X-Factor by Ron Frost and Meir Yedid Magic
"X" -ceptionally visual magic that will stun your audience!
A selected card is lost in the deck. You remove a four of a kind from the deck which includes the selection. The faces of the cards are clearly shown as the card thought to be the selection is placed to one side. Employing the "X-Factor" you begin to verify the selection's identity by showing that the other three cards now have a big, black "X" emblazoned on their faces. The mind-blowing climax comes when the selection is turned over to show that it not only has a big "X" across its back but that back also changed color!
This is visual, easy-to-do, easy-to-reset magic, perfect for the strolling performer. Comes with special Poker Bicycle cards and photo-illustrated instructions, use your own deck.
