This trick can’t be conducted properly unless you rip one piece of paper into thirds, so make sure you prepare for it by having a large sheet of paper on hand. Pay attention to the person who has the piece that is ripped on both sides. This piece of paper is the key to the trick.

Make sure no volunteers are too close to you while you’re writing down the names, or they’ll see what you’re up to. If you’re doing the trick at a birthday party or an event to honor someone, you could also simply write down the name of the honored person on every card, to ensure that he or she is named the “luckiest” person there. Instead of saying you’re predicting who is the luckiest person, you could say you’re predicting who will get married next, who’s the most mysterious person, or who’s the unluckiest person. Tailor it to the event and the people.

Come to your show with the card box already prepared. Keep the side with the hole away from the audience as you prepare to perform the trick. If you can find a box that has a picture of a playing card printed on it, as many standard decks do, all the better - the hole will barely be visible.

He or she will almost certainly place the cards into the box face down so that you won’t be able to see the chosen card. If not, tell him or her to start over and pick a new card.

Note that this is the most important part of the trick. Without carrying out this step, you will not be able to perform the trick.
