David Blaine performed a trick ( he has only performed it once and it was around last year ) where he hands the deck to the spectator and asks them to name any card, he then tells them to cut the deck and turn over the card they cut to, it is their thought of card. Someone said this trick was by Juan Tamariz but I dont know, so if someone could give me the name of the trick and also where I can buy it/learn it/find it. I would really appreciate it
