I'd cut torment. Cool card but much better in a big mana black deck

I can understand that. The idea was to sack a bunch of tokens to Ashnod's Altar for big X values, but I guess I already have that with Exsanguinate.

Any thoughts on what to put in? My gut says Monastery Mentor, but I'm not sure as it's not a vampire and I don't really have a focus on non-creature spells.

Sanguine bond is in your maybe pile. You should throw that in for the incidental combo. Also I've been liking the extort trigger from blind obedience and tithe drinker. Also keep in mind for effective tribal stuff you want a solid 30-35 creatures of that tribe for this kind of creature based thing

Stalking Vengeance may be an effect you want, although it is quite costly. Goblin Sharpshooter also seems like it could be great.

This is an interesting take on Edgar Markov; points for creativity! Oathsworn Vampire and Forerunner of the Legion seem like they'd be good fits for the aristocrat theme.

Cool deck! What's your oppinion on Vampiric Rites and Goblin Bombardment?

I think both of those would probably fit very well in the deck!
