Yeah, I sort of knew those moves. I don't have CC2, but it's on my Wish list. I do use the cull (I thought it was my move) I would not be able to apply the cull to that You Do As I Do effect (of my creation) There's quite an elaborate set-up that involves removing a card from one deck, putting a double-backer on, holding a break, and a few other things.
I use the top change, but not properly. There is a top change taught on David Stone's Window DVD that I've been working on for the last few days though.
