Bumi Bash

Land destruction has always been a maindeck liability: the games where you need to blow up a manland or a utility nonbasic are rare enough that a dedicated slot rots between them, and drawing it against a normal creature deck is a wasted card. This design solves that old problem by grafting the situational answer onto a burn spell that scales with your land count, so the same card that punishes a creature-land late is the one you were happy to draw early. The damage mode ties its ceiling to how long the game has gone: four points on turn four already clears most of what has hit the board by then, and dozens of turns deep it becomes a blast that kills anything, since every land drop feeds it. That makes it a reward for board stalls rather than a punishment. The destruction mode gets relevant at exactly the point the burn mode is peaking, when the game has ground into a resource fight and the opponent is leaning on creature-lands and nonbasics. That timing is the real work here: instead of pairing a live spell with a dead insurance policy, both halves sharpen together as the game grinds long. A slow game gives you the large damage count and the clean answer to the exact permanents a grindy deck relies on, at once, from a single slot.
