Nice deck! It may need some card draw options, though. Maybe Staff of Nin, Reforge the Soul, Wheel of Fate, and/or Knollspine Dragon (I'm sure I am missing a few). Also for the Sunforger package, try Reito Lantern and Mistveil Plains to help reuse your instants.

Necropotence might help with card draw. Also, Living Death can completely flip a game in your favor mid to late game.
