This is more than an effect. This is a crucial technique used in Shawn's act that has won him multiple awards from SAM, IBM, PCAM and FISM. You get a finely crafted block of plastic that has been laser cut and machined to the size of a deck of cards. Using this unique block (commonly referred to as an Omni Deck, crafted by Palmer Tilden) and Shawn's deck switch technique you will be able to present an incredible ambitious card routine that ends with the deck of cards magically turning into a block of plastic right in the spectators hands!
