Depending on the gimmick that you are using, make the card in either The Good Guess or Simple Monte vanish, according to the instructions.
After vanishing the card, pull out the deck of cards and allow the spectator to discover that the vanished card has traveled to the deck and reversed itself.
Tip:
You dont have to make the card travel to a deck of cards. For example, you can have the "vanished" card in your pocket at the beginning of the trick. At the tricks conclusion, you can show that the card traveled to your pocket or any other place.
