Effect
The performer presents a deck of cards that has been mixed up; some cards facing one way, some facing the other. He spreads them on the table, asking the spectator to choose any face up card, and return it to the deck, face down. The performer then collects the cards and begins to shuffle and cut the deck, magically altering the deck so that all the cards are facing the same way! When he spreads the cards on the table again, all the cards are facing the same way, minus one: the spectator's card!
