I too, was fortunate enough to have Ryan and AmberLynn perform this trick for me. It is a stunner!
Being familiar with codes, I was also looking for some type of signal...NONE!
Deceptively
Easy! Probably the easiest "setup" I have ever had to learn...and can be learned in a matter of
minutes.
Deceptively Strong! Having seen it performed live...it slays magicians and laymen
alike. Even with a borrowed deck! The fact that it can be repeated over and over leaves 'em
stymied. (Although, once is quite enough to stupefy anyone.)
Deceptively Deceptive! Ryan's
idea of never having to even see the selected card makes it an impossibility.
All in all,
this is an extremely practical and performance worthy effect that is definitely going in my arsenal.
