Isolation by Jeff Pierce
Item Number: LP6859
A freely selected card, picked from a small group of cards is placed face down on the table. A number is selected by another spectator. The magician counts down in the deck to that randomly selected number, and that card is shown to match the card selected by the first spectator.
The kicker is revealed when the deck is spread face up on the table and all the rest of the cards are totally blank!
