Dear MentalJoe: Although I am now of the school of thought that secrets need to be kept, I see nothing wrong in giving you some references for card-tossing that you may look up. Many of these are older titles that you can find at the public library, while you save for the more sensational and illusive text you seek: Professor Hoffman's Modern Magic (1887 - reprinted); T. Nelson Downs - "The Art of Magic" (1909 - currently available in an inexpensive Dover edition); Jean Hugard & Fred. Braue's "The Royal Road to Card Magic" (1949 - also readily available in reprinted forms). You can even check Tarbell Volume 4 for the flashy long distance spinner technique from Audley Walsh.
If these references point the way for your mastery of card-throwing and gratuitous exhibition of skill, you're welcome. I will remain a keeper of secrets by not revealing the deadly "Wave Slash" technique of Ogami Itto, as adapted by Mr. Jay for use with an ordinary pack of cards.
