Dave Deck by Greg Chipman (Download)

The spectator is given a deck of cards to hold or place on the table. They are then invited to think of ANY card in the deck. The magician takes out a business card and writes the name of a card on its reverse, which is then given to the spectator or put in view of all. The spectator now reveals what card they were thinking of; let's say the six of diamonds. The magician, with a confused look, then invites the spectator to read his prediction, to which they read "DAVE" on the back of the business card. The magician then says he thought the spectator was going to give their card a name, rather jokingly, such as John, Barry or even Dave, not the actual name of a card (6 diamonds). The confused spectator thinks the effect has gone wrong, but this usually gets a laugh especially when performed to larger groups. The magician then says he will perform an effect with the card they said (6 of diamonds) to make up for the mistake. The magician takes the deck the spectator has either been holding throughout or has been on the table from the start and finds the selected card (6 of diamonds) and places it on the table. All the other cards in the deck are then shown to be normal, and the spectator's selection is the only card that bears the name DAVE either on the face or the reverse of the card.

Once a Dave deck is created, it will last as long as the deck lasts through general wear and tear. The deck also only takes a few minutes to set up, so multiple decks with different names could be made.
