Impossible Man

Clone effects have almost always been permanent commitments: you resolve one, pick a body, and that is the shape you keep. This design breaks that contract. Copying is an activated ability here, not an enters-the-battlefield trigger, and it wears off when the turn ends, which means the same 1/4 flyer can wear a different face every turn. A mana rock this turn, a lethal attacker the next, a copy of whatever an opponent just resolved after that. Because the copy preserves only his name, he sheds his own abilities the moment he transforms, so each turn's shape is a single, deliberate choice. Because the ability targets any permanent, not just creatures, it reaches artifacts, enchantments, planeswalkers, and lands, a far wider net than the creature-only clones that defined the archetype for years. The self-referential clause (he keeps his own name no matter what he copies) is a precise bit of engineering: it prevents legend-rule collisions when he mirrors another legendary permanent, and it keeps the Impossible Man identity intact underneath every borrowed shape. When he isn't copying anything, that flying 1/4 is a durable blocker that holds the board until you decide what to become. The whole card rests on a genuinely Shapeshifter-flavored premise: that becoming something is a choice you get to remake, not a decision you live with forever.
