Gauntlet of Power and Magus of the Coffers are very useful ramp cards for mono-black EDH decks.

You might want to check out my EDH MBC deck deck:korlash-mbc-the-edh-way. It's been pretty successful in all the games I've played it.

Geth, Lord of the Vault and Ink-Eyes, Servant of Oni are good ways to rip cards from your opponents' graveyards.

Hymn to Tourach seems very underwhelming in EDH.

Epoch did you delete that deck or set it to private at one point? It's not linking to anything.

I'd suggest some instant spot removal, sometimes board wipes and permanent based removal is too slow or not quite online when an aggressive tron deck gets their beats going (for example Kaalia of the Vast can drop 1 of two angels that can hose this deck, Iona, Shield of Emeria and Avacyn, Angel of Hope ).

I deleted it a while ago. I took the deck apart to fund the construction of Dominus - Dreamcrusher Edition.

Which spot removal do you recommend? I had a lot of spot removal at one point it felt pretty useless since I could never really have board control, a single Murder or card:Geth's Verdict seems almost like a lose of card advantage. I really like creature based removal like Shriekmaw because I can recur as functional spot removal and because they serve as chump blocks. In addition they also comeback if I cast Living Death .

You shouldn't pack the deck with a bunch of spot removal, but a Murder would fit well. Your main focus should be board wipes since they give you better return on investment.

Xiahou Dun could be great in this deck if you are willing to spend $20 on a single.

maybe switch Liliana's out? The dark realms one is just awesome in mono black.

also since you are running cabal and yawgmoth it is so easy to win with mana sink cards like Profane Command and Exsanguinate

Depending on how much a jerk you want to be you could run Contamination and if you have a creature with persist with Mikaeus out it will just come back out and makes it easy to have a creature to sac, or run Breeding Pit and it makes it really hard for your opponents to play things unless they run black as well.

play Phyrexian Obliterator

and you may want to have a look at my mono-black EDH Horrors of the Last Days

Just to be clear I want to be a jerk, a massive jerk. (I just don't want to break the bank or the rules.) I am pretty tired of the infinite combos or people hating on the MBC deck because they assume that I am playing unfair stuff.

Crucible of Worlds and Vedalken Orrery may be useful as well since I noticed that some of your lands have sac effects. Playing things at instant speed is sorta good too. And Black Market is good if a lot of things are dying.
