I'm not completely set on any of the cards above, but it gives you an idea.
So I was thinking of ways to build this deck, and besides the expected (sac everything for Exsanguinate via Ashnod's Altar et al), I'm short of idea's on other directions to take the deck.
I want the deck to be flexible.
What other win-con's could work here?
You can also try a more aggressive route with cards like Carrion Feeder and/or Nantuko Husk. GibbonMonk makes excellent suggestions with creatures that penalize your opponents everytime your creatures die. Most of these cards are Zombies so they would work really well with your Gravecrawler.
Mortarpod is another card I would recommend as a possible recurring source of damage and as an additional sacrifice outlet.
Here's a rough draft of a Zombie/Sacrifice deck I would recommend:
Your deck can be really aggressive at times and can also play out a grinding game by using Mortarpod or any of the Sac Outlets together with your Blood Artists. Or, you can amass a handful of zombies in play and cycle Gempalm Polluter for massive life loss.
So I wanna build a silly black deck that sac's it's creatures to win, and generally plays from the grave.
(I'm not looking to build dredge)
Cards I have;
Bloodghast, Gravecrawler, Nether Shadow, Reassembling Skeleton
Vengeful Pharaoh, 1 Filth, 1 Ashen Ghoul.
Grave Pact, 2 Dictate of Erebos, 1 No Mercy.
Evolving Wilds/Terramorphic Expanse (for ghast)
Lashwrithe, Buried Alive

Spawning Pit is one of the best budget sac engines.
In this deck you could surely run Death Pit Offering for boost and as a sac engine. Or you could simply slam in anoying equipment like Loxodon Warhammer and Quietus Spike.

Devouring Strossus, just one, for style points?
Attrition, sometimes it just has to be targeted.
Harvester of Souls, adding insult to injury.
Beacon of Unrest, for the dead that are just too juicy to let rot.
My meta: 3 or 4 player free for all, anything goes but boring games or broken decks cause a vote to end that game.
