Mimeoplasm, Revered One

The original Mimeoplasm asked you to eat two creatures and become one of them, wearing the other's power as counters: a single, greedy transformation locked in at cast. This version restructures the whole premise around repetition. The X-cost exile sets up a pool rather than a single body, and the counters scale with how many creatures you feed it, so the graveyard investment reads as a total rather than a pair of best-in-slot picks. The real shift is the activated ability. For two generic mana it copies any one of the exiled cards, and it keeps the ability, which means the copy is never final. You can toggle from one exiled creature into another as the board demands: a bigger body this turn, a keyword-laden shell the next, whichever static ability or evasion the matchup asks for. Because copying is a state change and not a new entrance, it never re-triggers enters-the-battlefield abilities: this is a toolbox of bodies and printed abilities, not an ETB engine. The 0/0 clause is the discipline holding it together, because each copy overwrites the copied creature's base power and toughness, leaving the +1/+1 counters it entered with as the only thing keeping the Ooze alive. That reframes deckbuilding around the graveyard as a modular kit: not the two fattest creatures you can mill, but a spread of exiled cards whose abilities you want to rotate through. Where the older design was a one-time payoff, this one keeps asking which creature you need to be right now.
