Plague Spitter

Pestilence on legs, with a built-in clock pointed back at you. Where Pestilence asked for black mana and a steady supply of it to grind a board down, this folds the same idea into a recurring upkeep ping that ticks whether you like it or not, then fires one more pulse on the way to the graveyard. That second trigger is the part that makes it a removal card rather than an attrition engine: kill it, sacrifice it, chump it into a bigger creature, and you still squeeze out a damage to every creature and every player. What you get is a creature that doubles as a board sweeper aimed at one-toughness creatures and a slow drain on every life total at the table, your own included, which is the cost it pays for symmetry. It reads as a beating against go-wide token strategies and a steady source of reach in attrition mirrors, and the death pulse means trading into it is rarely the clean answer it looks like. The Phyrexian framing fits the function exactly: a thing whose presence is corrosive to everything around it, and whose destruction is just one more dose of the same poison.
