Can you Exsanguinate for 37 off of the top assuming it is the top card when the Citadel hits?
I'm assuming X spells won't really work, as they can only be cast as their converted mana cost, which would be BB and X would be zero for Exsanguinate. I assume that's how it works, otherwise reminds me of.. Channel + Fireball hehe
You are assuming wrong. Bolas's citadel simply lets you cast spells form the top of your library, it does not give the spells an alternative cost to its mana cost like omniscience etc. does. It simply change what you pay for the spell when the spell is "locked in".
I'm not sure what you mean by the spells only being able to be cast as their converted mana cost. The mana cost of exsanguinate changes and while on the stack the mana cost is the "base cost" plus the value for x.
So basically yes, yuo can cast exsanguinate for a lot.
This official Magic Rules person says that X=0 for X spells..
Blood Vassal, Basal Sliver means you lose 3 life, so you'd still need a sacrifice outlet and a one drop to sustain the life loss?
You'd be losing just as much life as opponents, so you'd need a higher life total.

You could combine mana producers like Priest of Gix, Pitiless Plunderer with sacrifice outlets, to keep looping with Haunted Crossroads.
Any aristocrat creature will let you do it indefinitely, Zulaport Cutthroat, Blood Artist, Falkenrath Noble, Bontu's Monument, but I think you'd need a one drop creature as well to sacrifice so the life loss balances out.
Blood Pet would work without needing a sacrifice outlet with an aristocrat and Haunted Crossroads.

You'd be losing just as much life as opponents, so you'd need a higher life total.
Pawn of Ulamog would need a filter outlet like Bog Initiate, Initiates of the Ebon Hand for a mana producer with Haunted Crossroads.

Doomsday as well.
Scroll Rack can be combined with tutors. So the ones that can get more than one card are going to be game winning..Demonic Collusion, Diabolic Revelation, Increasing Ambition, Behold the Beyond.
Congregation at Dawn can set up a combo creature win.

You can go infinite with Sensei's Divining Top and Aetherflux Reservoir.
What other cards are going to help with your life?
Some off the top of my head are white creatures in Resolute Archangel and Exquisite Archangel.
If you were making a mono-black deck, what would some good cards be?
