If I have {essence of the wild} on OTB and I bring out a {reassembling skeleton} who now is a 6/6 copy. If its killed And goes to GY can I use the {reassembling skeleton} ability to bring it back? I guess what I'm asking is it still a copy when in the GY
Yes cause it's no longer {Essence of the Wild}. It returns back to {Reassembling Skeleton} just like transformed cards return back to the front side or {clone} cards return to there oringinal state.
It will go to the GY as the skely so yes you could bring it back.
Nice
