Brainwave Deck

The Brainwave Deck is a Mechanical Deck similar to the Invisible Deck but with an extra kicker. The deck is spread face-down and the named card is the only one that's face-up. As a second climax to the trick, this card is turned face-down and shown that its back color is different from that of the rest of the deck, thus proving that that the magician really did know what the spectator would say in advance and didn't just secretly turn the card over.
