WOW ! This is always in my deck, always ready to amaze people. What you can do with this gimmick:
some of the most eye popping and clean color changes ever, some head scratching disapearance and
therefore some amazing transpositions or card to impossible location. Put a little thought into it
and you can come out with a place for it in your act.
The gimmick is fun to play with and
reliable. It will take some practice to be confortable with it, and it will take some getting use to
if you were to let it sit in your deck (and you will want to, just to be always ready to blow them
away). I got amazing reactions from this... Just look at the video, and let your imagination go.
This gets my highest recommandation and i'm usually hard to convince.
