I just happened upon Side-Swiped, started reading it, and realized, to my great surprise, that this is a fabulous effect.
It's your classic Signed Card to Impossible Location, with the added advantage that the location is in plain view and attention the entire time.
I'm doubly fascinated with it because it's rather close in effect to Darwin Ortiz's "Dream Card." There's the signature jump, first of all, and then the back-change convincer. In fact, as I work on it, I wonder if I can possibly perform my own variation on "Dream Card" (which I call "The Man with the Artistic Eyes") in the same set with Side-Swiped. It might seem like a duplication.
I'm surprised that Side-Swiped is so good, because there are so many tricks released that claim to be the best trick you could ever do, and yet turn out to be non-workers. The instruction booklet, too, is uncommonly well written, almost as well as could be hoped for.
The main drawback of this routine, of course, is that it contains a gimmick that requires constant refills. The refills are cheap, but to a worker, this is a major bother.
The other drawback is that it can't be done surrounded. Can't be done on the street, then.
I will play with this routine and see if it becomes a permanent part of my walkaround repertoire.
