Swarmyard Massacre

This is asymmetric board wipe design filtered through tribal accounting. The board wipe that scales with your own tribe is an old idea, but most of the genre either counts a static keyword or hits everything and asks you to rebuild afterward. Here the -1/-1 stacks per creature you control across four small-creature types (Insects, Rats, Spiders, Squirrels), and your own members of those types are exempt from the math entirely, so a wide swarm board translates directly into how far down the opponent's toughness sinks. The two Squirrel tokens up front are not a throwaway rider: they are the floor, guaranteeing the count never starts at zero and nudging the sweep from conditional to reliable even on a stalled turn. What keeps it honest is that the payoff is entirely front-loaded on your development. Cast it into an empty board and it only manages -2/-2; cast it with a developed vermin swarm and it becomes a one-sided wrath that leaves your side untouched. The four-type net is deliberately generous, because a single-tribe wipe would strand it in one narrow shell, while spanning four adjacent small-creature archetypes lets it sit in any of them. It is a sorcery-speed reset that rewards the exact thing a go-wide deck wants to be doing anyway: flooding the board with cheap bodies, then converting that width into removal.
