Another thing to consider about the metagame description:
Perhaps we should have a more qualified group work on such a description? I personally do not play enough pvp to be an authority on the manner any deeper than in a theoretical sense.
It might be appropriate, and possibly one of the best things to happen in this forum, IMO. I would LOVE to have a group of qualified PvPers and veterans of the game that cooperate on a massive work to define in practical terms "The Metagame". What works, what doesn't, why. Not only the best working decks, but also relations between them, like "Pandebonium is a very good deck because it destroys rushes. This rush here works against Pandebonium. These decks counter it. Pandebonium variations might include etc. etc." or "Unupped Gravity cannot rush because of this and this. The best you can obtain with unupped gravity is this and it is not competitive for this and this reason".
In fact, I think we could work briefly on a theoretical template then form a "Commission", finding intrested players and recruiting them temporarily for this project, to fill the Template and work towards a good definition of the Metagame. Then Deck Helpers (or somebody else, like, I don't know, a new Metagame Manager) will comment on successful new decks and update the Metagame Template accordingly.
Actually, I love this idea. 8)
