Chinese Secret (Gimmick and Online Instructions) by Wiz Spencer

You have the cards shuffled by a spectator. You then bring out a Chinese fortune teller. You ask someone to choose a color, then a number from the available choices, then a further number; this number will be the spectator's selection. The whole process is controlled by the spectator. As an example, let's say the spectator chose the number 9. You invite them to take the cards and deal down to the ninth card. When you reveal the card underneath the number on the Chinese fortune teller, the card matches the 9th card in the shuffled pack. Very easy to do with a powerful outcome.
