Kor Castigator
A 3/1 for two in white is aggressive shorthand: a body that races, dies to almost anything, and asks you to land hits before the ground stalls. The evasion clause takes that premise and shrinks its target down to a single creature type, the 1/1 tokens spawned by the era's Eldrazi. That is about as narrow as evasion can get and still earn the name: it does nothing against any other blocker, and on a board free of those particular tokens it reads as a vanilla beater. It is a designer's bet on a local metagame, a creature built to punch through one expected wall rather than to threaten the format at large. The Ally tag and Wizard line gesture at tribal payoffs, but the static can't-be-blocked-by clause is the tell: this was printed to give a fast white deck an answer to the specific board the surrounding set was busy creating, a piece of internal counterplay rather than a card with ambitions beyond its home environment. An undercosted, fragile attacker paired with an ability that only matters against one kind of blocker is a card engineered for exactly one room, and it rarely finds a reason to leave the context that produced it.
