R. Paul Wilson performed at the Castle not too long ago, and I was fortunate enough to see him use his Predator Wallet in a live setting. Honestly, I've never been fooled so badly. In fact, I bought the wallet the day after I saw the performance, and I'm still puzzling over it while I wait for it to arrive in the mail.
In short, he removes three dollars from an otherwise empty wallet. Someone thinks of any card they want-- it's obviously a free choice. The bills which were in plain view throughout the entire performance are turned over one by one to reveal the card's identity. For instance, on one bill is scribbled 'EIGHT'; another says 'OF'; and the last bill says 'DIAMONDS'.
Nate Staniforth's Lottery Prediction is one of the cleanest Confabulation effects I've ever seen as well. To this day, I've no idea how it was accomplished.
