Yeah I am pretty sure they're all common and there is 81 cards but I thought there was 9 in a pack. if there are 9, 81 divided into 9 is 9 so I think if I don't get any doubles in a pack I would have to open 9 packs to get one. That's to say you don't get any doubles which is probably is not likely. So hopefully I'll get one in the first 5 or 6 packs that I open and not 12 to 15 packs.
