Hydra Omnivore card art
Hydra Omnivore hits every opponent at once — in a four-player game, one unblocked swing is effectively 24 power spread across the table. The cost is a 8/8 body for six mana with no built-in evasion, but pair it with Triumph of the Hordes or run it under Gargos, Vicious Watcher to cheat the cost, and it closes games fast.

Gargos, Vicious Watcher

Gargos, Vicious Watcher

76.9% of decks · synergy 0.72

Gargos, Vicious Watcher reduces Hydra Omnivore's cost by four mana, making an 8/8 that damages all opponents a two-mana play — that's the entire engine in one sentence.

02
Zimone, Mystery Unraveler

Zimone, Mystery Unraveler

42.4% of decks · synergy 0.40

Zimone, Mystery Unraveler rewards drawing extra cards and running large threats, and Hydra Omnivore's ability to close out a multiplayer game in one attack cycle is exactly the payoff that shell wants at the top of the curve.

03
Xenagos, God of Revels

Xenagos, God of Revels

36.2% of decks · synergy 0.35

Xenagos, God of Revels doubles Hydra Omnivore's power at the start of combat, turning one attack into 16 damage dealt to each opponent simultaneously — a near-guaranteed three-player kill on the spot.

04

Polukranos Reborn

29.6% of decks · synergy 0.29

Polukranos Reborn is a Hydra tribal commander, and Hydra Omnivore slots in as one of the premier top-end threats in that lineup, offering board-wide pressure that other Hydras rarely match.

05
Felix Five-Boots

Felix Five-Boots

28.1% of decks · synergy 0.27

Felix Five-Boots grants a fifth-trigger doubling effect to creatures that deal damage, which means Hydra Omnivore's multi-opponent damage triggers stack — every opponent takes damage twice, turning the Hydra into a near-instant kill condition.

Hydra Omnivore is a Commander card through and through — its ability to deal damage to every opponent simultaneously is almost meaningless in one-on-one formats, where it's just an 8/8 for six with no additional text. In Legacy and Vintage it's technically legal but never played; six mana for a vanilla-in-practice creature doesn't compete with those format's broken threats. Commander is where Hydra Omnivore earns every slot: three or more opponents means one successful attack can swing the game state dramatically, and the math only gets better with damage doublers or infect enablers. Oathbreaker offers a similar multiplayer environment where it can pull its weight, though the faster pace shrinks the window to deploy it.

Price Context

Current price

$1.84 cheap tier

At $1.84, Hydra Omnivore sits at the low end of the mythic rare price curve — it's a genuine bargain for a card that appears in over 30,000 Commander decks. That price is stable; widespread play keeps supply moving but broad demand keeps it from bottoming out further.
