This is a 'princess' style mental effect. Spectator receives a few cards, remembers one of them and then these cards are shuffled back into the rest of the deck. The performer shows groups of cards to the spectator until a group is identified that holds the spectator thought of card. The card magically travels from one packet to another packet exactly to the position that a second spectator cut to.
