The Vault - Neither Blind Nor Stupid by Juan Tamariz
Neither Blind Nor Stupid is easy to do and a real fooler for magicians and laypeople alike! From an almost lost mentalism principle in Anneman, this routine is a masterful and thoughtful lesson in magical structure that takes a self-working effect and turns it into a masterpiece of showmanship!
Juan Tamariz has put together a marvelous way to find two spectators' cards, and draws it out in many steps that is both mystifying and entertaining. The cards are continually mixed by the spectators, yet the magician is able to identify both selected cards. 

You will enjoy performing this!
