Wing Puncture

Green's classic problem is the airspace: it builds the biggest creatures on the ground and then watches them get chump-blocked or flown over while a winged 2/2 runs away with the game. The usual answers are blunt (Plummet, Hurricane, reach creatures), but this takes a sharper route, conscripting your own ground-pounder's power into a guided missile aimed only at flyers. The instant speed is the whole point: you hold up one mana and dare a flier to attack or block, then convert the full power of an idle creature into reach it never had. It is a fight that only goes one way, which sidesteps the usual green fight-spell tax of risking your own creature to a counterswing, but the cost of that asymmetry is the rigid target requirement. There has to be a flier on the other side, so it is dead in any board state without one, and it does nothing if your largest creature is small. The design sits in a long line of green anti-flying tools that trade flexibility for color-pie discipline: green is allowed to punish flyers, not to gain the keyword itself, and this hands the job to the muscle green already has on the table. Read the power off your biggest creature and you have a one-mana removal spell; read it off a 1/1 dork and you have a cantrip-less misfire.
