Skyshooter

Reach plus a one-shot kill, fused into a single green two-drop that answers fliers in two distinct modes. Block one and trade with the body, or, when the math goes wrong, tap and sacrifice to remove an attacker or blocker outright. The sacrifice clause is the part that does the real work: green has always had reach to gum up the ground against fliers, but trading a 1/2 in combat caps out at killing one small flier per turn and only when the attacker obliges. Here the activated ability lets the creature reach past combat math entirely, destroying a flier of any size at the cost of itself. The strict gate is what pays for that flexibility: the target must be attacking or blocking, so this is not a roaming removal spell that picks off a dormant threat at sorcery speed. It demands the flier be committed to combat, which keeps green honest about its historical weakness to evasion rather than handing the color an open-ended answer. The result is a defensive piece that bluffs as a wall, then converts into a guaranteed kill the moment an opponent overextends into the air, with the body and the ability split across two different turns or spent in one motion depending on how the race is going.
