I normally do a biddle-type effect, or some sort of transposition into their hand. But Jroberts gave me an idea. I'm working on a spellbound effect with a fast change from a half dollar to a bronze coin. Then you slow down the change. Its quite visual. But anyways, you lead into a vanish, of then coin, then a re-production, then a coin-to-deck transposition. Then from there I'd go into some hard-hitting visual card material. I like it. It has a lot of aspects in it: Color changes, productions, vanishes, etc.
