To set yourself up for this trick you must first take a plain deck of cards and slit it anywhere. Then flip the top card on the bottom half from the bottom half of the deck. Memorize the card and put it back into the deck. Keep cutting the deck several more times. Once you are ready, with the deck face down, pick a number between one and ten. Then draw that many cards and then flip your spectator's card.
You first must place the ace through ten on the bottom of your deck. From this point, after your spectator chooses a card you will place the ace through ten on top of their card. After you cut the deck (face side up) you will want to look for one of your suit cards. Once you find one, memorize the card and "randomly" pick that number (of the card you came across while cutting the deck). Finish your last cut, and draw that many cards. Your spectator's card should be the final number.
