Pocket Appearence

Effect: A spectator picks a card, it then disappears and then reappears in the magician pocket/wallet.

Preparation: Take one card from one pack and put it in your pocket. You will no longer need that pack. Put its twin from the other pack on top of the pack.

Riffle force the top card. Reassemble the pack and give it to the spectator, telling him to put his card in it and shuffle the deck. Take the pack and announce that you are going to find his card. Look through the pack, cut at the chosen card while saying you cannot find their card, then palm it away. After looking through the pack claim that you cannot find his card (although in fact you should have already palmed and disposed of it unnoticed). Then say something like "Hang on, what's this in my wallet?" and pull out the card . This is a slightly easier way to get rid of the duplicate card. When you're supposedly looking for the card, if you cut it to the top of the deck, it's fairly easy later to palm it off and get rid of it.
