This is no medical miracle. It’s 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! Tomas Medina, creator of the Cardiologist Deck, gives you all the details on how the deck works, from a detailed anatomy to its inner-workings. There is no fumbling, no special memory work, no riffle-shuffle technique or complicated sleight of hand to learn. In fact, using the Cardiologist Deck is so dead easy, a first year medical student can do it.
