Combustible Gearhulk card art
Combustible Gearhulk lands as a 6/6 first striker and immediately forces your opponent to give you three cards or eat damage equal to their combined mana values — either outcome is useful. The catch is that the opponent controls which mode they hand you, so against a savvy player with a healthy life total, you'll get the draw denied at exactly the wrong moment.

Best Commanders

Commanders with the highest synergy

01
Dr. Eggman

Dr. Eggman

80.4% of decks · synergy 0.77

Dr. Eggman's artifact-matters engine wants high-impact artifacts that generate value the turn they arrive, and Combustible Gearhulk delivers a threatening body plus a forced choice before removal can answer it.

02
Alena, Kessig TrapperGilanra, Caller of Wirewood

Alena, Kessig Trapper // Gilanra, Caller of Wirewood

77.0% of decks · synergy 0.74

Alena, Kessig Trapper // Gilanra, Caller of Wirewood cares about power and mana generation, and Combustible Gearhulk's 6 power feeds Alena's tap ability the same turn it enters, immediately converting the Gearhulk into additional mana.

03
Feldon of the Third Path

Feldon of the Third Path

79.6% of decks · synergy 0.69

Feldon of the Third Path reanimates artifact creatures from the graveyard as tokens, so once Combustible Gearhulk hits the bin it becomes a repeatable forced-choice engine — Feldon triggers the ETB every turn at a steep discount.

04
Tannuk, Steadfast Second

Tannuk, Steadfast Second

76.8% of decks · synergy 0.67

Tannuk, Steadfast Second rewards running large artifact creatures, and Combustible Gearhulk's high mana value means the damage mode swings hard when an opponent declines to let the cards through.

05

Megatron, Tyrant

65.2% of decks · synergy 0.62

Megatron, Tyrant's Decepticon-matters theme leans on powerful artifact creatures, and Combustible Gearhulk slots in as a top-end threat that generates value independent of whether Megatron is on the battlefield.

Format Analysis

Where it lives, where it can’t

FormatVerdict
commander
legacy
modern
pioneer
standard
vintage
pauper
oathbreaker

Combustible Gearhulk is legal in Commander, Legacy, Modern, Pioneer, Vintage, and Oathbreaker, but its competitive footprint outside Commander is essentially zero — six mana is a death sentence in Legacy and Vintage, and Modern and Pioneer have cleaner six-drop payoffs. Commander is where it lives, and even there it occupies a specific lane: decks that either loop ETBs (Feldon of the Third Path, reanimator shells) or need a high-mana-value artifact body for synergy math. In a straight goodstuff red deck it's merely fine, because the opponent will always take the worse-for-you mode when it matters most.

Price Context

Current price

$0.34 bulk tier

At $0.34, Combustible Gearhulk is firmly bulk, and that price reflects its narrow competitive window accurately. It's a safe pickup for synergy-specific builds without any meaningful financial downside, but don't expect the price to move — supply is deep and the card doesn't see enough cross-format demand to push it out of the bulk bin.
