Place the 4 aces on the top of the deck. Have the spectator
choose a card. Quickly count off 12 cards and have the card
replaced so it is the 13th from the top. Now, tell the
spectator that you have memorized the deck and know that their
card is in the top half. Begin dealing two piles three cards
at a time. Once you have dealt 24, add one to each. Discard
the remaining cards. Tell the spectator their card could be in
any pile. Pick up the one on the left and grasp the deck at
the edges with on hand and top and bottom with the thumb and
middle finger of the other hand. Pull so that you remove the
top and bottom cards. Place these on top. Take the right deck
and use a little patter while overhand shuffling so that the
bottom card becomes the top. Now, you should 2 aces on top and
one on the bottom of the left deck, and an ace on top of the
right. Now place your hands on the decks and magically say you
know it is on the left. Push the right deck forward. Deal the
remaining deck one by one into two piles. Places your hands on
top and discard the left. Deal the remaining cards into two
piles. Place your hands on top and discard the right. Deal the
remaining cards (you should have 3) into two piles. Discard
the left. The remaining card is the chosen one. Now, most
people know you simply counted where it was, using some
patter, amazingly flip over the top cards of each of the 4
piles in front of you producing the 4 aces. Use good patter to
make this more exciting.
