MTG Salvation

Hello everyone! This is my first post on MTGSalvation but I have lurked these forums for awhile. This was my first EDH deck and it is still my favorite, but I think it needs some work. I have made my own modifications over the years but now I need others opinions. Korlash, despite not being the best creature, was my first choice for commander. I've considered switching to others (Skittles, Drana, etc.) but could never part with having Korlash at the helm. I also will not change the deck from Monoblack. The main theme through the deck is counting Swamps to coincide with Korlash's ability. I have not included every card with this theme, but I think the good ones are in here. The deck goes big on land and big on mana. I want some suggestions for modifications to this deck to make it better for general multiplayer games. However, I don't want it to be crippled in 1v1. I do not have a playgroup right now so keep it as general as possible. It can easily win with through Voltron, but I don't that to be my go to every game, as the fun of EDH is having a different experience each game. Before we start, I want to address a few things. (The numbers in the decklist are CMC, except Swamps, which I have 24 of.)

• I do not like tutors. The only tutors I run in here find me lands and I will not run any traditional tutors. I know that is what black does very well and is a great benefit to black decks, but tutors are not fun to me, so do not suggest them unless they are land tutors.
• In that same vein, I also don't like using my graveyard. I'm the oddest black player ever, but I like the graveyard only in certain context as a resource. I do not want this deck to use my graveyard much. Beacon of Unrest is there for the fact it gets also artifacts,it recurs, and can use my opponent's graveyard. Ink-Eyes is a pet card and not a problem because I do like using my opponent's graveyard.
• Listing the cards here made me realize I might have a bit too much removal. I never really considered proper ratios for spells, but as you can see in my list I have a lot of spot removal, sacrifice effects, and mass removal. Trimming those down to proper ratios and other suggestions are very welcomed.
• I had tried in the past to make a sub-theme of Grave Pact like spells, small recursive creatures, and abusing death triggers in general, but it just muddled what I really wanted to do with this deck. I'm not sure if that removal suite would be able to be compacted and fit into the deck by taking out some of the current removal, so I need opinions on that as well.
• I also think that my equipment set could use some work, though as I said I do not want to always go to Voltron.
• I'm not sure if my land count is right. I realize I have a lot of nonbasics for Korlash, but it only becomes a problem if I cannot get Urborg out or if it gets destroyed.

I suggest adding things that give him infect so that you can end games even earlier when attacking with Korlash.
