I must say that I rather like that routine that Voob referred to.
In fact I think it is the best routine in existence. I know the performer personally so may be a trifle biased.
On the website referred to there is a "for magicians only" page. This consists of an advertisement for a book on the svengali deck. It seems to be endorsed by people such as Paul Harris, Michael Close, Bill Nagler MD, Alan Wassilak, Richard Kaufmann and many, many others.
The author is a very humble person who wouldn't dream of blatant advertising so I though I would help him out. I am not sure that I approve of his previous profession though. I heard tell that he used to be a professional psychic.
