some suggestions; as i played this deck before rotation A Vampire Always Pays His Debts... remove Kingpin's Pet it is utter garbage. there is no Vampire Nighthawk currently, but im sure there is a decent 3 drop in black or white right now that i cant think of....4 Debt to the Deathless is too much. consider Read the Bones and reduce the number of DttD. try to put more removal in here. you are going to need it. Hero's Downfall is great but u need some cheaper faster removal. Orzhov Guildgate needs to be Temple of Silence because scry 1 is also in a deck where u need to combo out. if you are feeling like a "johnny" fit in Sanguine Bond and Strionic Resonator ....Blood Baron of Vizkopa isn't lost in a deck like this either. or Archangel of Thune . hopefully some of these suggestions are useful. good luck.
