Generation Extreme by Brian Tudor is EXTREMELY DIFFICULT, will take years to learn, but can be useful.
Generation Extreme is more regarding card magic than artifice. However, he did produce a card cheating DVD "Card Sharp", but it's a very poorly produced DVD. I don't recommend any of Brian's work for card cheating, not even by a long shot. Darwin Ortiz, Ed Marlo, Steve Forte, Richard Turner, Jason England, Erdnase, Martin Nash, Michael Skinner, Gene Maze; these are guys that have good pieces of work on card cheating.
