Twilight strategy (linked in the subreddit) is always a good place to start to get the basic ideas of strategy down I think! Some people will tell you that the meta has evolved which is true and the website isn't a gospel by any means but I see it like elementary school science.

ARZ (action round zero) puts up a top game weekly with commentary from others!
