Forgive me if it's terrible, but I am bad at this game. Essentially I'm going by what feels good from Theros, and using it over stuff that's rotating out. If it's any decent, I'll probably wind up making it my IRL deck, given I have some of the frame for it.

So, any advice? (Apologies if the build is crap)

Is it really necessary to splash Red just for Dreadbore? Hm...

Needs more Rakdos's Return if you're in Red.

And Lifebane Zombie, really. It's not worth it without the serious threat it is along with the fact that it's always a 2-for-1 or at least a free peak.

Way too many Doom Blades here.

Hythonia just seems pretty bad without playing Crypt Ghast for acceleration but that's also an obvious non-bo.

Thoughtseize seriously wants to be here.

I also personally find Abhorrent Overlord to just be an insane finisher, obviously not necessarily applicable if your curve becomes too high, but I really like him in Mono Black without the red splash.

Oh I derped on the Rakdos Return.

I thought I already had it in here O.o

So:

-2 Doomblade
-1 Hythonia
-2 Desecration Demon
-1 Swamp

+2 Lifebane Zombie
+2 Rakdos Returns 
+2 Thoughtseize 

That sound decent enough?

I think you want the Demons more than the Plate Mails.

Also think you definitely need 25 land if you're Corrupting and Rakdos's Returning.

So instead:

-4 Plate Mail
-2 Doom Blade
-1 Hythonia

+2 Rakdos Returns
+3 Lifebane Zombie
+2 Thoughtseize.

Seems fine.

Not sure if you want to keep Ratchet Bomb over another Lifebane Zombie though. Lifebane Zombie is just seriously insanely good.

I will also second the Overlord. He just looks like an awesome finisher.

I'll test about the Ratchet Bomb.

I want to do this at a sort of budget without selling to many of my playables/worthwhile stuff.

I've got a Revalation set aside to cover for most of it (Namely Returns, and now the Zombies and Demons), Blood Crypts are a nightmare to find around my area as it stands, and the rest of it will be annoying to find as well.

If it tests well enough I will run this, if not I may just stop the red splash and just run it as mono black, since I can probably find more stuff for that easily. 

I'm gonna put up a Mono MBC in the morning for you guys to look over, and see about that instead.
