Two effects for the price of one!
Combine an ESP prediction trick with a slick card effect- and you have a miracle!
THE ESP PREDICTION EFFECT:
You select an ESP symbol from your set of cards, and you have your spectator choose one from his set.
The symbols MATCH!
BUT WAIT- that's not all!
THE CARD CHANGE EFFECT:
Now you change ALL of the cards to the selected ESP symbol!
Clean and easy to do with a minimum of practice!
