If you're looking to speed up the deck, I would suggest Rakdos Signet. It's kinda meh, but it's cheap and accelerates mana easily.

That is true. I'll try testing it out and see how it works.

Talisman of Indulgence is a pretty decent mana rock. Smokestack is also a really good slug card.

Mogis, God of Slaughter for the PAIN!!! +1

You have incendiary Command in the deck twice. once under control and once under draw

@BossColten: Yeah, it does both, but there is only one copy of the card in the deck if you look under type.

Price of Glory would be good in here.

A good card-drawing one would be Seizan, Perverter of Truth.

I like Seizan but he has a couple problems. It's effect triggers during the upkeep, which means I don't benefit until my next turn. The other is that it is a creature, which means it's very likely it won't be there during my next turn. Thanks for the suggestion, though.

What do you think about Mogis, God of Slaughter

I pulled one from a Fat Pack and tried it out for about a month and I found it to be underwhelming. The biggest problem is the low impact it has. 2 damage a turn isn't much, and I found I was actually helping some reanimator decks by giving them a free sac outlet. The other is the cost. 4 mana may not seem like much, but to put it into perspective, Spellshock costs 3 and deals anywhere from 2-10 damage a turn. Ankh of Mishra costs 2 and deals 2-4 damage a turn, maybe more if they're ramping. For the same cost Erebos, God of the Dead permanently* prevents them from gaining life and lets me draw cards with spare mana. I often have the devotion that would be needed to activate Mogis, and hitting for 7 is nice, but I also run cards that punish players (including myself) for having creatures.

TL;DR: It doesn't have a big enough impact to warrant inclusion

Have you considered Bonfire of the Damned?

I have not. My problem with it is that I can't manipulate my library to benefit from the miracle cost, so I'll be paying a majority of the time. I can also really only generate a sufficient amount of mana when I use Yawgmoth's Will with some ritual cards, and if I'm doing that I'd rather play my whole graveyard than Bonfire of the Damned. Thanks for the suggestion, though.

What about Death Pits of Rath and Furnace of Rath?

In terms of a Silent Arbiter Replacement, maybe Crawlspace?

I'm going to try out Crawlspace. As for Death Pits of Rath and Furnace of Rath, the Death Pits is a little slow and requires Kaervek to work, while the Furnace of Rath doubles the damage I do to myself, as well. I know, "no pain, no gain", but I kill myself enough that I probably shouldn't run it lol.

rakdos signet

kind of meh

Ha. Signets are amazing.

If you wanna replace Killing Wave, I suggest you to try Toxic Deluge.

What do you think about Defiler of Souls?

Never thought about it but it could work, I'll test it out.

fnchmtt

Thinking of replacing Bloodgift Demon with Ob Nixilis Reignited. Thoughts on that?

It could be better. His ultimate makes him better.

I think that that's a good idea, since he's the same mana cost for the same effect, but he can also destroy creatures or use his ultimate to just win.

Yes, he is now in. I also ordered a Rakdos Signet to replace Armillary Sphere. Toxic Deluge is next on the order list, I think,
