ODD is a worker's dream.
* No hesitation
* No funny moves
* instant reset!
* Use your own cards!
* Only one deck is used!
Have your spectator name ANY CARD. And with NO HESITATION you show her that it's the ONLY odd backed card in the deck!
Card tricks don't get any more direct or hard-hitting.
Marcus Eddie is a brilliant creator, and ODD is a great example why.
