Daring Thief

The whole Donate archetype, compressed into a creature that fires on a clock you control. Where Donate and its descendants ask you to give an opponent something they regret owning, this asks the opposite: it takes the best thing on the other side of the table and hands over your worst, repeatedly, as long as it keeps untapping. The type-matching clause is what stops it from being unrestricted theft. You can swap a token for their bomb only if both share a card type, so the engine wants a stable of cheap, expendable permanents that line up against whatever the opponent is playing: an enchantment for an enchantment, a creature for a creature, a worthless artifact for a Sword. Inspired ties all of it to the untap step, which gives the card a peculiar tempo demand: the body has to tap first and then untap, so you either attack with a fragile 2/3 and survive the swing back, or tap it for some other purpose and let your untap step rearm the trigger. Building an artificial untap loop turns the swap into a recurring grind that strips an opponent's board down to its scraps. It is a build-around in the truest sense, a payoff that does nothing until you assemble the deck of decoys it wants to trade away.
