Overly Ambitious by Dan Harlan

There is no better way to end your ambitious card routine. After several phases, you demonstrate your magical ability to control their selected card. Finally, you end by making their card disappear from THEIR HANDS, IMMEDIATELY AFTER THEY CONFIRM THEY'RE HOLDING IT. After it disappears, it is found.. unbelievably.. ON TOP OF THE DECK.

This insane ending happens while you are FAR AWAY from the cards, they are holding the cards, and they do all of the work.

The Overly Ambitious method is brilliant and satisfying. The effect is easy to do and the vanish is so clean.
