Predixion is so powerful because it is so simple.
Here’s what happens:
Two decks of cards are used. One is given to the spectator and one is on display the entire time.
The spectator deals a pile, stopping at any time. He then separates that pile into two piles. Then, a card is selected from those two piles. This all happens in the fairest way AND it happens completely hands off. After the spectator verbally chooses the card, it is shown to be predicted inside the deck that was on the table the entire time.
No difficult moves
No gimmicked deck
Spectator makes all the decisions
The effect is hands-off during the entire time.
