GION Deck is the fairest and strongest mental effect that fools laymen and magicians alike.

Effect
The magician takes out two cards out of a red deck of cards as prediction. Then he introduces a blue deck of cards and shuffles it to show the deck is well mixed.

The deck is given to a spectator and he/she shuffles the deck. He/she stops shuffling at any time and places the top card onto the table. Then the first spectator hands the deck to another spectator. The second specatator does the same thing as the first spectator did.

The red prediction cards match the freely selected blue cards.

Features
The magician does not touch the decks after he produces them. Everything is done in spectators hands. There is no complicated moves. They only have to shuffle the deck and place a card onto the table. Memorized deck system is not neccessary. Performer can do this effect in a very casual manner. Prediction cards are not switched. You can prepare a prediction in your favorite way. You should always carry the GION Deck with you.
