Based on the old Potty Prediction and Zeudo Zycho effects, here is a new version by Ton Onosaka, guaranteed to bring the laughs.

A giant ACE prediction is shown to the audience and placed into a folder so that the spectator cannot see it. Now he/she is to select a card from an oversized pack. (They are shown to the audience to be all Aces.) Here is where the fun continues. The selected card turns out to be a QUEEN. Open the folder that holds the ACE - as you remove it, the card visibly changes to QUEEN!

Very visual and colorful as are all the Onosaka effects!
