When I was young I had a Brainwave deck. I still have it and like it, but the Invisible Deck is one
step better. It is easy to follow the regular routine for this effect, and can be performed
close-up for one person, or pumped up and performed on stage for one hundred people, and still have
the same impact. Check out Joshua Jay's presentation on the DVD that comes with his book "Magic:
the Complete Course" and you will see what I mean.
That being said, I have two issues
with this deck. First, when I got it the gimmick was a little too much, but after I practiced with
the deck for a while it got easier. Now it seems to work just fine. Second, I was having trouble
with the "cards down" presentation, but after I saw Joshua do the "cards up" version, that is the
way I do it and it works great. It is not only easier to do, it is a more visually pleasing way to
present the effect.
Bottom line, if you do not own this deck you should get one. It
belongs in everyone's bag o' tricks.
