Big black sac

Please comment and tell me any improvements you think would help.
This is sort of a budget deck.... I just tried to keep the price down.

The initial idea would be exploiting skull clamp and bloodghast or nether traitor. sylvok lifestaff can be equipped before skullclamp for bonus life. So the combo would go as follows:
1. equip lifestaff to bloodghast.
2. equip skullclamp to bloodghast.
3. bloodghast dies.
4. draw 2 cards gain 3 life.
5. play a land card.
6. bring bloodghast back.
repeat steps 1-4

hopefully later in the game you will have pawn of ulamog on the field which will yield a 0/1 token for every sac of bloodghast these tokens can also be sacced to skullclamp and lifestaff.

So for a total of 8 mana you can draw 8 cards and gain 12 life.
attrition and grave pact mostly exploit the numerous sacs on your side of the field.
forcing the enemy to clear their board very quickly.

your win conditions here are demon of catastrophes, skirsdag high priest and flesh carver. grisselbrand could probably find a spot in here i just haven't worked that out.
phylactery lich is an early game body that is difficult for opponents to deal with. this is mostly there to slow the opponent while you complete you combo and draw into your win condition. you will place his counter on lifestaff or skullclamp.
tragic slip is usually useless but if everything doesn't work out for you it will be a life saver.

Some cards that will benefit the deck but raise the price are: nether traitor and phyrexian obliterator. also gain grisselbrand...
