Is there a card trick where there is a deck of 52 cards with each card a different back design, all are from different decks. and they all have different fronts, which are normal face cards and numbers (and suits). You have a envelop with your prediction and ask the guest to take too cards and pick one with the back and the other for the number. then you open the envelope and in there is a single card with the same back and same number of the other card. If there is a card trick please send me a link please.
