This appears to have been a straight vampire deck with the goal of building up to Sorin, Kalitas, or Ob Nixilis. It is not very creative, but probably would be effective. The 14/19/4/0/1/1/1 curve is very cheap, coming in at just 2.05 average despite the three big guys. While there is every reason to want Kalitas or Ob Nixilis early, given the creatures along the way and their costs, I am not certain I needed a full contingent of Dark Rituals.
