Feeding Frenzy

Removal whose magnitude is set by a creature count rather than a fixed number, and the count is the whole story: it tallies every Zombie on the battlefield, both yours and the opponent's, so the spell's bite swells with the entire undead population in play rather than your half of it. In a board with no Zombies it does literally nothing; with a few it shaves a midsize body; once the type has flooded the table it answers nearly anything single-target, killing across toughness tiers, clearing a blocker mid-combat, or removing a problem creature at instant speed. That conditionality is the cost for the flexibility: the text is inert as a topdeck or in a deck without the bodies to feed it, so it works less as standalone interaction than as a payoff layered onto an undead theme already humming. It sits in a long line of tribal removal that counts a creature type instead of pricing a fixed effect, trading reliability for a ceiling that scales with how committed the table is to the tribe. The wrinkle is that an opposing Zombie deck pumps your X just as readily, which can turn a mirror into a removal arms race where both sides hold this back for the moment the count peaks. Its identity rests on that swing from dead card to lethal answer, dictated entirely by how many undead are standing when it resolves.
