Progenitor Mimic
{4}{G}{U}
Creature — Shapeshifter
Oracle Text
You may have this creature enter as a copy of any creature on the battlefield, except it has "At the beginning of your upkeep, if this creature isn't a token, create a token that's a copy of this creature."
Watch Out
Copies don't copy everythingWatch Out
Copies don't copy counters, equipment, auras, or other external modifications. A copy of a transformed card copies only the front face. If the copy enters the battlefield, it triggers its own ETB abilities.
