insurance that doubles as a free artifact type.
- Stomping Ground and Wooded Foothills support green Phyrexian mana on Mutagenic Growth and the green sideboard cards, Heritage Reclamation and Pick Your Poison.
The real vulnerabilities are artifact hate aimed at Cori-Steel Cutter and self-inflicted life loss against faster decks. Meltdown, Consign to Memory, and careful shock discipline are your answers.
If you've drilled the counting skills above, this list punishes stumbles and converts small edges into wins. The Top 4 result reflects that.
