A great classic Card Magic is available again!
You explain that when you are facing an audience, your spectator is sometimes totally unknown to you.
One day, you asked a man to shuffle the deck, he does it, to cut it... and there, it was a mistake, because he was a butcher in his professional life!
You then present a game cut in half diagonally! You show that the 1/2 sides of the cards are all different, you shuffle the 1/2 deck, and the spectator puts his finger on a card of his choice. This card is set aside.
You repeat these actions with the other half of the cards, with another spectator.
When the two card halves are turned over, they match and form one card!
A real miracle, completely automatic!
