Do As I Do
The spectator shuffles the deck and cuts it in half, giving half to the magician and keeping the other half. The spectator then does everything the magician does – choosing a card, swapping cards with the magician, then putting it back in the deck. When the deck is spread out, two cards are reversed – the magician’s card and the spectator’s card.
