Split the Party

Bounce spells usually come in two shapes: the single-target answer that clears one threat, and the sweeper (Evacuation, an overloaded Cyclonic Rift) that resets an entire board at once. This one lives in the gap between them, scaling its swing to whatever the target has committed rather than a fixed count. Rounding up is the detail that gives it teeth: against a lone attacker it returns that one creature and empties the board, and against odd numbers it always claws back the larger portion (three of five, four of seven) while leaving the opponent something to replay. It can never fully clear a board of two or more, which is the point; its natural target is the developed board it can only partially unwind, where it slows the curve instead of resolving it. The sorcery-speed restriction closes off the reactive lines that would make it a blowout: no fog, no combat trick, no end-of-turn ambush. You spend your own turn on it as a proactive tempo play, which pins its home to a controlling deck willing to trade a turn for a partial reset. It answers development without committing to killing anything, a distinctly patient way to handle a growing threat count: buy time, then close under the tempo swing while the opponent rebuilds.
