Deadly are they? Yes! The '4 Deadly Aces' trick astonishes all!  This trick starts out with some strange shuffling methods, and then right into the action.  The magician or spectator then lays the cards in four piles, and starts into another odd shuffle.  3 down and 3 around is what it's called.  And in the end it is the deadly 4-some that appears on the top of each pile.  Great trick for anyone, easy to learn!
