I like the invisible deck and the burnt card the most.
Svengali decks are cool.. I had one bartender place the force card in the register's till and performed it for the other bartender and a few on-lookers. I did a standard Svengali routine, then at the end I "threw" a card (mimed the motion, really) at the register, and when he opened it, there was the card. Great response.
Strippers are fun.. they can make other tricks easier.. I've used them for 2CM a few times. The action seems extremely fair, because you can spring or dribble the cards and quickly pull off the 'top' card. (I know, I know.. I should use the lift, but it's not perfect yet. I'm working on it)
