The spectator merely thinks of any card in the pack and names it out loud. The spectator shuffles the cards as much as they want. The cards are then dealt into two piles on the table. The spectator makes all the decisions, eliminating the pack that does not contain their card, according to their intuition. This happens multiple times until only two cards remain. The spectator is asked to choose one card from the two, and is also asked to change their mind if they wish. When only one card is left on the table, the magician reveals it to be the spectator's chosen card. This effect is easy to do, super powerful, and very practical. This is card magic at its finest!
