This is an entertaining, commercial trick bearing a mystery card plot, with the spectator playing the magician and a color-changing finale that packs a wallop.
The spectator shuffles and selects a card from a blue deck under test conditions. This is the prediction. The magician shuffles the red deck, chooses a card, and signs it. The signed card miraculously matches the prediction. As a kicker finish, the magician causes the signature to jump from the red card to the blue card.
