I have a favorite Predicting the aces effect that takes seconds to set, and always plays very well .
Its plot is, the spectator shuffles a deck ( twice!!) you turn your back, they deal out the cards one at a time, stopping at the first ace, and without turning around you tell them what ace they have come to. Then you do the same with the other 3. I have added a new twist to the effect, where after you predict the order of 3, you chose a random card value, and predict the next card in that value. Then show an envelope containing a written prediction, which is naturaly 100 correct. And remember all of this happens in the spectators hands.
YOU NEVER TOUCH THE DECK ONCE! ( aparently) .
Where did i learn the basic version of this? Carl fulves self working card tricks. But the above twist is all mine............ HA ,HA , HAAAA....( exits, bellowing a Maniacal laugh......)
