Fantastic write up, you really hit on a lot of good points that I don't see discussed a lot with this game. Specifically, the idea of the "flavor of the month" decks. Sometimes, it takes only one good tournament or top ranked deck for people to chase after certain cards.

Another thing I'd keep in mind is the evolution system that was recently announced. It's possible that there may be key cards needed (possibly even high shine levels) that will be needed to make the new trinkets.
