stop posting. You haven't listened to a single damn thing. This is the extent of my procrastination
Firstly:
-A camera man doesn't count as a spectator. We can't see how well they're being misdirected, or their reaction, or your interaction with them.
Write a script to the trick. Seriously. Actually, i'm going to transcribe your patter right now, so you can realise how bad it is.
"We'll start by giving the deck a cut, and riffle shuffle them together [stop narrating what you're doing]. Now sir, could you please select a card? Any card will do [semi-acceptable, as long as you really talk this way]. Please remember your card [should be asked after they wish to change their mind]. Would you like to change your selection? [should be asked before asking them to remember the card] Now say stop anywhere [not necessary, just get them to place it back wherever]. Please place your card there. Give the deck a couple of cuts, and riffle shuffle... the deck together [STOP. NARRATING.] . So your card is still somewhere here in the deck correct? [What is the point of this question? It's like you're insulting the audience's intelligence]. Is this your card? Your sure that the 4 of spades is not your card? Well, we're going to pick up the 4, and if the 4's not your card, then the 8 of club has to be your card? It's not? See, this is a very special deck, your card will reveal itself to me. Just a wave of my hand over the top of the deck. The only card reversed in the entire deck... is this card... would you be surprised if this card was your card?"
Ok. This is a sucker trick. It means that something went "wrong". Which means that if this trick had gone correctly, it would have ended with you turning the deck over to their selection. Which in that case, it would have been a rubbish trick. Anyway, continuing.
This is a SUCKER trick. It means that something went WRONG. Ever seen a magician really screw up a card trick? What happens to their face, their voice, their body language? Emulate that. If you can't, don't do sucker tricks. Ever seen a magician try a really bad recovery after screwing up a card trick? That's what you should be emulating with the second screw up. If you can't, don't do sucker tricks.
The ending is so out of left field. There is no logical premise why you'd reveal the card face up. At least if you had structured patter, you could make the ending make sense, something like "well, I was never really good at cutting to cards anyway, so I make them easier to find". If you had established at the beginning that it is a "magic deck" and can make it congruent with your style, it would have been better.
Can't believe that I don't want to study this badly.
