Aces In Their Faces by Bob Kohler

David Copperfield, Ricky Jay and countless other professionals have been making the Ace Assembly one of the highlights of their close-up and stand-up shows for many years and now you, too can perform this classic immediately-without years of practice. A deck of cards is shown to be all face-down. You make a magical gesture and show the Ace of Spades now face-up on top of the deck! The deck is cut, squared-up and magically, the remaining three aces also turn face-up! The deck is then separated at the aces into four piles. Without any funny moves whatsoever, the four aces magically migrate, jumping into one packet!
