Good stuff! I still have no clue what the format looks like these days, but I guess there's an Eldrazi thing going on? Even without any context, your opening musings on the format were a pleasant and informative read. I also enjoyed your introspection throughout the piece.
(Aside: I briefly played the Pokemon TCG competitively during college and had a very similar experience to yours at the Pokemon National Open. Even if you don't win any prizes, it's an accomplishment to end up with a winning record at a big tourney!)
