Here's how it goes... two (regular decks are shown - black and red). A card is FREELY selected by a spectator. (No force!) The value of this card is only known by the spectator. Not only does the performer correctly name the card, but also tells the spectator the numerical location in the second deck that the spectator is holding in his hand.
Handmade gimmick does all the work and what a gimmick! Even IF you don't like card tricks-you'll enjoy this one! Use your own cards!
