Note from Don: I saw Tom Craven present this trick early on in my magic years. Simple to perform.
Effect: A deck of cards is shown to be shuffled. One spectator chooses an even number, and another chooses an odd number. Those numbers are counted down to and selected cards are looked at by spectators. Cards are replace anywhere in deck, and is given a riffle shuffle. Magician then is able to find the two selected cards.
