Triumph of the Hordes

Overrun rewritten in the language of poison. The Overrun template (an anthem with trample stapled to it) has always been the green wide-board finisher, converting a developed battlefield into lethal in a single attack step. Swapping out raw damage for infect changes the math underneath that finish: now the threshold is ten poison counters, not the opponent's life total, and the +1/+1 each creature gets is counting toward that smaller, fixed number. A trio of modest creatures that could never push twenty through chump blocks suddenly only needs to land for ten, and trample helps the counters get past whatever sits in the way. The genius and the danger both live in how front-loaded the kill becomes: a board that looks unthreatening on life totals is one cast away from a lethal poison swing the opponent never saw building. Against creatures the infect keyword does its second job, distributing -1/-1 counters that shrink or kill blockers permanently rather than dealing damage that resets at end of turn. The card asks for nothing it cannot reasonably expect from a green deck (bodies on the battlefield) and rewards that with a kill condition that bypasses lifegain and the comfortable assumption that thirty-plus life is a safe cushion.
