Archetype Overview

Greasefang Parhelion is an Abzan graveyard deck built around one interaction: Greasefang, Okiba Boss returns a Vehicle from your graveyard to the battlefield at the beginning of combat, gives it haste, and sends it back to your hand at your next end step. The Vehicle you most want to return is Parhelion II, an eight-mana card the deck almost never casts. If you discard or mill it on turns one and two and land Greasefang on turn three, Greasefang's 4 power pays Crew 4 by itself. Parhelion swings in as a 5/5 flier with first strike and creates two attacking 4/4 flying Angels. That is thirteen power in the air, two turns before most decks expect to face a real threat.

The list here took Top 4 at an MTGO Challenge 32 on 2026-10-22 (40 players), played by MTGO user jarold9. The build is more than a one-trick combo list. Every enabler doubles as a fair card, and the Vehicle suite gives Greasefang more than one target.

The Plan

You need two things: a Vehicle in the graveyard and Greasefang on the battlefield at the start of combat. The deck has many ways to supply each half.

• Getting Parhelion into the yard: Professor of Symbology learns by discarding a card to draw a card. Formidable Speaker discards a card and tutors any creature. Something Worth Saving mills four at instant speed. Overlord of the Balemurk cast for its impending cost of {1}{B} mills four on turn two. Bitter Triumph and Collective Brutality both let you discard as part of the cost while removing a blocker or a threat.
• Finding or rebuying Greasefang: Speaker tutors it. Overlord and Takenuma, Abandoned Mire return it from the graveyard to your hand. Yathan Roadwatcher and Emptiness go further and put it straight onto the battlefield, since Greasefang has mana value 3. Emptiness does this even when cast for its evoke cost, as long as {W}{W} was spent.
• Protecting the turn: Thoughtseize strips removal before you commit. Jennifer Walters stops your opponents from casting spells during your turn, which shuts off instant-speed answers in the window where Greasefang has to survive.

Why the Plan Is Strong

The deck's strength is redundancy across three Vehicles, not the speed of the Parhelion kill alone.

Thundering Broodwagon is a repeatable engine. Cycling it for {2} draws a card and puts it in the graveyard. Greasefang then returns it, and its enters trigger destroys an opposing nonland permanent with mana value 4 or less. It attacks as a hasty 6/5 with menace and reach, with Greasefang crewing it, and goes back to your hand at end step. Next turn you can cycle it again and repeat the loop. Against fair decks, that is a removal spell, a card, and six damage every turn for two mana.

Esika's Chariot works as a threat on its own and with Greasefang. Hard-cast on turn four, it leaves two 2/2 Cats that can crew it or Parhelion. Returned by Greasefang, it makes two Cats again before bouncing back to your hand to be recast. Hitting either Vehicle with a mill effect is never a dead outcome.

Your enablers are good cards when the combo isn't on. Speaker can fetch Roadwatcher or Emptiness for a reanimation turn, and its untap ability can untap a land for extra mana. Something Worth Saving finds lands or permanents. Bitter Triumph is unconditional creature and planeswalker removal at instant speed. Boseiju, Who Endures answers artifacts, enchantments and nonbasic lands from a land slot. Because of this overlap, a hand without Parhelion can still play a normal game while digging toward the kill.

The mana supports the plan. Twenty-three lands, including four Multiversal Passage that can name whichever basic type the hand needs, make the early {W}{B} for Greasefang reliable. They also leave room for {B}{B}{G}{G} Broodwagon turns later.

Where It's Vulnerable

The deck depends on its graveyard and on one 4/3 surviving to combat. Graveyard hate that exiles Parhelion, or removal on Greasefang during your main phase, can turn a turn-three kill into a turn-five grind. Artifact removal punishes you for crewing. The answers are built into the list. Thoughtseize clears the path, Jennifer Walters closes the instant-speed window on your turn, and the reanimation creatures rebuy Greasefang. Still, expect to play through disruption rather than around it every game.

Who Should Pick It Up

This deck rewards players who enjoy branching decisions:

• Which card to discard to Professor.
• Whether to mill with Something Worth Saving now or hold it as an instant.
• When to cycle Broodwagon instead of holding it.
• Whether to fetch Greasefang or a reanimation creature with Speaker.

If you like graveyard decks that can also play a midrange game, this is a strong choice. If you want a linear deck that plays the same way every game, it is not. The fast kill only matters if you also know how to win the turn-seven game where your opponent answered the first Greasefang. That longer game is where Broodwagon, Chariot and the reanimation creatures do their work.

Core Strategy & Game Plan

How the Deck Wins

The deck wins by putting Parhelion II into your graveyard early, then letting Greasefang, Okiba Boss bring it back for free. At the beginning of combat on your turn, Greasefang, Okiba Boss returns a Vehicle card from your graveyard with haste. Greasefang's 4 power exactly meets crew 4. Crewing taps creatures but isn't a {T} ability, so a Greasefang cast that same main phase can crew. Parhelion II attacks as a 5/5 flier with first strike and vigilance and brings two attacking 4/4 flying Angels with it. That is 13 evasive damage from one three-mana creature and one card in the yard.

Parhelion returns to your hand at your end step, but the Angels stay. Even if the opponent answers the engine afterward, you keep two vigilant 4/4 fliers. One connection usually leaves the game a turn or two from over.

The Engine: Fill, Find, Fire

Every slot does one of three jobs.

• Fill the yard. Your discard outlets are Professor of Symbology (learn lets you discard to draw), Formidable Speaker, Bitter Triumph, Collective Brutality escalate, and cycling Thundering Broodwagon, which puts a Vehicle in the yard by itself. Your mill effects are Something Worth Saving and impending Overlord of the Balemurk. Both dig four cards deep, so they can bin Parhelion and hand you the missing piece in one action.
• Find Greasefang. Formidable Speaker discards Parhelion and tutors Greasefang with the same trigger, so it assembles the whole combo by itself. Overlord of the Balemurk and Takenuma, Abandoned Mire return Greasefang to your hand after removal. Yathan Roadwatcher and Emptiness cast with {W}{W}, either full price or evoked, put a Greasefang straight from the graveyard onto the battlefield.
• Protect the turn. Thoughtseize removes the instant-speed answer before you commit. Jennifer Walters stops your opponents from casting spells during your turn. That shuts off removal in response to the Greasefang trigger and blocks fog-style or flash-blocker answers in combat.

Posture: Proactive Combo With a Fair Backbone

You are the proactive deck in almost every matchup. Your interaction exists to clear a path, not to grind:

• Thoughtseize and Collective Brutality strip answers.
• Bitter Triumph kills a blocker or a fast threat while discarding Parhelion.
• Boseiju, Who Endures removes an artifact or enchantment, and its channel costs one less when Greasefang is out.

Removal does double duty here. Against an aggressive field, the cheap kill spells buy the one turn you need. UR Aggro was the most-represented archetype in recent Top 8s (source: MTGTop8, 2026-10-01 to 2026-10-15). Against slower decks, discard is the priority: you only need one window.

