Virulent Plague

A surgical answer to a problem that grew up alongside it. As token-generators got cheaper and wider, sweepers built for board presence kept missing the point: a Wrath answers the creatures on the battlefield, but it does nothing about the engine still stamping out new ones. This sidesteps the question of how many tokens are out by attacking what most of them share, a small printed size, with a permanent static debuff. A 1/1 dies the moment it resolves; a 2/2 follows; anything minted afterward at that size arrives already dead, though a larger token (a 3/3 Beast, a 4/4 Angel) shrinks but survives. The asymmetry is the whole pitch: real creatures with stats off a card walk through it untouched, while every Saproling, Goblin, Zombie, Spirit, and Soldier the opponent will ever make is rendered inert without you having to respond to any individual one. That makes it a stance rather than a reaction, a passive tax that turns a whole go-wide plan into wasted mana for as long as it sticks. Black has plenty of removal that trades one-for-one; this is the rarer kind that trades one card for an opponent's whole strategy, provided that strategy is built on bodies the card can actually reach. The -2/-2 number is the load-bearing choice: low enough to be a clean three-mana enchantment, high enough to bury the small-token decks it was drawn up to hose, and deliberately short of touching the bigger tokens it was never meant to catch.
