Omnibian turns any creature into a vanilla 3/3 Frog at instant speed — a repeatable, blue-green answer to commanders, utility creatures, and anything else that wins through its text box. At three mana to cast and two to activate, the rate is honest, and the effect is permanent until the creature leaves the battlefield.
Best Commanders
Commanders with the highest synergy
Grolnok, the Omnivore
Grolnok, the Omnivore mills creatures into exile and lets Frogs cast them for free, so Omnibian pulling double duty as a Frog that also neutralizes opposing threats fits the engine perfectly — every activation advances both the offense and the defense.
Clement, the Worrywort
Clement, the Worrywort cares about creatures entering and wants bodies that generate value without demanding resources, and Omnibian's repeatable activation gives the deck a way to strip threatening creatures of their abilities while keeping the board presence Clement rewards.
Format Analysis
Where it lives, where it can’t
| Format | Verdict |
|---|---|
| commander | legal |
| legacy | legal |
| modern | legal |
| pioneer | not legal |
| standard | not legal |
| vintage | legal |
| pauper | not legal |
| oathbreaker | legal |
Commander is where Omnibian earns its keep — the format is full of commanders and utility creatures that win entirely through their text boxes, and a repeatable instant-speed ability that blanks them is categorically strong in a multiplayer game. Legacy and Vintage are legal but uninterested; three mana for a situational creature-blanker doesn't compete with those formats' threat density and interaction speed. Omnibian's absence from Pioneer, Standard, and Pauper is a non-issue — it was never built for those shells.

Budget Alternatives
Cheaper options that do most of the same work
Lignify and Sudden Spoiling both hit the same axis — stripping abilities and reducing a creature to vanilla stats — for under $1 combined, though neither is repeatable. Omnibian's edge is that one card does the job indefinitely and can answer new threats as they land, which no single-use enchantment or instant can replicate.
Price Context
Current price
$6.75 mid tier
At $6.75, Omnibian sits in the mid tier — more than a bulk pickup but well short of a budget concern for a focused Frog or Simic build. The price is stable given its narrow but loyal home in Grolnok lists, so it's a fair buy if the effect fits your deck.