The Vehicles also give you a real fair game when the graveyard plan is shut down:

• Esika's Chariot cast for four makes two Cats, and those Cats crew Parhelion or Broodwagon.
• Greasefang can also return Esika's Chariot from the yard for two fresh Cats every turn.
• Thundering Broodwagon returned by Greasefang destroys a nonland permanent with mana value 4 or less on entry. Because it bounces to your hand at end step, you can cycle it again or hard-cast it later for another kill.

The Ideal Game, Turn by Turn

1. Turn 1: Thoughtseize, aimed at their removal or their fastest threat. If you have no one-drop, play a land that enters tapped, like Concealed Courtyard or Blooming Marsh while they're still untapped, and save shock life.
2. Turn 2: Professor of Symbology and discard Parhelion II to draw. Alternatives:
   • Impending Overlord of the Balemurk to mill four and pull back a creature.
   • Hold up Something Worth Saving and fire it on their end step.
   Lead with the instant if you also have Greasefang in hand. The permanent you take is then a free bonus rather than a requirement.
3. Turn 3: Greasefang, Okiba Boss. At beginning of combat, return Parhelion, crew with Greasefang, and attack for 13 in the air. If your turn-2 play was Formidable Speaker on a mana-heavy hand, this is your Speaker turn instead, and the attack comes on turn 4.
4. Turn 4 and beyond: Swing with the Angels. Re-bin Parhelion with any discard outlet so Greasefang can do it again, or add Jennifer Walters to lock out interaction on your turn. If they killed Greasefang, rebuy it:
   • Emptiness evoked with {W}{W} to put it back on the battlefield.
   • Yathan Roadwatcher to put it back on the battlefield.
   • Takenuma, Abandoned Mire or Overlord of the Balemurk to return it to your hand.

Choosing the Right Vehicle

When more than one Vehicle is in your graveyard, read the board before the trigger:

• Parhelion when you are racing or closing.
• Broodwagon when a single permanent with mana value 4 or less is the thing beating you, such as a blocker, a lock piece, or a graveyard-hate permanent.
• Chariot when you need bodies to crew the bigger Vehicles next turn or to stabilize against go-wide pressure.

Remember that a returned Vehicle bounces at your end step either way. Choose the one whose immediate effect matters most this turn, because you will be re-enabling the graveyard from scratch regardless.

Card Choices & Breakdown

The Engine: Greasefang and Its Vehicles

4 Greasefang, Okiba Boss is the deck. At the beginning of combat it returns a Vehicle from your graveyard with haste, and its 4 power crews anything in the list by itself. Four copies is non-negotiable. Every other slot either puts a Vehicle in the yard, finds or rebuys Greasefang, or protects the turn it goes off.

4 Parhelion II is the payoff. On attack it creates two 4/4 flying, vigilant Angels that enter attacking, alongside a 5/5 flying first-striker. At eight mana it is never meant to be cast. It is meant to be discarded, which is why you want four: drawing extras is fine because every discard outlet in the deck turns a dead Parhelion into a live one.

3 Thundering Broodwagon is the second reanimation target and the one that interacts. When Greasefang returns it, the enter trigger destroys an opposing nonland permanent with mana value 4 or less, and it comes back with reach and menace. Cycling {2} puts it in the graveyard on your own terms, so it is a self-loading Vehicle when you lack a discard outlet. It sits at three because it is a weaker top-end hit than Parhelion, but the cycling means a drawn copy is rarely dead.

4 Esika's Chariot is Plan B and part of Plan A. Cast fairly, it is a four-mana threat whose two Cats together crew 4, which means they can crew a Greasefang-returned Parhelion II if Greasefang itself is needed elsewhere. The Chariot's attack trigger copies a token, and that includes a 4/4 Angel. It is also a Vehicle, so Greasefang can loop it from the yard after removal.

Enablers: Discard, Tutor, Mill

• 4 Professor of Symbology: Learn gives you a choice. You can discard Parhelion to draw a card, or fetch a Lesson from your sideboard. That second option is why the sideboard carries Enter the Avatar State (hexproof for Greasefang), Origin of Metalbending (indestructible, or artifact/enchantment removal), Ruinous Waterbending and Germination Practicum. Every Lesson you register is a card the Professor can find.
• 4 Formidable Speaker: The single best enabler. You discard Parhelion and search for Greasefang in one trigger, which sets up the turn-three combo by itself. Its untap ability also works on a land, giving you extra mana on later turns.
• 3 Something Worth Saving: Instant-speed mill four that also keeps a permanent card from the milled cards. You can cast it at the end of the opponent's turn to bin a Vehicle and pick up a missing Greasefang or land. It is the third enabler rather than a fourth because, unlike the Professor and the Speaker, it doesn't guarantee a Vehicle in the yard.

Rebuy Package: Getting Greasefang Back

Greasefang is mana value 3, and that is the key to this package.

• 1 Yathan Roadwatcher mills four when cast and returns a creature card with mana value 3 or less to the battlefield. That target is usually Greasefang, often with a Vehicle from the same mill.
• 1 Emptiness returns Greasefang directly if {W}{W} was spent. You can evoke it for two mana or hard-cast it. At six mana you can spend both {W}{W} and {B}{B} and get both the reanimation and the -1/-1 counters.
• 1 Overlord of the Balemurk cast for impending {1}{B} still enters and triggers: mill four, return a non-Avatar creature to hand. On turn two it fills the yard and digs up Greasefang.

Each is a singleton because each does something slightly different and none is a free roll. The spread gives you redundancy against graveyard-light removal without diluting the enablers.

Interaction

• 4 Thoughtseize: Strips the removal spell that would break up Greasefang before you commit to the combo turn. Play it turn one when you can.
• 2 Bitter Triumph: Two-mana instant removal for a creature or planeswalker. Its discard cost is another outlet for Parhelion, so the "drawback" often advances your plan.
• 1 Collective Brutality: Escalate also discards, so the same logic applies. The instant/sorcery mode, the -2/-2 mode and the drain cover different opponents. UR Aggro was the most-represented archetype in recent Top 8s (source: MTGTop8, 2026-10-01 to 2026-10-15), which makes a card that hits both cheap creatures and spells a sensible singleton.
• 1 Jennifer Walters: Opponents can't cast spells during your turn. That shuts off the instant-speed answer to a Greasefang trigger or a crewed Parhelion on the turn it matters. As a legendary creature it also discounts both channel lands.

Mana Base (23 Lands)

Greasefang needs {W}{B} on turn three, and the green is there for Speaker, Chariot and Something Worth Saving.

• Two-color lands: Four Temple Garden, four Blooming Marsh, three Concealed Courtyard, two Godless Shrine and one Overgrown Tomb cover all three color pairs.
• Multiversal Passage: Four copies fill whatever color you are missing. Name a type based on your hand, not habit.
• Channel lands: Takenuma, Abandoned Mire is a late-game Greasefang rebuy. Boseiju, Who Endures is uncounterable-feeling artifact, enchantment or nonbasic land removal. Both get cheaper with Greasefang or Jennifer Walters in play.
• Basics: One Plains, one Swamp and one Forest. The Plains and Forest are what Yasharn, Implacable Earth fetches after sideboarding.

