Need:
Anowon, the Ruin Sage
New Blood - Too thematic not to play
$$$ Twilight Prophet
Bishop of Rebirth
Kheru Mind-Eater
Bloodcrazed Paladin
$ Kalastria Highborn
$$ Metallic Mimic
Falkenrath Gorger - Aggressive, and protection against wheels
$ Gatekeeper of Malakir
$ Kindred Charge
Viscera Seer - Should have extra, but can't find

When replacing Kambal:
Blind Obedience
Drana's Emissary, Cliffhaven Vampire, Epicure of Blood, Defiant Bloodlord?
Well of Lost Dreams?

Consider:
** Mavren Fein - Max one per turn? Probably not worth it
* Blade of the Bloodchief - Pretty good with a lot of tokens, but it's just a few +1/1 counters if I don't do the sacrifice thing
Vona, Butcher of Magan
Obelisk of Urd - With lots of tokens, convoking this out should be easy
Butcher of Malakir - Is it worth it if I don't sac my own things?
Skullclamp - Should play this, but don't think I have enough copies
Drana, Kalastria Bloodchief - Quite expensive to use
Sangromancer
Elenda, the Dusk Rose - Amazing, but probably more important in Teysa
Vampire Hexmage
Pawn of Ulamog, Voldaren Pariah - If playing more sacrifice stuff
Asylum Visitor
Fell the Mighty
Dreadbore
Terminate
Chaos Warp
Return to Dust
Black Market
Urza's Incubator
Last One Standing

Consider (don't have):
Vampire Nocturnus
Licia, Sanguine Tribune
Olivia, Mobilized For War
Blood Tribute

---------

Considered cuts:
Arguel's Blood Fast
Outpost Siege
* Sorin Markov - Too mean, and despite being Sorin, not very vampire-related
Bloodghast, Vampire Cutthroat, Vicious Conquistador - Not very impressive, but at least they come with a buddy

---------

Cuts:
Pawn of Ulamog - More important in Deathharmonicon I think
Mathas, Fiend Seeker - I don't want to give away life or cards
Falkenrath Noble - Used in Teysa
Viscera Seer - Can't find
Skymarcher Aspirant - Not very impressive, and it's not that likely that I will have untapped white on turn 1
Malakir Cullblade - Not very impressive
Bloodchief Ascension - I'm not really putting a lot of cards in their graveyards, and at that point, this isn't fast or reliable enough
Vish Kal - Expensive and not so synergistic
