I was trading my cards with a friend and it said I gave her 7 cards in exchange for 4 cards! I thought you could only trade 4 at a time!!!!!!!!!!! If you know what happened please reply!!! I do not need to take them back I just want to know! Thanks in advance!
You can trade 4 types of cards, but multiples of each type. You can tell the number in the stack by the little black box in the bottom left of the card.
