Get three jacks from a standard deck and one card that is not a face card. Make a gimmicked card by taking the non-face card and cutting it in half, then reattach the two halves with tape. The top and the bottom of the card are now touching. Put the gimmicked card over the top of the middle jack so that when you fan the cards to the audience, it looks like the non-face card is situated in the middle. Show the audience only the top one-third of the cards, front and back, making sure to cover the gimmicked card.
Place the cards face down on the table, making sure to keep your palm facing down. When you pull your hand back, you should have secretly removed the gimmicked card, leaving only the three jacks. Once you have the gimmicked card off the table, you can reveal the three jacks and amaze your audience.
Prepare for this trick by removing all the tens and face cards from a standard deck. Ask a member of the audience to shuffle the deck, and then fan the cards out in front of the person and ask him to pick a card. Ask the audience member to memorize the card and replace it in the deck. Tell the participant to multiply the value of the card by two, add five and then multiply the total by five. Have him remember the total and then pick another card from the deck, adding the value of that card to the previous number.
Let the participant reveal the total of all these calculations. Subtract 25 from that number, in your head, and you will have the value of both the cards the audience member chose. For example, if you subtract 25 and your total is 48, their cards were a 4 and an 8.
Ask a member of the audience to shuffle a standard deck thoroughly, and then have the person name two cards. You only need the number, you do not need to know what suit. Place your hand over the deck and act like you are concentrating very hard. Wait a minute or two, then ask the participant to turn the deck over and fan the cards to show them to the rest of the audience. The cards the person named will be next to each other. You do not have to do anything and this trick works approximately 90 percent of the time.
Because the person only named two cards and not the suit, there are four of each type of card and there is a high probability that, out of those eight cards, two of them will be next to each other or separated by one card. If the two cards are separated, you can always claim you did not concentrate hard enough.
Have an audience member shuffle a deck of cards and then count off any number of cards, as long as it is under 15. The participant looks at whatever number card he chose, remembers it, and puts it back in the same place. Make sure your back is turned during this, and then turn back to the audience. Take the deck and, with it behind your back, count 15 cards off the top. Be careful; do not reverse the card's order. Ask the participant to transfer as many cards from the bottom of the deck as he or she chose from the top. Take the deck, again behind your back, and transfer 15 cards from the bottom to the top. Reveal the bottom card, which should be the audience member's card, as magically as possible.
