Well written guide. I agree with most of it though I am pondering your sideboarding strategy against golgari. Once you cut 6/8 wizards from your deck, your wizard's lightning loses much of it's fervor. It will usually just be a 3 mana lightning bolt.
My sideboarding strategy for this matchup would be to take out the wizard's lightning together with 3/4 viashino pyromancers and leave in the shock. In my current build I run 4 lava coil in the sideboard so all pyromancers go out. Note that ghitu lavarunner is still a viable 1 mana threat since your instant and sorcery count stays about the same. It's not a stellar card in the matchup but there isn't a better alternative in the current 75.
