I used to play a seemingly random Steel Hellkite earlier but the 4th Exploration Map replaced it in order to get the big mana flowing as soon as possible. Glimmerposts and needles were doing most of the work today. Sideboard makes the TES matchup feel not terrible at all.
I wouldn't change a thing since this is working like charm in my meta. I have some idea on how to tweak the sideboard, though.
