A funny routine to perform and watch! A card is selected from the deck. Say it is the 10D. The magician then says he needs four chances to determine the card. He brings out a packet of four cards and shows they are all 10D. But then he shows the fronts look like the backs-all the cards have backs on both sides. Now all the cards become blank on the face, then the 10D makes its appearance again to end the routine! Easy to do. Complete with all the cards.
