Thornbow Archer

The attack trigger runs backward from how tribal aggressors usually work. Most reward you for fielding your own creature type; this one keys off the opponent's board instead, costing each opponent who fails to control an Elf a point of life every time it swings. That puts the card's reach entirely in the opponent's hands: against a creature pile that happens to have an Elf down, or in a mirror, the trigger does nothing, so a swing at a deck with no reason to run Elves is where the point actually lands. The asymmetry keeps the clock honest. It is not a guaranteed point of reach, it is reach conditioned on how far the opponent has strayed from your tribe. The 1/2 stat line handles the rest: it trades the customary one-drop point of power for the toughness to survive the small pings aggressive shells throw at each other, so the attacker keeps coming back to chip away rather than getting traded off after a single swing. It reads small and is, but the structure is deliberate: a recurring point of life loss that scales not with your own development but with the opponent's distance from playing the same creatures you are.
