Yeah, there's lots of ways you can take this.
True, but I don't think there's a method out there that's as clean and still practical as this. I think we're always trying to look for the perfect method like with any card freely named, not touching the deck at all, and it appears anywhere. If it's anything less than that, it's easy to think (as magicians) that it's not a good method. CR's is not real magic, but it creates a very powerful effect on laypeople. This is been the only thing I've been using lately and it absolutely floors people.
As for people noticing something with the deck, I've not had any problems with that so far. Psychologically, people will never notice anything unless they know exactly what to look for. Even so, I perform the card to pocket variation without any deck at all much more frequently. That's why I consider the deck as a sort of "add-on".
