Pierce the Sky

Seven damage aimed at a single kind of target: enough to erase essentially any flier that has ever flown, and nothing at all against the ground. That conditional is the entire pricing model. Green has always carried a hole in its color pie at answering the air; its tools tend to be reach creatures, fight spells that demand a body of your own, or mass effects that arrive too late. This is the genre that plugs that gap without breaching the wall green is supposed to hit: an instant-speed answer that is enormous against the thing green otherwise cannot touch and literally blank against everything else. The reach lineage is long (Plummet, Clip Wings, Broken Wings, and their many cousins), and most sit at the binary "destroy it" tier. Trading destruction for fixed damage cuts both ways: a flier with a damage-prevention shield or a toughness that climbs past seven walks away, where Plummet would not care, while an indestructible flier survives either approach (damage kills nothing that cannot be destroyed, and neither does a destroy spell). The seven is deliberately generous so the spell never wants for headroom against the dragons and angels it exists to shoot down, and the green-only, flying-only leash is what lets a green card hold that much burn at instant speed. Precise by construction: dead weight against a grounded board, decisive against the one axis green struggles to defend.
