I wouldn't have compared this to the invisible deck if I were Penguin. I tried to like this but I
wasn't impressed. I bought it because I thought it had some unique gimmick or idea. It didn't, all
of this has been done before. Not necessarily as a brainwave/invisible deck but certainly in other
applications.
The benefits of having an invisible deck is that the "trick" is well hidden
and can be completely spread by the magician. This one you can't do that whatsoever. If you want an
invisible deck with a different color back that you can completely spread, just go with Dai Vernon's
Brain Wave Deck, found in Annemann's book, "Practical Mental Magic".
