The Predictor by Alex (Instant Download)

Effect: Mentalist writes a prediction and hands it to someone. Than he presents two decks of cards. One red and one blue. From a red deck a spectator deals any three cards face down. Than they place these cards anywhere in a blue deck in opposite direction. At the end it turns out that the mentalist has predicted what cards will be chosen and even predicts exactly on what positions they are in the blue deck.