Yasharn also stops all players from paying life, which shuts off your own shocks, Thoughtseize and Bitter Triumph's life mode. Keep that in mind when you bring it in.

The Decklist

This is the 60 and 15 that finished Top 4 at the MTGO Challenge 32 on 2026-10-22 (40 players, played by jarold9). The main deck is 16 creatures, 11 Vehicles, 10 spells and 23 lands, at an estimated total of about $229 at TCGplayer market prices. The engine is 4 Greasefang, Okiba Boss and 4 Parhelion II plus the discard and mill cards that put Parhelion in the graveyard. Those slots are locked. The one-ofs and the off-four counts are where you have room to tune.

Main Deck

Sideboard

Four of the sideboard cards are Lessons, which turns every Professor of Symbology into a modal card after sideboarding. When you trim the board for an expected field, keep at least one protective Lesson and one removal Lesson so learn always has a live target. Several sweepers here clip your own cheap creatures. Bring them in when the opponent's board is worth more than your Professors, not by default.

Mulligan Guide

Greasefang hands come in two kinds: hands that can put Parhelion II onto the battlefield on turn 3 or 4, and hands that hope to. Keep the first kind and be strict about the second. A hand that casts a few fair spells and never assembles the engine loses to almost everything in this format.

What a Keep Needs

• White and black by turn 3. Greasefang, Okiba Boss costs {1}{W}{B}. Godless Shrine, Concealed Courtyard, and a Multiversal Passage set to Plains or Swamp all count toward this. A hand with green but no white is not a Greasefang hand.
• A way to bin a Vehicle. Your outlets are Professor of Symbology (learn lets you discard a card to draw a card), Formidable Speaker, Bitter Triumph, Something Worth Saving, an impended Overlord of the Balemurk, and an escalated Collective Brutality.
• Greasefang or a route to it. Formidable Speaker searches for it. Something Worth Saving and Overlord of the Balemurk can dig it up. Yathan Roadwatcher and Emptiness can return it from the graveyard.

You don't need Parhelion II in your opening hand. Milling it or drawing into it works too. The hands you can't keep are the ones missing a piece with no realistic way to find it.

Example Hands

1. Godless Shrine, Blooming Marsh, Temple Garden, Thoughtseize, Professor of Symbology, Greasefang, Okiba Boss, Parhelion II: Snap keep. Turn 1 Thoughtseize strips their best answer. Turn 2 Professor of Symbology discards Parhelion II. Turn 3 Greasefang, Okiba Boss crews it alone with its 4 power and attacks for 5 in the air alongside two attacking 4/4 Angels. This is the hand the deck is built to produce.

2. Overgrown Tomb, Concealed Courtyard, Plains, Formidable Speaker, Something Worth Saving, Bitter Triumph, Esika's Chariot: Keep. You have no Greasefang and no Parhelion, but you have two ways to assemble the combo:

• Something Worth Saving at the end of the opponent's turn 2 can mill a Vehicle and grab a permanent.
• Formidable Speaker on turn 3 can discard Esika's Chariot or a dead card to tutor Greasefang.

Bitter Triumph handles their early threat. Even if the engine stalls, Esika's Chariot on turn 4 is a real fair plan.

3. Swamp, Takenuma, Abandoned Mire, Forest, Thoughtseize, Parhelion II, Parhelion II, Thundering Broodwagon: Ship. There's no white source, no outlet, and no Greasefang. Two uncastable Parhelions plus a six-drop add up to one live card. Takenuma, Abandoned Mire won't fix a hand that has nothing to channel toward.

4. Temple Garden, Godless Shrine, Professor of Symbology, Greasefang, Okiba Boss, Parhelion II, Thoughtseize, Bitter Triumph: Keep on the play or the draw. It's a two-lander, but every spell costs three or less and the hand already contains the full combo. Professor of Symbology bins Parhelion and replaces itself, so you get an extra look at a land. If you whiff on land drops, Bitter Triumph can discard a second copy of something later.

5. Godless Shrine, Concealed Courtyard, Forest, Jennifer Walters, Thoughtseize, Greasefang, Okiba Boss, Parhelion II: Keep on the draw; ship on the play against aggro. You have both halves but no outlet, so you're drawing to one of the many enablers. Against slower decks, Thoughtseize and Jennifer Walters keep you safe while you dig. On the play against UR Aggro or Red Deck Wins, a hand that doesn't interact and may not combo until turn 5 is too slow.

On the Play vs. On the Draw

On the play, value speed. A hand that threatens Parhelion on turn 3 is worth keeping even if it's thin on backup, because the opponent often has only one untapped land to answer it.

On the draw, the extra card makes one-piece-short hands like Hand 5 reasonable. Lean toward hands with interaction, since you'll be facing a board before your engine is online. Also expect Thoughtseize to be weaker against aggro on the draw, because their hand has already emptied onto the table.

Matchup Adjustments

UR Aggro was the most common Top 8 archetype in the sample (15 of 48 Top 8 slots; source: MTGTop8, 2026-10-01 to 2026-10-15). Keep these hands against it:

• Hands that either combo by turn 3 or hold Bitter Triumph or Collective Brutality plus a Greasefang line.
• Hands where your outlets don't all cost life. With shocklands, Thoughtseize, and the Triumph life mode, it adds up quickly.

After sideboarding, value Jennifer Walters more. Those UR Aggro lists carried It'll Quench Ya! and Spell Pierce in 13 of 15 sideboards each (source: MTGTop8 deck exports, 2026-10-01 to 2026-10-15). Nothing they hold can be cast during your turn while she's on the battlefield.

Red Deck Wins: The same rules apply, but be even stricter about life. Ship slow hands that also need two shocklands to function.

Jund Sacrifice and The Rock: These are longer, interactive games, so resilience beats speed. Prefer hands with redundancy:

• Two outlets.
• A backup route to Greasefang, such as Overlord of the Balemurk, Yathan Roadwatcher, or Takenuma, Abandoned Mire.
• Thoughtseize to clear the path.

A hand with one Greasefang and no follow-up is a ship if it has nothing else to do.

Control decks (Izzet Control appears in the sample): Thoughtseize and Jennifer Walters go up in value. A slower hand that protects the combo is better than a fast hand that runs it into open mana.

Sequencing & Key Lines

Land Sequencing

Your fastlands want to be played early. Concealed Courtyard and Blooming Marsh enter untapped only while you control two or fewer other lands, so they belong on turns one and two. Save Temple Garden, Godless Shrine, Overgrown Tomb and Multiversal Passage for turn three and later, where you choose between paying 2 life and entering tapped. A tapped shockland is often correct on a turn when you only need two mana.

Plan your colors backward from turn three. Greasefang, Okiba Boss needs W and B. Formidable Speaker and Something Worth Saving need G. Thoundering Broodwagon needs BBGG to hardcast, but you rarely hardcast it.

Against aggro, watch your life total. Thoughtseize, shocklands and Bitter Triumph's life option all cost life. UR Aggro had the most Top 8 slots of any archetype in recent large events (source: MTGTop8, 2026-10-01 to 2026-10-15), so treat every 2 life as a real cost in that matchup.

