DELPHI

An incredible mentalism routine where the spectator gets the prediction before the routine starts! Welcome to DELPHI!
The performer gives the spectator an envelope to keep. Then the spectator choose four spot cards from a deck and adds them together, after which he counts down to that number in a deck of cards. And the prediction in the envelope shows you knew the arrived-at card before the effect began! And all this without palming or switching and nearly self-working!
