Turnkey • Dis • Creature • Rare • Play: Unforge an opponent’s key. If you do, when Turnkey leaves play, your opponent forges a key at no cost. • Artist: Felipe Martini • Card Number: MM:051
The Play: ability of Turnkey resolves and creates a lasting effect. This effect remains as long as the creature is in play, and the effect does not change if control of the creature changes.