The Standard Turn-Three Kill

1. Turn one: Thoughtseize if you have it. Taking their answer to Greasefang matters more than taking their best threat.
2. Turn two: Professor of Symbology. Learn by discarding Parhelion II to draw a card.
3. Turn three: cast Greasefang, Okiba Boss and move to combat. Greasefang returns Parhelion and gives it haste. Tap Greasefang's 4 power to crew it, since crewing only taps creatures. Parhelion attacks and makes two attacking 4/4 flying Angels.

At your end step, Parhelion returns to your hand, but the Angels stay. Next turn, discard Parhelion again with any outlet and repeat.

When Formidable Speaker and Professor are both on the battlefield, crew with them (2 + 2 power) instead of tapping Greasefang. Greasefang can't attack the turn it comes down anyway, and leaving it untapped gives you a 4/3 blocker against aggro.

Choosing Your Discard Outlet

• Professor of Symbology: the default when you hold both halves of the combo. If your hand is already set and you expect removal on Greasefang, learn for Enter the Avatar State from your sideboard instead. It gives a creature hexproof in response to targeted removal. Against go-wide aggro, Ruinous Waterbending is the Lesson to fetch.
• Formidable Speaker: the turn-three play when you have Parhelion but no Greasefang. Discard Parhelion and fetch Greasefang. Speaker can also fetch Jennifer Walters or a rebuy creature, depending on the game state.
• Bitter Triumph: instant speed, so it is your best outlet against graveyard hate (see below). On the draw against aggro, discarding Parhelion to kill their two-drop is the ideal two-for-one.
• Something Worth Saving: cast it at your opponent's end step on turn two. Any Vehicle it mills stays in the graveyard as a target, and you take Greasefang or a land from the four cards.
• Thundering Broodwagon: cycling for {2} puts it in your graveyard and replaces itself.

Choosing Which Vehicle to Return

Parhelion is the kill. The other two Vehicles are better in specific spots.

• Thundering Broodwagon: return it when you need to remove a nonland permanent with mana value 4 or less. Greasefang crews it, and it attacks as a 6/5 with menace. When it returns to your hand at end step, cycle it again for {2}. This repeatable loop grinds midrange decks out.
• Esika's Chariot: return it to make two Cats, which crew it on the same turn. Its attack trigger copies any token you control, so once you have Angels, have it copy an Angel rather than a Cat. When it bounces at end step, you can recast it for another pair of Cats.

When several Vehicles are in your graveyard, the general rule is: Broodwagon if a blocker or hate piece stops your attack, Parhelion if the opponent's board can't block flyers, and Chariot if you need to go wide against removal.

Playing Around Interaction

Graveyard hate: don't leave Parhelion in the graveyard across their turn when you don't need to. Cast Greasefang first. Then, in your first main phase, discard Parhelion with Bitter Triumph and go straight to combat. Their only window to exile it is in response, with instant-speed effects.

Instant-speed removal: Jennifer Walters stops your opponents from casting spells during your turn. With Jennifer on the battlefield before Greasefang's combat, they can't cast a spell to answer the trigger or the attack. When you have the mana, Jennifer on turn two followed by Greasefang on turn three is worth delaying your learn.

Removal in response to the trigger: if they kill Greasefang with the trigger on the stack, the trigger still resolves. The Vehicle still returns with haste, but you now need 4 power from other creatures to crew it. Keep that crew on the battlefield whenever you can.

Rebuying Greasefang

• Emptiness: evoke it with WW spent to return Greasefang directly to the battlefield, before combat on the same turn.
• Yathan Roadwatcher: does the same for four mana, but only if you cast it.
• Overlord of the Balemurk: impending for {1}{B} mills four and returns Greasefang to your hand.
• Takenuma, Abandoned Mire: channel it to mill three and return Greasefang to your hand. It costs {1} less for each legendary creature you control, so Jennifer on the battlefield discounts it.

Hold one rebuy piece rather than running every threat into open mana.

Matchup Matrix

UR Aggro

This is the deck to beat. It took 15 of 48 Top 8 slots and won 3 of 6 events (source: MTGTop8, 2026-10-01 to 2026-10-15). The label covers two builds, a Monastery Swiftspear version and a Vivi Ornitier version. Your answer is the same against both: kill them before their volume of cheap spells kills you.

The key moment is the Greasefang, Okiba Boss trigger. If they remove Greasefang in response, Parhelion II still comes back, but you have nothing to crew it. Jennifer Walters is your best tool here. Your opponents can't cast spells during your turn, so with her out, the beginning-of-combat trigger goes through clean.

Your plan:

• Pay Bitter Triumph's cost by discarding, not with life. The discarded card often fills your graveyard anyway.
• Use Formidable Speaker's 2/4 body as a blocker.
• Remember that the Angel tokens have vigilance, so they hold the ground on the swing back.
• Professor of Symbology can learn Ruinous Waterbending or Enter the Avatar State. The second gives Greasefang hexproof at instant speed.

Expect cheap countermagic after sideboarding. Spell Pierce and It'll Quench Ya! each appear in 13 of the 15 Top 8 sideboards (source: MTGTop8 deck exports, 2026-10-01 to 2026-10-15). For their side of the matchup, see our UR Aggro Pioneer guide.

Jund Sacrifice

They win long, grinding games on the ground. You win in the air. A single unanswered Parhelion II attack puts a 5/5 first striker and two 4/4 fliers into the red zone. Their plan is not built to block that.

Thundering Broodwagon does double duty here. Its ETB kills a key engine piece, and each time Greasefang, Okiba Boss returns it from the graveyard, the ETB fires again. After sideboarding, Yasharn, Implacable Earth shuts off sacrificing nonland permanents to cast spells or activate abilities, which hits the heart of their deck.

Don't overcommit discard early. Save Thoughtseize for the payoff, not the fodder. For their side, see our Jund Sacrifice Pioneer guide.

The Rock

This is the hardest of the fair matchups. They play discard and removal, and they can strip a Greasefang from your hand or kill it on board. You beat them on redundancy:

• Yathan Roadwatcher and Emptiness (cast with {W}{W}) both return Greasefang from the graveyard.
• Takenuma, Abandoned Mire and Overlord of the Balemurk return it to your hand.
• Esika's Chariot gives you a fair plan that doesn't touch the graveyard at all.

Origin of Metalbending, fetched with learn, makes a creature indestructible against destroy effects. Professor Dellian Fel gives you a grind engine of your own. Don't race them. Out-card them, then convert with one Parhelion turn. For their side, see our The Rock Pioneer guide.

Izzet Control

Counterspells answer spells, not triggers. Once Greasefang, Okiba Boss resolves, the reanimation itself is a triggered ability. That means the fight is over resolving the three-drop.

Your plan:

• Lead with Thoughtseize to clear the counter.
• Cast Something Worth Saving at the end of their turn to bait mana and set up your graveyard.
• Land Jennifer Walters early when you can. She shuts off their instant-speed interaction on your turn completely.
• Use Collective Brutality's instant-or-sorcery discard mode, which is at its best here.

