It's too bad you don't have red. Burning inquiry and wheel of Fortune would be epically good.

One of my faves for Discard decks is Anvil of Bogarden. It's forced draw and discard.

Some other cards I just found:
Gaea's Touch
Nantuko Cultivator

I want to add Manabond, but I am not sure yet.

Added a couple new cards that fit the bill:
Scorched Earth is pretty amazing. Realms Uncharted is pretty useful too. Erratic Portal makes all of the ETB creatures that much more useful. Bounce Acidic Slime, sure. How about Thragtusk, alrighty. Added Stampeding Wildebeests for the same reason. Very useful.

No that was the card I meant for versatility's sake, but forgot that you were mono-black. Woops. GIld works too, either way there are better options than Murderous Spoils. :)

If exile is what you are looking for, then Unmake should fit the bill. Or if you want more versatility, you could run Mortify.

Might also want to consider Gray Merchant of Asphodel. I drop that guy into every mono black deck I create. He is so good and can swing life totals around very quickly, especially since you will have lots of permanents out. Also, not sure I like the Murderous Spoils. It's very expensive cost wise for what it does. I would run Go for the Throat or one of the other 2-3 CMC instant kill cards instead.

Check out my mono-black devotion deck and see if you can find any gems you might have missed. :)

I could definitely see you adding in Urborg, Tomb of Yawgmoth. That will make every one of their lands a swamp, plus help you out with your cabal coffers, since it will count as a swamp too. And with the reprint in M15, the price has come down significantly.

Not too shabby. Remember that proliferate works with any counters. So a lot of the ones I posted were charge counter based. Using the contagion engine or contagion clasp to proliferate charge counters is pretty baller.

Other good ones:
Armillary Sphere
Burnished Hart
Contagion Clasp
Isochron Scpeter
Oblivion Stone
Power Conduit
Phyrexian Processor

I can definitely see a proliferate based Kurkesh deck. :)

Some cards that I can think off off the top of my head as far as artifacts go:
Lux Cannon
Contagion Engine
Titan Forge
Magistrate's Scepter
Trading Post
Mimic Vat

I'm sure there a slew of better ones, but these were ones I could think of off the top of my head.

I'll have to give that a gander. :)

Correct, it can. I was just thinking of other possible options you could run with.

Thinking of other fun cards you could use:
Panoptic Mirror would be fun, let's play a Plow Under every turn!

Thinking a little outside the box, you could add in Eternal Witnesses and Stampeding Serow/Stampeding Wildebeests. The Serow/Wildebeests will let you return the Eternal Witness back to your hand every turn which you can play to get back your Plow Under's. Or if you don't want Eternal Witness, the Serow/Wildebeests can keep on returning the Acidic Slime back to your hand. Destroy one of their lands every turn with that nice combo.

Tits cool indeed.

Thanks, that means a lot coming from you. :)

Oh, and my infinite combo deck beats this. :)

At least post useful comments to help the people that are building these decks.

No problem, thanks for looking anyways.

Well, this is an EDH build, so it needs 100 cards.

Not sure I understand the comment, but thanks. :)
