The exile rider is the whole reason to look twice. A creature that taps to deal one damage is one of red's oldest functional templates, going back to the earliest dragons and machines that flick out a single point a turn. What separates this one is the death replacement stapled to that ping: anything it kills gets exiled instead of dying, which quietly turns a slow chip-damage engine into clean answers against the things that punish ordinary destruction. Persist and undying creatures lose their counter trigger because they never reach the graveyard; recursion shells that want bodies in the bin get nothing to bring back. The catch is delivery rate: one damage per activation means most worthwhile targets need multiple turns or chip support to finish, and the 1/2 body is easily outclassed before the engine matters. The ping itself carries no timing restriction, so it can fire on the opponent's turn or in response to a spell, which lets it snipe a one-toughness target at the moment that target is most valuable. So the design lives in a narrow band: too small to clock or to hold a board, but a precise tool against a specific class of creatures whose value lives in dying. It rewards a deck already grinding the board to a halt, where one repeatable exile-flavored point per turn is enough to dismantle a recursion package piece by piece.
