You have a lot of creatures that benefit when creatures die but not many ways to kill your own creatures. Viscera Seer and Cartel Aristocrat are awesome in that. Lingering Souls gives you a lot of sacrifice fodder. Bontu the Glorified can be a good finisher.I would replace clame/fame with Return to the Ranks it a bot more flexible.

I wouldnt play Death Shadow, there are better ways to let you creatures die. You also dont need Torment of Hailfire and Pawn ofUlamog. They are to slow and not very good on their own.

I wouldnt play Bone Splinter Fatal Push, Path to Exile and Tragic Slip are way better.

Would Death's Shadow not be better as Bile Urchin?

Why?I dont think so to be honest, but I wouldnt play neither of them.

LeaPlath honestly Death Cultist is probably a more effective (and cheaper) card than Death's Shadow but im also trying to use a commonly used card in an uncommonly used way lol.

LeaPlath meant Bile Urchin not Death Cultist

Well Death Cultist is a strictly better Bile Urchin

Did you consider using Proclamation of Rebirth and Vexing Devil in the build? Could be fun :)

I LOVE IT
