Scattershot Archer

Green has always owned anti-flying technology: it fields the largest ground creatures and is the color least able to chase down evasion, so the pie hands it Hurricane-style sweepers, reach bodies, and one-shot Plummet effects to compensate. What separates this Elf from those is repeatability without a mana sink. Each turn, tapping it deals one to each flying creature on the board, which makes it a recurring sweeper rather than a single answer. Against a swarm of 1/1 flyers (tokens, Faeries, the cheap evasive starts green struggles most to interact with) it functions as a standing wall and a repeating board-wipe at once, asking only that you leave it back. The discipline is in the one-damage cap: it taxes go-wide token plans hardest and shrugs off anything with two or more toughness, so a single fat flyer eats a ping and keeps coming. It does not touch the ground and blocks for almost nothing on its own. That narrowness is the price of a repeatable answer in green at all: a one-mana body that converts into a permanent, free-to-fire deterrent against exactly one threat profile, and is dead weight against every other.
