Thank you for the list of resources! I did assume this "card production" was related to stacked decks, but I revently saw a performance of fhe magician letting the spectator shuffle the deck, then he still produces named cards from that shuffled deck. I guess that really blew my mind. Thank you!
Well I can't be exactly what happened in the performance you saw (though it sounds like you are talking about the Lennart Green performances), but these books do discuss how you can let the spectator shuffle and still reach the same results. Pit Hartling (page 43) teaches the Rosetta Shuffle by Lennart Green that is also used and taught on Masterfile. He (Lennart Green) also uses an additional technique which is taught in Card College. If you have that it is in the index under Green, though you will find this is not taught until volume 4.
Regardless, if you familiarize yourself with the references in the previous posts and Card College you will be able to do what you seek. Really the answer is 'learn lots of card magic' and the way to do that is Card College and for stack work, the above mentioned books (plus others by Aronson). My favorite is that Pit Hartling one (which discusses spectator shuffles), but you should probably start off with either Mnemonica or Simply Simon.
You could just get Masterfile, but you will be better off spending the $150 on books.
