Bane of the Living

A board wipe usually announces itself: you tap out at sorcery speed and the whole table watches you pull the trigger. This one wears a disguise. Cast face down, it sits among the other 2/2 morphs as an unreadable threat, and only when its controller pays the unmorph cost does the battlefield collapse, at instant speed. The scaling is the lever: X is set by the morph cost, so the same Insect can be a surgical -2/-2 against a low curve or a -6/-6 reset that clears nearly everything when the mana is there. The math hides a catch. The sweep is symmetric, and with toughness 3 the Bane only survives when X stays below three; push X higher to clear a fattened board and it dies with the rest, trading a creatureless reset plus a 4/3 for just the reset. That choice, how wide a wipe against whether you keep the body, is the entire decision. The morph shell does work even unflipped: the mere possibility of hidden mass removal taxes how an opponent commits to the board, shaping their attacks in a way a known sweeper sitting in hand never could. Among early morph designs that turned the face-down bluff into real strategic pressure, this one weaponizes the uncertainty most directly, because the thing being concealed is not a single threat but the answer to the opponent's whole board.
