Blight-Breath Catoblepas kills a creature the moment it enters — no attack, no tap, just a triggered deathtouch breath that fires on ETL and on untap. The catch is the seven-mana body underneath, which means you're paying a steep rate for a removal spell stapled to a 3/3.

Commander is where Blight-Breath Catoblepas actually earns a slot, specifically in flicker and bounce shells that can retrigger the ETB repeatedly — Brago, King Eternal or Emiel the Blessed loops turn it into a repeatable removal engine. Outside of that exploit, it's too slow and too narrow for Legacy, Vintage, or Modern, where seven mana buys you something that closes the game rather than picks off one blocker. Pauper is the one exception worth noting: the trigger is powerful at common rarity and the format's creatures are fragile enough that the effect punches above the card's rate, though the mana cost still makes it fringe rather than staple.

Price Context
Current price
$0.09 bulk tier
At $0.09, Blight-Breath Catoblepas is deep bulk — you'll find it in any common box or throw-in trade. Bulk seven-drops rarely appreciate unless a new combo enabler drags them into demand, so buy it for the deck you need it in now and don't expect the price to move.
