1) It's absolutely better to MTM.  The attack stat is almost double on it's own, but more importantly, so are the health and defense stats, so the MTM card will live much longer, and thus put out much more damage over the course of a fight, without even counting whatever the replacement card would be.

2) I have no idea, but I suspect it's primarily based on points, rather than deck power or ranking.  I can't prove that, though, it's just intuition.  However, to test the deck power hypothesis, I put a bunch of unlevelled R2 cards and weapons in a deck and scanned, and got a Cyclonus rank 3 just now.  So, it's either rank or points (or it counts some kind of "peak deck power" as opposed to equipped deck power).
