I haven't seen any of the big magicians using black cards in a while (though I don't watch that many specials) though personally I want to get a black Arcane deck form E just because I like the way it looks and it would be cool to have a black deck. (And I don't do that many signed card tricks)
I need to start field testing my magic. That is what I intend to do. I know I have the technical skill to pull off tricks, however the all consuming fear of screwing up stops me in my tracks.
Like I said there is Bobo, but beyond that, I am a bit useless. There was a chapter in The Collect Works of Alex Elmsley called Minus 52 that dealt with non card based magic, though I don't know if you would want the whole book just for that.
