Isn't that what RikAllen said? In the last line of his post he states that the effect is nothing without seeing how he reacts with the spectator. I'm taking this to mean, the effects is weak if you don't present it properly.
While I did say a presentation would make the effect, I think the structure could use some work. Overall it's not bad (after re-watching) there is just one point that makes no sense at all to me. If there are no switches or palming then the card that was touched doesn't need to go back into the deck. Overall the effect could be quite strong, in the right hands, and I actually kind of liked Craig's laugh, came off very mad scientist, and the exercise (Rick Maue's take an effect one) is great advice so I'm actually happy if there was a misconception-I got to learn something to try out in the future.
And now I also know I'm not alone on the Center tear (as it is used most often). Write something down! wait...let me tear it up and burn it...In the right hands, for the right people...I don't know I always thought it was see-through too, but it's one of those moments where your attitude towards the billet will determine the spectators attitude (casual and indifferent = indifference from everyone.)
At the end of the day if your spectator says 'I wrote something down...and then he told me what it was!' as opposed to "I was thinking of ______ and he freaking read my mind!' then you're doing something wrong in the first place. How did you do that? vs. How did you
know that? Pretty sure I stole that directly from D ICE R or Prae (or both) but it's a great point, and the difference between mentalism and mental magic (or magic in general).
As for the card trick and a prediction, I think the best prediction with a deck of cards would be a spectator shuffles and you pull out a second deck and then show they match card for card. Not quite mentalism, but a strong effect. I'll let the mechanics work out the handling, ringing in a cooler shouldn't be too difficult to figure out.
and finally @Malik, you've got a decent effect, it could be made stronger with a better build up and presentation. Try performing it for a few people and see how the reactions go, and that should tell you more than any magician on a forum can. If they react the way you plan for them to, then it's a good effect, if it's not what you're going for-attempt to re-work it or decide to scrap it.
This is why I never ask about my own effects, my spectators tell me all I need to know about their strength and whether or not they need a little work or if I need to start over completely.
