Ah, Shade. An underrated movie.
Depends on which part you mean. The ace production is nifty but I don't know if it has a name.
Otherwise it's basic gambling demonstrations. Card controls, false shuffles, false dealing.
I can't remember if the specific multi card control they're mimicking (I doubt he actually did it) is in Erdnase, but I do know the false shuffles and bottom dealing are. They are all probably covered in Gambling Sleight of Hand by Steve Forte if you want to make the serious investment. I have it, but I haven't read it yet.
