RogueChomp, GA has had 10 cities. I've won 7 of them (there's another one on Saturday, too!). It's relatively easy, since nobody here can keep their decks a surprise, and the Tennessee and North/South Carolina players that came down here didn't know how to play their decks.
And I've ruined quite a few dreams of a Worlds invite for people during the course of this marathon lol
RogueChomp, I like playing more rather than less because I've never found myself having too much energy. I always seem to whiff it, actually >_< 15 Water and 4 Retrieval might be a little bit of overkill though.
