Stunning Mental Card Magic!
The spectator is asked to merely think of one of the four kings. There is no force of cards.
As the spectator thinks of the card, the magician removes a pay envelope from his pocket. Inside the envelope, the magician, are four cards. Once looks different from the other three.
The difference is this: The card thought of by the spectator is reversed. It also has a different color back than the other three cards. A miracle!
No sleight of hand. Immediate reset. Works every time.
