Tainted Sigil (Unless you are gaining infinite life somehow, or mass amounts of life per turn, every turn, lifegain really is kind of useless in EDH, so I would drop this and all cards that also deal in lifegain, the possible exception being Corrupt as it is also removal).
Wayfarer's Bauble (if you really need the mana acceleration after adding 2 to 3 more lands, add in Journeyer's Kite as it is reusable).
Promise of Power (you are not going to need this card. I would recommend playing an actual creature in its place...)
Out of curiousity, what are you planning to use the Hatred on? Hatred is best used with evasive generals such as Mirri, the Cursed and similar.
Drop all but the following sorcery speed removal spells (I include Rout as a sorcery speed removal spell) in order to add some more creatures or reanimation spells:

Caves of Koilos

Secluded Steppe

You should probably be running between 2 and 3 more lands of one sort or another. You don't have Nearly enough creatures. I would drop the following:
Drop all but the following sorcery speed removal spells (I include Rout as a sorcery speed removal spell) in order to add some more creatures or reanimation spells:
Chainer's Edict
Martial Coup
Vendicate
Austere Command
Akroma's Vengeance
Profane Command
Damnation
Wrath of God
Decree of Pain - tentatively...
Nevinyrral's Disk
Oblivion stone
Other than that, the list looks relatively decent...
