text: During the cleanup step, Renegade Doppelganger's copy effect wears off. It will go back to being a 0/1 blue creature named Renegade Doppelganger, and will have its original ability again. Note that this happens at the same time that damage marked on the Renegade Doppelganger is removed. If it was dealt damage earlier in the turn, this damage will not cause Renegade Doppelganger to be destroyed when its copy effect wears off.
