A selected card is shuffled back into the deck. A small packet of baseball cards is shown to be all different. After mixing the cards, the top card is shown on both sides to be a baseball player swinging a bat. The spectator inserts the baseball card anywhere in the deck.
He is told that the baseball card will find his selection. The cards above and below the baseball card are checked and found not to be the selection. For a startling conclusion the baseball card is turned over to reveal that the player in the picture is now holding the selected card instead of his bat. Comes complete with ten baseball cards (use your own deck). Can be repeated.
Very easy to do.
