The Crossroad by Alex Pandrea
The spectator merely thinks of any card in the pack and names it out loud. The cards are shuffled up by the spectator 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 in which they don??t think their card is in. This happens multiple times until you are left with two cards only. The spectator is asked to chose 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 spectators chosen card. This effect is easy to do, super powerful, and very practical. This is card magic at its finest!
