How long does The Mimeoplasm remain a copy of a creature outside the game?
Asked by dylanjcarr 4 years ago
Since copying a creature is a prerequisite for its existence, would it maintain that identity for a full turn cycle?
Apparently undying and persist would bring it back but that's during the same turn.
It only stays a copy until the next time it changes zones. When a card changes zones it becomes a new object with no relation to what it was before, minus a few exceptions to make certain kinds of effects work properly. Since Phytotitan, like Undying and Persist, triggers when the creature dies, and doesn't depend on having the ability while it's in the graveyard, a Mimeoplasm pretending to be Phytotitan will come back from the graveyard if it dies.

The Mimeoplasm is only a copy when he's on the battlefield (if you used his optional ability). Clone spells generally work this way - they are only cloning something in one specific zone. When they change zones, they are no longer a copy of whatever they were before.
However, note that when he died, Mimey was a Phytotitan. The trigger from Phytotitan triggers when he dies, so even though he isn't Phytotitan once he enters the graveyard, the trigger was still activated, so he still comes back if he can (when the delayed trigger bit occurs). You'll have to pick something else for him to clone when he enters the battlefield, though, or he'll immediately die due to being a 0/0 ooze.
Undying and Persist work basically the same way - he had them when died, so the trigger works, even if he doesn't still have them when he hits the graveyard. I'm a little more vague on those.

The first version of my post was wrong. If you haven't yet seen the edited version, please go back and read it.
