So this Prossh deck is pretty typical, although I have my own twist to it based on my personal deckbuilding style and budgetary constraints. I'm pretty pleased with the list so far, but I'm looking for constructive criticism and feedback to help me get some extra perspective on the build.

I think between Dictate of Erebos + Grave Pact that perhaps Black Sun's Zenith + Blasphemous Act are unnecessary. For now, I like I having a lot of board wipes. It helps control the board of course, but the positive side effect is that if Prossh is out, he can be recast after he dies, generating more and more Kobolds for you. Having four makes this more effective, but dropping one or both of the latter choices may be prudent in order to open another slot. That card slot could be another ramp spell, or game ending card, perhaps a different removal spell. It seems that I'd rather have a board wipe if I were to want a removal spell, so I'd likely have to throw in Artifact Mutation for a bit of both.

This deck is fairly fast, but of course the mana base slows me down sometimes with the variety of lands I have that enter tapped. ABU duals would be a Godsend for this deck. I don't run any infinite combos. Prossh is already so explosive that I keep it "fair" and it's still a powerful deck that's fun to pilot. So, I don't have Melira, Murderous Redcap, Deathbringer Thoctar, Triskelion, Mikaeus, the Unhallowed, or any of that jazz. I run Zealous Conscripts but no Kikijiki. That sort of thing.

I have Ashnod's Altar, but the best it can do is a really big Exsanguinate. Still a powerful play most of the time, but it's easily disrupted, so I'm ok with it.

I also have Tooth & Nail. This gets me Purphoros, God of the Forge, Craterhoof Behemoth, and/or Avenger of Zendikar 99% of the time. Purphoros + Avenger is a huuuge play, and I admit is pretty swingy, but at least it's not infinite. This may sound like I'm trying to avoid calling myself a hypocrite since I just said I was eschewing infinite combos like Food Chain, however I contend that, while powerful, this sort of play with Tooth and Nail is vulnerable to countermagic (no Boseiju) or Aven Mindsensor or something. Furthermore, I can just NOT get the combo and search up a couple random dudes like Blood Artist or Scooze. I think getting Zealous Conscripts first would be hilarious just to trick them into thinking I had Kikijiki, only to find a Farhaven Elf.

T&N also helps me find Prossh if he gets tucked. I run Diabolic Intent + Liliana Vess + Worldly Tutor specifically so that I can battle tuck effects. I rely so heavily on Prossh's ability to put Kobolds on the table that it can slow me down quite a bit without him around.

As mentioned, the manabase needs work largely due to the amount I have that enter the battlefield tapped. Any suggestions? Should I run the pain lands, such as Llanowar Wastes?

Cards on my chopping block:

I'll consider others of course since I'm hoping to receive some feedback from you folks! Thanks for reading.

P.S. Sideboard = cards to acquire. Maybeboard = cards I'm thinking about but already own.
