Stage tricks are highly visual, not a "card to top of deck" sort of things. Appearances and vanished of a live human being are amazing. If you produce a dead person... eh, reactions won't be so great, but a living human being always gets 'em.
Many illusion designs are available in Mark Wilson's Complete Course in Magic, with appearances and vanishes, and even a levitation of a human being! Andrew Mayne, www.weirdthings.com
, has many great illusion designs for sale. They're amazing.
Personally, some neat stage effects (the first one can also be done close-up) is Bisection. Just attach a curtain to a hula-hoop, and do the effect. Half a body vanishes. Very cool! Re-appear, kick the curtain and gimmick to the side, and you're left clean.
Another one I like would, yeah... have to be a Zombie Ball routine. A good Zombie Ball routine, that is.
Hope it helps.
