Dimir Doppelganger

A 0/2 body that mugs the graveyard for its own statline. The clone here works differently from the snapshot copy effects most players know: instead of duplicating a creature on the battlefield, it reaches into any graveyard, exiles a creature card, and repaints itself as that creature, keeping only the activated ability. That last clause is the entire engine. Because it retains the ability after copying, it can do this again and again, becoming a 6/6 one turn and a utility body the next, recurring as graveyards refill and shedding the previous identity each time it fires. The cost is that it never improves on its own: a 0/2 that holds still until you feed it, and every transformation is a repeatable mana sink rather than a one-time event. The graveyard requirement also makes it parasitic in the literal sense; it grows fat on what an opponent buries, turning their best creatures into your own and exiling them out of recursion in the process. It is a Shapeshifter built around repetition rather than the single decisive copy, and it asks for a board where creatures keep dying so the ability always has a target. The design lineage runs through the old Vesuvan Doppelganger school of "become a creature" effects, but the exile-from-graveyard hook and the self-preserving ability mark it as something more recursive: a clone that never settles, only the next thing in the yard.
