The problem I have in my circle of players is about the possibility of stack his ability. We agree about the stack, but desagree about the way it resolves, because the card say that he turns into a copy, so when the second stack look for him to turn it again, in my opnion there isn't scion of the ur-dragon in the table any more, but a copy of anothe dragon, so the second stack fizles. Am I correct?
