"The Butterfly deck will enable you to perform miracles not possible with any other deck. A true innovation in card magic." - Richard Kaufman (chief editor of Genii Magazine - the largest selling magic magazine in the world).The unique marking system hidden in the back-design of The Butterfly Playing Cards contains two different marking systems that can be used separately, but they will make you a miracle worker if they are combined.Here are some basic effects you can accomplish using The Butterfly Playing Cards:IMPOSSIBLE DIVINATION: The cards are shuffled by a spectator and the spectator selects one without you looking. The card is retrieved and the cards are immediately shuffled by the spectator. All without you looking. You take the cards back and without looking at the faces or spreading the cards in any way, you know instantly what card it wasKNOWING THE MISSING CARD: The cards are shuffled by a spectator, taken behind their back, they take one from anywhere in the deck and hide it in their back pocket. Nobody, including the spectator, knows the identity of the card. They shuffle the cards again and give them back to you. You'll know the identity of the card in seconds without looking at the faces of the cards or spreading the deck in any way.CUTTING TO ANY CARD CALLED FOR: The cards are shuffled by a spectator. They name any card they want and you are able to cut to that card without spreading the cards in any way.Imagine being able to perform feats only possible using a memorized deck, but with a shuffled deck of cards. The Butterfly Playing Cards enable you to see the positions of all the cards in a shuffled deck.An explanation of this written marking system explanation is included, as well as a link to online video instructions.DESIGNThe cards were designed with two main goals in mind. They have to be complex and irregular enough to disguise the markings. They have to be pretty enough to justify their use over a more common deck of playing cards.There are two different custom jokers and the ace of spades that are true to the overall theme of the back design. The rest of the deck has standard US faces as it is primarily intended for magic.The cards are printed by Cartamundi and are of the highest quality.Chris Kenner - This is a game changer.Daryl - This is the most ingeniously designed marked deck I have ever seen in my life!