Red Deck Wins

Your mana base fights you here. Shocklands, Multiversal Passage, Thoughtseize and Bitter Triumph all cost life, and burn turns every point into reach.

Your plan:

• Play lands tapped whenever the curve allows.
• Pay Bitter Triumph's cost by discarding.
• Prioritize blockers, especially Formidable Speaker and the Cats from Esika's Chariot.
• Be willing to skip Thoughtseize entirely.

Pest Control and Ruinous Waterbending help against go-wide starts. Your Angels' lifelink-free vigilance bodies are defense, not lifegain. Plan accordingly. For their side, see our Red Deck Wins Pioneer guide.

Other aggro

Treat the smaller aggressive decks like a slower UR Aggro. Keep removal for their best threat, block with Speaker, and get your first Parhelion attack in on turn three or four. A turn-three Greasefang crews Parhelion II by itself the same turn, because crewing doesn't require the creature to have been under your control since the start of the turn. That swing ends most races.

Combo and big mana

These decks ignore your board and race to their payoff. Thoughtseize takes the key piece and your clock does the rest. They rarely interact with a reanimated Vehicle on your turn, so keep any hand that puts Greasefang down on curve with a Vehicle already in the yard.

Other graveyard decks

Expect either a straight race or post-board graveyard hate. Mill aggressively and win fast. Unlicensed Hearse can disrupt their yard while it grows into a threat. Keep Esika's Chariot in so you have a plan B if they exile your graveyard.

Sideboard / Tech Guide

Your sideboard does two jobs. Some of the fifteen are real swaps between games. The four Lessons (Enter the Avatar State, Origin of Metalbending, Germination Practicum, Ruinous Waterbending) usually stay where they are, because they are the targets Professor of Symbology learns from outside the game. Sideboarding a Lesson in moves it into your deck and takes it out of that learn pool. So the default is to leave the Lessons alone and let Professor fetch the right one for the matchup. Swap in the non-Lesson cards.

UR Aggro

This is the deck you have to prepare for. It took 15 of 48 Top 8 slots across the six counted events (source: MTGTop8, 2026-10-01 to 2026-10-15). The label covers two builds, so identify which one you are facing in game one.

• Swiftspear build — In: 2 Abrupt Decay, Witherbloom Command, Vanishing Verse, Pest Control. Out: 3 Thoughtseize, Yathan Roadwatcher, 1 Something Worth Saving.
• Vivi build — In: 2 Abrupt Decay, Witherbloom Command, Vanishing Verse. Out: 2 Thoughtseize, Yathan Roadwatcher, 1 Something Worth Saving. Keep two Thoughtseize here, because this build relies more on spells and engine pieces you want to strip before they come online.

The life loss from Thoughtseize is a real cost against a burn-backed clock, and a four-mana value creature is too slow. Pest Control only belongs in the deck when their threats are clustered at one mana. It also destroys every one of your tokens, which have mana value 0. That includes your Cats from Esika's Chariot and Angels from Parhelion II, so cast it before you build a board.

Learn Ruinous Waterbending when they go wide. Learn Enter the Avatar State when you need lifelink and a blocker that won't die, or need a crewed Vehicle to dodge a removal spell. With Bitter Triumph, always choose the discard cost over 3 life in this matchup.

Red Deck Wins

In: 2 Abrupt Decay, Witherbloom Command, Vanishing Verse. Out: 4 Thoughtseize.

This is the same logic as against UR Aggro, pushed further. Your life total is the resource they attack, so cut every card that spends it. Keep Collective Brutality and Emptiness. The drain mode and an evoked Emptiness cast with {B}{B} are both cheap, early interaction. Witherbloom Command kills an X/1 and drains 2 in a single card.

Jund Sacrifice

In: Yasharn, Implacable Earth, Culling Ritual, Drana and Linvala. Out: 2 Bitter Triumph, Collective Brutality.

Spot removal trades poorly against a deck that wants its creatures to die. Yasharn, Implacable Earth stops any player from sacrificing nonland permanents to cast spells or activate abilities. It also shuts off the pay-life mode of Bitter Triumph, which is one more reason to cut that card here. Your shocklands and Multiversal Passage are unaffected, because paying life as a land enters is not a cost to cast a spell or activate an ability. Yasharn also fetches your basic Forest and Plains.

Drana and Linvala turns off their creatures' activated abilities and gives them to you. Culling Ritual wipes every nonland permanent with mana value 2 or less, including your own Professor of Symbology, Jennifer Walters and tokens. Cast it before you commit those. The {B} or {G} it adds back can pay for a follow-up the same turn.

The Rock

In: Professor Dellian Fel, Vanishing Verse. Out: Collective Brutality, 1 Bitter Triumph.

This is a grind. You want threats that don't depend on your graveyard, plus clean answers. Professor Dellian Fel draws cards, kills creatures and gains life, and it is a different card type for their answers to deal with. Keep Jennifer Walters in. Your opponents can't cast spells during your turn, so they can't kill Greasefang, Okiba Boss in response to its combat trigger or during your attack.

If they show graveyard hate, change your priorities:

• Use Something Worth Saving to put permanents into your hand, not as a way to stock the graveyard.
• Value Overlord of the Balemurk returning creatures to hand.
• Value Takenuma, Abandoned Mire.
• Be willing to hard-cast Esika's Chariot as your main plan.

Learn Origin of Metalbending to give Greasefang, Okiba Boss indestructible against destroy effects, or to answer a key artifact or enchantment.

Control (Izzet Control, Dimir variants)

In: Professor Dellian Fel, Drana and Linvala. Out: 2 Bitter Triumph.

Against decks with few creatures, cut the dead removal and add threats that pressure them from different angles. Keep Collective Brutality, since its discard mode takes instants and sorceries specifically. Keep every Thoughtseize. Jennifer Walters is one of your best cards here: on your turn they can't counter or remove anything you do. Learn Germination Practicum in long games. Its Paradigm keeps adding counters every turn without spending another card.

Dredge

In: 2 Unlicensed Hearse. Out: Jennifer Walters, Yathan Roadwatcher.

Unlicensed Hearse exiles up to two cards from a single graveyard every time you tap it, and it grows as it does. It is crew 2, so Professor of Symbology or Formidable Speaker can crew it in a pinch. Point it at their yard, never yours. Your own graveyard is where Parhelion II lives.

Adjusting for the field

If you expect an aggro-heavy room, add a third cheap removal spell over Professor Dellian Fel. The two most-represented strategies after UR Aggro, Jund Sacrifice and The Rock, each held 5 Top 8 slots (source: MTGTop8, 2026-10-01 to 2026-10-15). That spread makes the current split of the fifteen reasonable. Don't cut the Lessons to make room. They are what let a single Professor of Symbology become the right answer in every matchup.

Tech Choices & Variations

The engine is fixed: four Greasefang, Okiba Boss, four Parhelion II, four Esika's Chariot, four Professor of Symbology, four Formidable Speaker, and the Thoughtseize set. Roughly ten to twelve slots around that core can move without breaking the deck. Those are the singletons, the removal split, the vehicle and mill counts, and the utility lands.

