Match The Cards
The Magician places an envelope on the table explaining that it contains a prediction card. Next a deck of cards is freely shown to have different faces and back designs. With the cards spread face down, one spectator freely selects a card, then the cards turned over and another spectator takes a face up card. When the envelope is opened and the prediction removed, the spectators are quick to point out that it matches neither card, then the Magician has a brainwave and shows that it does actually match both cards, on their other sides.
