This is The N-DECK MASTERCLASS, in which Daniel Madison teaches how to master The N-DECK / NEGATIVE-STRIPPER Deck: a deck of cards carefully modified by The Sleight Surgeon so that the ACES and JACKS can NEVER be lost, and found immediately by the performer… No matter how the deck is shuffled, no matter the different locations of those cards, you can find them instantly and control them to whichever position that you desire – to the top, to the bottom, ready to secretly deal or steal from the deck. You can also locate and control the Aces independently from the Jacks, so that they don’t interfere with each other, as the Jacks and Aces use the same concept in different ways.