The Single-Copy Reanimation Slots

Yathan Roadwatcher and Emptiness both return a creature with mana value 3 or less from your graveyard to the battlefield. That covers Greasefang, so each is a second route back into the combo after removal. Yathan Roadwatcher mills four first, which makes it the better topdeck when your graveyard is thin. It only works if you cast it, and its three-color cost is real. Emptiness costs two hybrid mana with evoke and has a second mode: paying {B}{B} puts three -1/-1 counters on a creature. That makes it the flexible copy against creature decks. You can't make a third copy of either from inside the 75. The trade-off is redundancy against interaction.

Overlord of the Balemurk is a self-mill engine that costs {1}{B} if you cast it for impending. It returns creatures to hand, not to the battlefield. Treat it as the slot you cut first when you want more interaction against fast decks.

Jennifer Walters is the protection slot. While she's out, your opponents can't cast spells during your turn, so Greasefang's beginning-of-combat trigger and your attack resolve without instant-speed answers. Formidable Speaker can tutor her, so one copy plays like more. Against decks with little instant-speed interaction, she's a 2/3 you can swap for Drana and Linvala or Yasharn, Implacable Earth.

The Interaction Split

Two Bitter Triumph and one Collective Brutality are tuned for a deck that wants to discard. Both let you pay part of their cost by discarding, so a stranded Parhelion II becomes removal and a graveyard setup at once. Main-deck alternatives from the sideboard:

• Abrupt Decay: can't be countered. It hits only mana value 3 or less and doesn't fill your graveyard. It's the right swap when your field leans on counterspells.
• Vanishing Verse: exiles at instant speed for two mana, but only monocolored permanents. Check your field's key threats before moving it in.
• Witherbloom Command: sorcery speed. It handles small creatures and cheap noncreature permanents in one card.

The cost of any swap is the same. You lose the discard outlet that turns dead Parhelions into value.

Vehicles and Mill Counts

Three Thundering Broodwagon is the right number. When Greasefang returns it, its enters trigger destroys a nonland permanent with mana value 4 or less, and cycling {2} means it's rarely dead in hand. A fourth copy would come out of Something Worth Saving. That leans you toward removal-on-a-stick over consistency. Going down to two Something Worth Saving weakens your instant-speed mill on the opponent's end step, so only make that cut if your field punishes durdling.

The Lesson Toolbox

Every Professor of Symbology can learn, so the Lessons in your 15 act as main-deck options:

• Enter the Avatar State: gives a creature hexproof and protects Greasefang through a combat step.
• Origin of Metalbending: either an artifact/enchantment answer or indestructibility.
• Ruinous Waterbending: a -2/-2 sweep. Your Greasefang and Speakers survive it, but your Professors and Cat tokens die.
• Germination Practicum: the long-game Lesson.

Swapping Lessons is the cheapest tuning you can do. It changes your Professor targets without touching the 60.

Utility Lands

Takenuma, Abandoned Mire and Boseiju, Who Endures cost you very little. Their channel costs drop by {1} for each legendary creature you control, and both Greasefang, Okiba Boss and Jennifer Walters are legendary.

• Boseiju, Who Endures: a land-slot answer to artifacts and enchantments.
• Takenuma, Abandoned Mire: buys back a creature after a mill whiffs.

If you trim one, trim a basic, not either of these.

Tuning for Your Field

UR Aggro took 15 of 48 Top 8 slots across six 32+ player events (source: MTGTop8, 2026-10-01 to 2026-10-15). In those UR Aggro lists, It'll Quench Ya! and Spell Pierce each showed up in 13 of 15 sideboards (source: MTGTop8 deck exports, 2026-10-01 to 2026-10-15). Against a field like that:

• Before sideboarding: keep Jennifer Walters and Collective Brutality in the main. Brutality's -2/-2 and drain modes both line up against small creatures.
• After sideboarding: expect counters in games two and three and lean on Abrupt Decay.
• Against the Swiftspear build: Pest Control sweeps everything at mana value 1 or less, and it cycles when it's dead.
• Against the Agatha's Soul Cauldron build: a Culling Ritual or extra artifact hate earns its slot.

If your room is heavier on Jund Sacrifice, consider Yasharn, Implacable Earth. It stops players from sacrificing nonland permanents to cast spells or activate abilities. It also stops you from paying 3 life for Bitter Triumph, so plan to discard instead. Against graveyard decks like Dredge, Unlicensed Hearse is the slot to bring in. It's also a vehicle your Greasefang can return.

Budget Options

At an estimated $229 on TCGplayer market prices, this list is already affordable by Pioneer standards. The engine is not where most of that money goes. It most likely sits in the mana base and in Thoughtseize. Spend on what makes the engine function on curve, and cut what only adds polish.

Where the money likely sits

• Shock lands: Temple Garden, Godless Shrine, Overgrown Tomb.
• Fast lands: Blooming Marsh, Concealed Courtyard.
• Utility legendary lands: Boseiju, Who Endures, Takenuma, Abandoned Mire.
• Thoughtseize: a four-of format staple.
• Multiversal Passage: also a four-of.

The core engine is a different story. Greasefang, Okiba Boss, Parhelion II, Professor of Symbology, Formidable Speaker and Something Worth Saving are probably not the expensive part of the deck. Esika's Chariot may be the exception, but it is not optional (see below).

What you cannot cut

These cards stay at full count no matter the budget:

• 4 Greasefang, Okiba Boss, 4 Parhelion II: they are the deck.
• The enablers: 4 Professor of Symbology, 4 Formidable Speaker and 3 Something Worth Saving put Parhelion in the graveyard or find Greasefang.
• 4 Esika's Chariot: it creates two 2/2 Cats on entry, which gives you the 4 power to crew a Parhelion on a turn when Greasefang isn't attacking. It is also your best fair threat when the combo gets disrupted.

Don't build a version that trims these to save money. It will lose to its own inconsistency long before the mana base matters.

Acceptable swaps and what you give up

The Thoughtseize swap costs the least right now. UR Aggro was the most common archetype in the brief's Top 8 sample (source: MTGTop8, 2026-10-01 to 2026-10-15). Against that deck, Thoughtseize's 2 life loss hurts, and interaction that kills creatures does more work than hand disruption. You give up the most against slower, interactive decks. There, seeing their hand before you jam Greasefang is the whole point.

The mana base is the real compromise

This is a three-color deck with demanding pips:

• Greasefang, Okiba Boss needs {W}{B} on turn 3.
• Formidable Speaker and Something Worth Saving need {G}.
• Thundering Broodwagon wants {B}{B}{G}{G} if you hard-cast it rather than cycle it.

If you cut shock lands for tapped duals, sequence the tapped lands on turns 1 and 2. A turn-1 Thoughtseize or turn-2 Professor of Symbology are the plays you can afford to skip. Your third land must enter untapped and produce the color Greasefang still needs.

Keep Plains, Swamp and Forest in the deck. Basics give you clean mana if you add enters-tapped lands, and the shock lands carry basic land types too.

Don't push the basic count much higher than the swaps above. Each extra mono-colored land makes a Speaker-or-Greasefang turn 3 harder to assemble.

