Hey Rneogy, Randomly, I'm an attorney, so I suppose I can chime in on the copyright issue. You can't actually copyright a card move. Even if you write up a really long, complex description of it in a book. (Though your wording and the book COULD be copyrighted). BUT, that said, t11 still has the right to reject a trick for using an unoriginal move. And it makes sense that they'd want to. (People come to The Wire to discover new, original magic). So in the end, I guess the question would be: How much new stuff is your trick bringing to the table? If the already-done move is just a small part of it, I'm sure JB and everybody would be happy to see the submission.
(To summarize: the issue of whether you can published on The Wire is separate from the issue of whether you can publish the trick while avoiding a charge of copyright infringement.)
