Made a few changes and started trying to make the sideboard actually useful.
Sideboard: Added 3x Cultivate. Against decks running countermagic, these will go in for Harrow, because I simply can't afford to lose a land to Harrow then have it countered.
Added 3x Greater Auramancy. Against enchantment removal, these'll go in and Asceticism will go out. I rely really heavily on enchantments, and REALLY don't want them dead.