Keep the Lesson package

Professor of Symbology lets you reveal a Lesson from outside the game. That makes these sideboard cards part of your main-deck toolbox:

• Enter the Avatar State
• Origin of Metalbending
• Germination Practicum
• Ruinous Waterbending

Cutting them to save money also cuts Professor's flexibility. Without them, the learn trigger can only be used to discard a card and draw a card, which is still how you bin Parhelion II. Acquire them early.

Upgrade path

1. Engine at full count: 4 Greasefang, Okiba Boss, 4 Parhelion II, 4 Esika's Chariot, 4 Formidable Speaker, 4 Professor of Symbology, 3 Something Worth Saving, plus the Lessons.
2. Untapped dual lands: add Godless Shrine and Concealed Courtyard first, because {W}{B} is the Greasefang pairing. Then add Blooming Marsh, Temple Garden and Overgrown Tomb.
3. Multiversal Passage: it smooths whichever color your opening hand lacks.
4. Thoughtseize: buy it before the utility lands. It changes how you play the combo turn far more than a channel land does.
5. Boseiju, Who Endures and Takenuma, Abandoned Mire: these are free value on top of a working mana base.
6. Sideboard premiums last: Abrupt Decay, Vanishing Verse and Culling Ritual come in only for specific matchups. Fill those slots with spare Bitter Triumph copies until you finish the rest.

Common Mistakes

1. Sending Formidable Speaker after a Vehicle

Formidable Speaker searches for a creature card. Parhelion II, Esika's Chariot and Thundering Broodwagon are artifacts, not creature cards, so Speaker can't find any of them. The correct use is the reverse: discard the Vehicle to the Speaker trigger and fetch Greasefang, Okiba Boss. If you already hold Greasefang, fetch whatever creature fills the gap, usually Jennifer Walters for protection or Professor of Symbology for another discard outlet. If you have no Vehicle to pitch, decide whether the tutor is worth a real card or whether you skip the discard.

2. Taking Parhelion off Something Worth Saving

When Something Worth Saving mills Parhelion II, it's already where you want it. Taking it back to your hand undoes your own setup. Put Greasefang, a land, or the piece you're missing into your hand and leave the Vehicle in the yard. It's an instant, so cast it on your opponent's end step when you can. That keeps mana up on their turn and gives you the information before you commit your next turn. The exception is the turn you plan to fire Greasefang with nothing in the yard yet. Then cast it precombat, so a hit is in place before the beginning-of-combat trigger.

3. Paying life on autopilot

Many cards here can tax your life total: shocklands, Multiversal Passage, Thoughtseize, and the 3-life mode of Bitter Triumph. Against aggro, that adds up fast. UR Aggro took 15 of 48 Top 8 slots in the brief's sample (source: MTGTop8, 2026-10-01 to 2026-10-15), so you will face it.

• Play tapped lands on turns you weren't spending the mana anyway.
• Pay the 2 life only when the untapped mana changes what you cast this turn.
• With Bitter Triumph, discard a Vehicle instead of paying life. You remove a threat and stock the graveyard in one card.

4. Forgetting the Vehicle comes back to your hand

Greasefang, Okiba Boss returns the Vehicle to its owner's hand at the beginning of your next end step. After a big Parhelion II swing, the Parhelion sits in your hand again and needs another discard to be reused. Players who spend every outlet on turn three find themselves holding an eight-drop on turn five. Track your outlets: Professor's learn, Speaker's trigger, Bitter Triumph, and cycling Thundering Broodwagon for {2}, which also puts a Vehicle straight into the yard. Save one for the next loop.

Also choose the right Vehicle to return:

• Esika's Chariot leaves two Cat tokens behind every time it enters. That's the better pick against removal-heavy opponents.
• Thundering Broodwagon destroys a nonland permanent with mana value 4 or less when it enters.
• Parhelion II is the pick when the damage ends the game.

5. Botching the colors on your reanimators

Emptiness returns Greasefang only if {W}{W} was spent to cast it, whether you hard cast it or evoke it. Paying with black-producing lands gives you the -1/-1 counters instead, which may not be what you needed. Yathan Roadwatcher only triggers if you cast it. Plan your land drops around the white sources: Plains, Temple Garden, Godless Shrine, Concealed Courtyard, and Multiversal Passage named for Plains. When Emptiness or Roadwatcher is your route to Greasefang, don't spend those lands on something else first.

6. Firing Greasefang into an open board with no protection

The Greasefang trigger happens at beginning of combat. That gives the opponent a window to respond if they have instant-speed interaction. Jennifer Walters stops your opponents from casting spells during your turn, so cast her first in your main phase when you can. With Jennifer down, the trigger and the crew-and-attack happen through a locked window. Against opponents holding instant removal, the Lessons available through learn also protect you:

• Enter the Avatar State gives Greasefang hexproof until end of turn.
• Origin of Metalbending gives it indestructible until end of turn.

If you have neither Jennifer nor a protection Lesson against a deck showing open mana, ask whether waiting a turn costs less than losing your only Greasefang.

7. Learning on reflex

Professor of Symbology offers two modes: fetch a Lesson or rummage. Neither is the default.

• With a Vehicle in hand and none in the yard, discard it to draw. That is the combo.
• Once the Vehicle is in the yard, a Lesson that protects or answers is usually worth more than a random draw.

Pick the mode based on what the next combat step needs.

8. Sweeping your own board

Your sweepers hit your own creatures too, so count the damage to your board before you cast them.

• Ruinous Waterbending gives every creature -2/-2. It kills your own Professor of Symbology and Cat tokens. Jennifer, Speaker, and Greasefang survive it.
• Culling Ritual destroys each nonland permanent with mana value 2 or less. That includes Professor, Jennifer, and every token you control.
• Pest Control destroys all nonland permanents with mana value 1 or less. That includes your Cats and Angels.

Cast these before you build a board, or when what they kill on the other side clearly outweighs your own losses.

Tournament Prep & Final Notes

What to Practice Before the Event

Most of your games are decided before combat, by whether a Vehicle is in your graveyard when Greasefang, Okiba Boss sees its trigger. Goldfish until you can quickly name every route that puts a Vehicle in the yard from a given seven:

• Discard outlets: Formidable Speaker (discard a Vehicle, search up Greasefang, Okiba Boss), Professor of Symbology's learn rummage, Bitter Triumph's additional cost, and Collective Brutality's escalate.
• Mill: Something Worth Saving, Overlord of the Balemurk, the channel on Takenuma, Abandoned Mire, and a cast Yathan Roadwatcher.
• Self-binning: cycling Thundering Broodwagon for {2}.

Next, drill your Vehicle choice. Parhelion II is the haymaker. Thundering Broodwagon is removal that repeats every turn Greasefang survives. Esika's Chariot builds a board that lasts. When you mill several Vehicles at once, keep the one that wins this specific turn in the yard, and take whichever card best rebuilds your next turn into your hand.

Finally, rehearse post-board learn. Professor of Symbology can reveal a Lesson you own from outside the game. Before round one, know which of Enter the Avatar State, Origin of Metalbending, Germination Practicum and Ruinous Waterbending you want in each matchup, so you aren't deciding with the clock running.

