Imagine spreading a deck of cards face up on the table. Imagine picking the cards up and riffling them while a spectator visualizes a card. The spectator is then asked a question or two about his card. Is it red? Is it a low card? At that moment the selected card begins to rise from the deck.
As difficult to do as this effect sounds, it is extremely easy with this gaffed mechanical deck. The deck comes in the standard Bicycle design. The entire effect has a five to ten minute learning time.
