Pyre-Sledge Arsonist

The value X is deliberately amnesiac: it counts only permanents you've sacrificed during the current turn, resetting to zero on the spot every turn, so there is no counter to accrue and no ledger of past sacrifices to draw down. A turn where you throw nothing away is a turn where the ability deals nothing. That refusal to store value front-loads the whole payoff into a single burst, which is what keeps a repeatable, any-target damage source at this cost from running away with a game. The design's real point of interest is where it sits in the aristocrats stack. Most sacrifice engines reward the death itself (a drain trigger, a token, a scry) and treat the spent permanent as spent. This one treats the corpse as ammunition, converting the raw count of things you were willing to give up into direct damage pointed anywhere, which folds a removal outlet and a reach clause into one activation. The cost to fire it is minimal once a sacrifice loop is already turning, so the arsonist becomes the muzzle you aim at whatever needs to die: a blocker, a planeswalker, or a face. It asks nothing of you except a board worth feeding and something to feed it into; supply the fodder and the outlet, and this is where the pile you built cashes out.
