I was able to emulate Wonder Card with a Pokemon distribution rom. During my testing process I got by mistake a Japanese Event Mew, which now of course prevents me from getting the NA Anniversary Mew.
I want to know If I can get another one via Mystery Gift, if I deleted the card and release the pokemon, or if there's another way.
Note: I still dun have a AR so I can't use Pokesav to get my save from DS and edit.