Rules Interactions to Know Cold

• Greasefang targets at beginning of combat. The Vehicle must already be in your graveyard when the trigger goes on the stack. Every enabler has to resolve in your first main phase or earlier. Something Worth Saving is an instant, so casting it in your opponent's end step keeps your mana open and still sets up your turn.
• The Vehicle goes back to your hand at the beginning of your next end step. That is the end step of the same turn. Tokens stay, though. Parhelion's Angels and Chariot's Cats remain on the battlefield, and the Vehicle has to be re-binned to loop.
• Parhelion's Angels come from its attack trigger. They enter tapped-in, attacking. You must crew (Crew 4, which Greasefang covers alone) and actually attack to get them.
• Untap Greasefang after crewing. A Formidable Speaker you have controlled since the start of the turn can pay {1} and tap to untap Greasefang after it crews. Greasefang then attacks alongside the Vehicle.
• Broodwagon's removal works off reanimation. Its trigger is "when this Vehicle enters," so Greasefang returning it destroys a nonland permanent with mana value 4 or less. It comes back to hand at end step, so you can cycle it and do it again.
• Chariot copies any token you control. Once Angels are on the board, an attacking Esika's Chariot can copy an Angel instead of a Cat.
• Know the conditions on each reanimation card. Yathan Roadwatcher only triggers if you cast it. Emptiness returns Greasefang (mana value 3) only if {W}{W} was spent. Evoking it with two white satisfies that.
• Jennifer Walters stops spells, not abilities. Opponents can't cast spells during your turn. Activated abilities still work, and so does anything they cast on their own turn.
• Legendary creatures discount your channel lands. Takenuma, Abandoned Mire and Boseiju, Who Endures cost {1} less for each legendary creature you control. Greasefang plus Jennifer Walters makes Takenuma a {1}{B} activation.
• Yasharn affects your own costs. Yasharn, Implacable Earth stops players from paying life to cast spells. Once it's down, Bitter Triumph needs a discard. Shockland life payments aren't spell or ability costs, so they are unaffected.

Time Management

The deck isn't slow on paper, but it has a lot of small decisions. Mill-four choices, learn choices, Speaker tutors, and a stack of combat triggers add up across three games.

• Decide your Vehicle and tutor target during your opponent's turn.
• Don't re-evaluate every mill from scratch. Default to "keep the Vehicle that wins now."
• On MTGO, set a stop in your opponent's end step so you don't skip past your instant-speed Something Worth Saving window.
• When Greasefang's trigger asks for a target, have the choice already made.

Preparing for the Field

The brief's sample is small and indicative only. In it, UR Aggro took 15 of 48 Top 8 slots across six events, with Jund Sacrifice and The Rock at 5 each (source: MTGTop8, 2026-10-01 to 2026-10-15). Plan your reps around that:

• UR Aggro (most reps). It splits into two builds. One runs Monastery Swiftspear, the other Vivi Ornitier and Agatha's Soul Cauldron (source: MTGTop8 deck exports, 2026-10-01 to 2026-10-15). Learn to tell them apart by turn two. The Vivi build plays Seasoned Cryomancer and Fear of Missing Out, the Swiftspear build plays Swiftspear and Emberheart Challenger, and your removal priorities differ between them.
• Jund Sacrifice and The Rock. These are grindier midrange games. Practice the turns where Broodwagon loops and Chariot tokens carry the game instead of one big Parhelion swing.

No Pioneer bans landed in the 2026-10-12 announcement, and the next one is scheduled for 2026-11-30 (source: Wizards of the Coast, announced 2026-10-12). Your list is safe to register through that window.

Final Assessment

This build reached a Top 4 at a 40-player MTGO Challenge 32 on 2026-10-22, which is the only result on record for it. It has earned its place on the strength of its construction:

• Redundant enablers. There are many ways to bin a Vehicle and two ways to get Greasefang back from the yard.
• A fair backup plan. Broodwagon removal and Chariot tokens keep the deck functional when the combo is answered.
• Disruption. Thoughtseize and Jennifer Walters protect the key turn.
• A flexible sideboard. The Lesson package turns Professor into a toolbox after board.

At roughly $229, it's an accessible entry into a proactive Pioneer strategy. The deck rewards tight main-phase sequencing more than raw card quality. Put in the goldfish reps, know the triggers precisely, and it will hold up across a long day.

Frequently Asked Questions

How does the Greasefang Parhelion deck win games?

It puts Parhelion II into the graveyard early, then Greasefang, Okiba Boss returns it at beginning of combat with haste and crews it alone with its 4 power. Parhelion attacks as a 5/5 flying first striker and creates two attacking 4/4 flying Angels, which is thirteen power in the air as early as turn three.

What are the key enablers for getting Parhelion into the graveyard?

The discard outlets are Professor of Symbology, Formidable Speaker, Bitter Triumph, escalated Collective Brutality and cycling Thundering Broodwagon. Something Worth Saving and impending Overlord of the Balemurk mill four. The guide calls Formidable Speaker the single best enabler because it discards Parhelion and tutors Greasefang in one trigger.

How do I get Greasefang back after it gets removed?

Yathan Roadwatcher and Emptiness cast with {W}{W} put Greasefang straight from the graveyard onto the battlefield. Overlord of the Balemurk and Takenuma, Abandoned Mire return it to your hand instead. The guide advises holding one rebuy piece rather than running every threat into open mana.

What is the hardest matchup for Greasefang Parhelion in Pioneer?

Red Deck Wins is the one matchup rated unfavored, because shocklands, Multiversal Passage, Thoughtseize and Bitter Triumph all cost life. The Rock is called the hardest of the fair matchups, since its discard and removal can strip or kill Greasefang, so you win on redundancy instead of racing.

How should I play against UR Aggro with Greasefang?

The guide rates it even and says it is decided by whether Greasefang survives to its first combat. Jennifer Walters stops opponents from casting spells on your turn so the trigger goes through clean. Pay Bitter Triumph by discarding rather than with life, and use Formidable Speaker as a blocker.

What are the budget swaps for this Greasefang deck?

You can cut Thoughtseize for extra Collective Brutality, Bitter Triumph and Vanishing Verse. You can also replace Boseiju, Who Endures and Takenuma, Abandoned Mire with basics, or swap fast lands and some shock lands for enters-tapped duals at a tempo cost. Never trim Greasefang, Parhelion, Esika's Chariot or the core enablers.

Which Vehicle should Greasefang return when I have several in the graveyard?

Return Parhelion II when racing or closing the game. Return Thundering Broodwagon when a single permanent with mana value 4 or less is beating you, since its enters trigger destroys it. Return Esika's Chariot when you need Cat bodies to crew bigger Vehicles or to go wide against removal.

What should I practice before taking Greasefang Parhelion to a tournament?

Goldfish until you can quickly name every route that puts a Vehicle in the yard from a given seven, then drill choosing which Vehicle to return. Also rehearse which Lesson Professor of Symbology should learn in each matchup, so you aren't deciding with the clock running.
