You can be magical and astrological with this ingenious effect! Offer an audience member a brief astrological reading, showing that a deck of cards can be used as a calendar. Four suits--four seasons; thirteen cards in each suit--thirteen phases of the moon in one year, fifty-two cards in the deck--fifty-two weeks in a year. During the reading you begin to show the prediction cards that you were compelled to pick before the show, and explain their purpose in the astrological procedure. Then, for the finale, you show that your prediction cards match the spectators birth date!
