The Ninth Card

Effect: You divine the identity of a selected card.

Secret: This is how to make someone take the card you want. Secretly place the card you decide to use ninth from the top of the pack. Ask someone to call a number between 10 and 20. Count that number of cards, one at a time, from the pack. Add the digits of the chosen number. Deal that number of cards off the cards just dealt. Ask someone to look at the next card. It will be the card you placed at ninth position. You can reveal it in any way you wish.
