Thieving Sprite
The discard scales with your board, not your hand, and that single inversion sets it apart from the dozens of fixed-size hand-attack creatures black has printed. With one Faerie in play (this body counts itself, so X is typically at least one), the opponent reveals their chosen single card and discards it: a Ravenous Rats with wings, not the surgical strike of a Coercion. The opponent picks which cards to show, so a small X is a tax, not a scalpel. The math turns once the swarm is online. Reveal four cards and the chooser's edge erodes: when most of a hand is on the table, the controller is the one selecting from it, and the discard becomes the targeted removal of the sweeper, the blocker, or the answer to a clock that an evasive tribe is already pressing. The asymmetry is the payoff. Conventional black disruption trades a card and cedes board position; here the flying body is already part of the offense and the discard rides along on the trigger. It belongs to a school of Faerie reward effects that convert raw creature count into disruption, the kind of trigger that reads as filler in isolation and quietly empties a hand once the deck has done the work of flooding the board with cheap evasion.
