Metropolis Sprite

The pump ability here is a knife that cuts toward its own grave: every blue mana adds a point of power and subtracts a point of toughness, so you sharpen the clock at the direct cost of survival. With a 1/2 base, one activation makes it a 2/1 flier; a second tips it to 3/0, where it fails the state-based check the moment the ability resolves and falls off the battlefield. That ceiling is the whole tension. The card asks you to read the board and decide how much evasive damage you actually need, capping its useful output at two in the air, before the third point of power becomes a death sentence. Because the toughness loss lasts the turn, the sink doubles as a way to commit it fully on a swing you do not expect it to survive. Note what the math does not buy: raising power while toughness falls walks the body toward both halves of most conditional removal, so this is no protection trick. A small blue evasive body sitting behind an on-board mana sink, it chips in for one or two a turn while leftover mana holds up interaction. The Rogue type and flying point it at a tempo-oriented aggressive deck rather than a controlling one: it wants to be attacking, and the +1/-1 is the accelerator you reach for when the opponent is low and the arithmetic finally favors raw power over staying alive.
