Ok, it's Devil's Advocate, my bad, I've been confused by the french version which is "l'avocat du diable". Won't happen again I promise. Me nice. Me hungry. Grump.
Well, Autograph isn't supposed to be a magician fooler, nobody claimed it was (except maybe Brad Christian who said he had "no idea where the second card went" at the final climax...no comment). Actually, some of the strongest stuff I perform for laymen isn't at all magician fooling material (simple colour changes, card transpos...), so it's really not a concern for me to learn such tricks.
No, I was only insisting on the fact that it was not THAT hard to understand how this trick is done once you have some basic card handling knowledge. Of course, it's always better to buy the stuff from the creator himself, he'll share with you his years of experience, what works, what doen't, the patter, the misdirection, everything. What I'm saying here is that if you don't have enough money to buy a trick, but enough knowledge to figure it out by yourself, then why wouldn't you ? I really don't see where it's not being ethical, as long as you keep it to yourself and don't expose it (or sell it, even worse).
