Two simple decks to test your perceptions and perform a little miracle.

Imagine to shuffle the first deck, then ask the spectator to create three piles, shuffle the first one and remember the top card.
The card is then lost in the deck and you, running throught the cards without seeing their faces, will be able to feel the spectator's card using your perceptions.

In addition, you will tell the spectator that you trained yourself with the second deck, with a specific card, the same card choosen by the spectator. To demonstrate this you marked the card with a cross on the back. it will be the only marked card in the second deck.
