Remove four aces and one five. It doesn't matter which five. Place the five, face up, on the bottom of the face-down deck. Place the four aces face down underneath the five.
You should have a face-up five and four face-down aces all the way at the bottom.
Spread the deck in your hands, being very careful not to show the bottom cards you previously set up.
Have the spectator pick and remember a card. Have him then place the card on top of the squared-up deck.
Cut the deck once he places his card on top. This moves his card right underneath the four aces.
With proper patter, spread the deck across a table and blatantly point out the face-up five.
Be sure to explain that this must be a clue and an indicator.
Count five cards to the left of the five and turn the fifth card over. It will be the spectator's card. For added effect, move past it and then come back.
Once he thinks the trick is over, turn over the four cards in between to reveal they are all aces.
