It39s simply a diabolical deck of cards that lets you operate like a master magician!The Cardiologist Deck can be shuffled by both the magician and the spectator at any time. Even so, the magician can instantly, without complicated sleight of hand, find the mate of any card freely selected by the spectator. No matter how often the cards are shuffled or by whom the magician can instantly pair up the entire pack with surgical precision!
