The paper is crumpled into a small ball and placed in their pocket . You now run through a regular deck and remove one card only. Without ANY questions the card is placed face down onto the spectators hand. For the first time they reveal the card out loud.THEY turn over the card it is exactly the card they I am thinking of.

ANY PEN, ANY PAPER, ANY DECK, NO QUESTIONS, NO SWITCHES OF ANY KIND. Can be repeated instantly.
