I have had this trick in my arsenal for a long time, its like anything else, its all in the presentation

This is a heavily-gimmicked deck, but it's gimmicked in ways that are very familiar to anyone who's ever done any work with cards. Too familiar, perhaps. Hasn't everyone seen those "trick decks" where they look like one thing if you riffle it this way, but look like something else if you riffle it the other way? Laymen may not know what to call it, but plenty of them have seen them.

The biggest problem with this deck is that you're showing an effect (deck transformation) that practically BEGS the spectator to say, "Hey, let me take a look at those cards!", and naturally you have to refuse, since this deck is obviously unexaminable.

So why show this effect to anyone?
