Ondrej Pšenicka Butterfly Deck With the Butterfly deck, you can perform miracles that no other deck can. A true innovation in card magic.”- Richard Kaufman The unique marking system hidden in the back design of the Butterfly playing cards contains two different marking systems that can be used separately. The deck of cards is signed by its creator, the original author. Ondrej Pšenicka It began as a simple fascination with one-way decks, but became an obsession. The result is a truly unique advancement in card magic, one as elegant and beautiful as a butterfly. It’s a pleasure to introduce you to Butterfly Playing Cards. It’s a challenge to create a deck that is complex enough to hide marked cards without being too irregular and cluttered, but the Butterfly Deck was designed with an exceptional amount of care and thought, fulfilling its function while displaying a beautiful design. Each card is edge-marked in two ways, allowing you both to locate any card in the deck via the two-way edge marks and to spot any reversed card using one-way marks on either the backs or faces. For the first time, the Butterfly Deck has made these two systems practical and accessible and you will be able to perform miracle-class effects. You’ll very fairly be able to divine selected cards, determine what cards are missing from the deck, how to deal the cards quickly into separate red and black piles, and so very much more. And heaven help the spectator if you know a memorized stack as well, because using the Butterfly Deck with a nem deck is just patently unfair…for the spectator, that is. They’ve got no chance at figuring out what is going on.
