I saw Choice of Damnations and couldn't stop laughing! it's not because it's a bad card, it's because I generally play against goblin decks.
Lets see, sacrifice my army or lose half my life XD. Oh and cool deck.

It's a nice card but I'm trying to stay Mono black.

Ya actually you're right, I only have one but it's such a good card. I don't know if I can bring myself to replace him.

From the look of your deck it seems like you play to win. However, unless your going to be strictly a milling deck you should lose the milling cards. For example a grisly spectacle could be replaced with murder.
However, if you did per say go with a milling theme and had a bit of cash around, I would suggest Jace's Phantasm, Precinct Six, and Consuming Abberation

This is a really cool deck and wow that's a lot of views
Just a thought but since you should be having extra life perhaps you should include some sign in bloods
Not only would it condense your strategy but you would get cards faster than your opponent
The only problem is it's two B mana. However, I think you could pull it off.

This deck is Amazing

Finally someone who understands!

I think a Duty Bound Dead may prove useful here. Also ya you need more creatures for two reasons. One, to stay alive when your opponent wipes the board with their own Mutilate. Two, to further take advantage of exalted. Other than that looks great.

I like the idea of mark of the vampire in an exalted deck.

Yes I agree, though it may prove annoying for something like Tormented Soul.

I hate you.

Here are some creatures you might want to use
Angelic Skirmisher
Daggerdrome Imp

You mat also like Gift of Orzhova and Moment of Heroism

A good planeswalker would be Sorin, Lord of Innistrad

I would take out wall of glare and use some Basilica Guards for extort

It's a really good idea I think. What I assume is your strategy is to steal your opponents life in a way that they can't do anything about. Then when they attack you, you have extra health so you don't even really need to defend. You keep repeating the process until they run out of life to steal. When they leave themselves defenseless to attack you, you take out large chunks of their health with Geralf's Messenger. I think that you may want a few more cards with extort. They're usually black/ white and are even standard legal if you care for it. They would be a nice addition to this deck. You can find a lot of those creatures in Gatecrash btw.

Now I wish more black cards had double strike XD. I would take out the Angelic Benediction and add a Cathedral of War. Not only will you still get the Exalted bonus, you'll also have more manna to cast things like Asceticism, True Conviction, and Overrun.

Cool deck. It very unique and it has a clever strategy.

What!? Why isn't there a Jace's Phantasm?

If anyone has a suggestion, I would love to hear it. Just don't suggest more Tormented Souls because they don't work well together in an exalted deck.
