Sire of Stagnation

A punishment card built around the most mundane action in the game: playing a land. The trigger fires on every land entering an opponent's side of the table, on both players' turns, and the asymmetry is the entire engine. They exile two cards from the top of their library; you draw two. Against a deck leaning on fetches, ramp, and extra land drops, the draws compound fast enough to swamp someone in raw advantage without a single attack. The 5/7 frame is deliberately defensive rather than threatening: this is a tax collector built to survive, and seven toughness is sized to shrug off the midrange damage that would otherwise let an opponent ignore the trigger and race past it. The exile on their end is incidental attrition; the two cards you draw are the point. The design problem it solves is how to punish lands without writing "whenever an opponent plays a land," which would miss anything that enters without being played: by keying off any land entering an opponent's control, it catches token lands, copies, and recursion that a narrower clause keyed to the play action would never see. Devoid keeps it off the removal that hates colored permanents while leaving it exposed to colorless answers, a quiet bit of color-pie bookkeeping rather than a perk you build around.
