Irma, Part-Time Mutant [Teenage Mutant Ninja Turtles Commander]

Cost: 2 U At the beginning of combat on your turn, Irma becomes a copy of up to one other target creature you control, except her name is Irma, Part-Time Mutant and she has this ability. Then put a 1/ 1 counter on her. I'm not trying to cause trouble. Trouble just follows me around.
