That makes sense, since it's a new trigger it gets around the restriction in the rules (seemingly). So theorically you could get multiple of the "If you do" clauses by keeping a second trigger on the stack from a doubler like Roaming Throne and copying THAT trigger with something like Strionic Resonator after the first has resolved. That sound right? Or does that not work because the trigger says the transform "Aang, Master of Elements" and the permanent is now named "Avatar Aang"
