Single Combat

A board wipe that leaves one thing standing per player, then bolts the door behind it. The genius of the design is in the second clause: most symmetrical wraths reset the board only to let both players immediately begin rebuilding, which favors whoever floods back first. Here the lockout window (through the end of your next turn) freezes both players out of creature and planeswalker spells, but that freeze rewards whoever kept the better survivor. The player with a lone haymaker chooses it and sacrifices nothing; the swarm deck chooses its best body and watches the rest die. Since neither side can rebuild until the window closes, the caster wants to already hold the superior single threat when the smoke clears, turning a symmetrical effect into a race decided before it resolves. The choose-then-sacrifice framing also threads past indestructibility and regeneration entirely, since a sacrifice sidesteps the protective keywords a fatty leans on. What it cannot do is answer a wide board on the cheap in the way it punishes one: a token deck still keeps its best creature, and the caster spent five mana at sorcery speed to trade one-for-many rather than one-for-all. That tension (a wrath that guts a swarm down to a single survivor while a solo threat pays nothing) is the price the design accepts for locking the rebuild step shut on both sides at once.
