The cards change. Double check it and you will find that the numbers of the cards stay the same but the suits change, for example the 9 of spades becomes a 9 clubs. Every card from the first group changes to a different but similar card in the second group. So no matter what card you pick, it will always be gone, since every card is changed. But they do look similar to the originals, since the changes are minor and hard to spot.
