Pop-Eyed Popper Trick Deck
The performer asks a spectator to pick any card. Once a card is chosen, it is shuffled back into the deck. The performer snaps his fingers, and the chosen card returns to the top of the deck. To prove that any card in the deck can be moved, the performer then shows the top card in the deck and places it on the bottom of the deck. He snaps his fingers, and now the card has returned to the top of the deck!
