Started working on a deck using Olivia Voldaren last week, this is what I came up with. Play tested it with some friends this past weekend and I really think the deck curves out too high. Any suggestions on what to replace would be greatly appreciated. Please give reasoning with each choice and I will take it into account. I have been considering making room for Deathbringer Thoctar, Pestilence, Mutilate, and Elemental Mastery. I understand the benefits of the first 3, but am wandering if anyone else has tested Elemental Mastery to create tokens to sac for a pseudo-board wipe every turn with grave pact or Butcher in play. I want to keep this deck fun to play against, and I don't want to go straight vampire tribal though the current version does have a tribal sub-theme due to how well the cards work together.
These cards aren't bad, but they're also not furthering the goals of your deck.
If you want to keep a lot of these higher cost card I would suggest adding around 5 more lands and a lot more ramp, cards like Rakdos Signet, Mind Stone, etc.

Two simple changes I would make:
Falkenrath Noble > Blood Artist
Slum Reaper > Fleshbag Marauder
You're overloaded with threats as well, here are some cards I would personally cut:
Blightsteel Colossus
Sepulchral Primordial
Grave Titan
Flameblast Dragon
Sorin Markov
Drana, Kalastria Bloodchief
Whip of Erebos
