The magician shows his cards to a spectator, who thinks of one of them quite freely. However, this card has been predicted beforehand, since the magician shows that there is only one foreign card in the deck (it is a card that has a different back to the cards in the deck), and it is indeed the one thought of by the spectator! Success is guaranteed! In the explanation Dominique mentions a new sleight, it is in fact the "Hitchcock Move" which you will find in the sub-category "My Techniques" of Dominique Duvivier.  

Your audience will experience a collective hypnosis exercise... that will go further and further! Three spectators will live an extraordinary experience... but what could be more normal, since they are under the hypnotic influence of the magician!  

A "Tsunami" of madness, based on a trick by Larry Jennings. A card is freely thought of and then lost in the deck under "laboratory conditions". The magician even has his back turned during all these operations!

Without asking any questions, the magician names the chosen card. The climax is incredible: the chosen card is the only printed card in the deck; all the other 51 cards are blank on both sides! Everything is given out for examination.
