Ashen Firebeast

A repeatable Pyroclasm bolted to a body that soaks its own blast. The math is the design: each activation pings every creature without flying for one, and at six toughness the Firebeast can keep firing for several turns before it burns itself out. That makes it a one-card attrition engine against go-wide ground decks, the kind of top-end finisher that wins by outlasting rather than racing. The seam in the armor is right there in the text: flyers walk between the raindrops, so the sweep is board control with a permanent blind spot rather than a true wrath. Eight mana for a 6/6 with no evasion and no immediate impact is a steep entry price, and the activation cost compounds turn over turn, but the payoff is a slow, inevitable clock that doubles as removal. It comes from a design school of expensive, do-it-yourself control creatures: the fatties you played because they did a job no spell could repeat. Not a single sweeper but the standing ability to sweep again next turn, and the turn after that.
