Hell's Caretaker , Corpse Hauler , and Doomed Necromancer give you recursion plus a sac outlet (which are both very valuable for a sacrifice deck), Attrition and Bone Splinters give you targeted removal plus a sac outlet, Diabolic Intent gives you tutoring plus a sac outlet, Gate to Phyrexia gives you serious artifact hate plus a sac outlet, Glen Elendra Archmage gives you a counterspell plus sac outlet, and Mind Slash gives you hand control plus a sac outlet. With a deck like this, you ALWAYS want an opportunity to chew up creatures.

Mind Slash is a really interesting prospect, seeing as I dont really have any other form of discard in the deck... But, seeing as they reveal and I pick a card I can see it being a viable thing.

I ran Gate to Phyrexia for a little while, but it is just way to slow

Ashnod's altar + Nim deathmantle + Grave titan + Diregraf captain/blood artist= end gamer, just a little tip hehe

I'd suggest Inexorable Tide , but thraximundar seems to be the only one I can find who benefits from the proliferating.

okay, never mind, you have 2 of my favorite cards, Lightning Reaver + Necropolis Regent

@iceonfire Ashnod's Altar + Nim Deathmantle + Grave Titan + Diregraf Captain or Blood Artist

Have you tried Altar of Dementia?

I'd recommend Unholy Grotto in this deck considering the zombie creatures you have here.

You should add Insurrection I know it is high costed but it is worth it to swing out with all your opponents things then sac outlet them so they get nothing back.

Have you thought about Liliana of the Veil? Seems like it would be fantastic in here.

Also, Nicol Bolas, Planeswalker Would also work well.

I kind of want to run this deck, but a lot of the cards are out of my budget range, do you have any suggestions what I could cut?

Cool deck, but with 40 out of 64 spells being 4-drops or higher, isn't this waaay too slow, even for commander?
