Mirror Strike

The trick is the redirection itself: an attacker swings, and the damage it would land on you turns around and strikes the player who sent it. Most early white combat answers either pumped a blocker or fogged the damage away; this one points the aggressor's own creature back at them, a hard punish for overextending into the red zone. The targeting clause is what narrows it: only an unblocked creature qualifies, so you cannot treat it as a free Fog against a full attack. You pick one threat the damage is coming from and bounce that one home, which rewards the player who reads the swing correctly and leaves the right creature unblocked on purpose. This is the inverse of the usual prevention template, where damage simply vanishes; here the damage has to land somewhere, and the choice was to send it upstream. Instant timing makes the window the declare-blockers step: hold it up, invite the attack, and convert an opponent's tempo play into a sudden lurch in the life totals. It belongs to the lineage of damage-redirection effects rather than the prevention spells it visually resembles, and that distinction governs how the whole card plays: not a wall, but a counterpunch waiting on the right misread.
