ODD allows you to show that your spectator freely selected the only odd-backed card in the deck. It
is well thought-out, the choice really IS free, and the display move completely sailed past me, the
two times I watched the promo video. This was the main reason I bought it.
It requires a
little bit of construction, which shouldn't be a problem. And the display move is so well
thought-out that--if you do it properly--your spectators will be convinced they've seen the entire
deck. However, the deck cannot be examined at any time. And I don't know how many buyers will be
able to use this deck for another trick. I think this limits its use.
The way it's
taught requires the use of a clip. You should be able to figure out how to do it without one. And
maybe doing it without the clip you could ditch the ODD and come out with a regular deck, should
your spectators be hungry for more card magic.
