41 land seems to be overkill. Cut at least 3 land and if you still want the mana, add some mana rocks/dorks (though you have some already).

Skullclamp could provide you card draw with Reassembling Skeleton Prosh, Ulash, or your 1 toughness creatures.

Abrupt Decay can be limiting in EDH. Many people's deck average CMC is close to 4.

Chaos Charm is a really weak one time effect card.

Lightning Greaves seem like a better fit for you than Swiftfoot Boots .

I'm not a big fan of Desecration Demon in EDH. Try Bloodline Keeper  ^Flip .

Kalonian Hydra would fit well in here.

Anger seems like a much better way to get haste than some of the methods you are using. He is sac fodder for Prosh and you could add Entomb to get him in the grave as well.

Jund Charm seems underwhelming. If you want the grave hate you could add Bojuka Bog in place of a swamp and use the charm's slot for something else.

I don't see the point of Slitherhead . Very small effect.

Mogis is pretty ineffective in EDH. You could get a lot more out of Purphoros, God of the Forge - one cast of Prosh would net you 14 damage to each opponent.

Yavimaya Elder fits as great ramp in your deck since he's a sac-able creature that generates you cards.

Things like Hornet Queen , Myr Battlesphere and Siege-Gang Commander can give you creatures to sac to Prosh or Skullclamp while having other utility.

Krenko, Mob Boss can get you a lot of creatures over a few turns.

Ashnod's Altar can give you a sac for mana mechanic which could be useful if you add more creature generators, Skullclamp, or some X spells... Speaking of which Profane Command is an extremely good card. It can be a game winner with life loss/fear or a tool to help you back in the game by -X/-Xing a creature and returning one of yours to play.

You should add some enchantment/artifact destruction. Krosan Grip Consign to Dust Golgari Charm .... I don't think you have quite enough, though it depends a bit on your meta.

Eternal Witness is a great way to smooth out limited assets by giving you a way to reuse what you need.

You seem very reliant on Prosh. I would try to tune some damage strategies beyond him so if Prosh gets answered you aren't left treading water.

I also really think you need to refocus your card draw - it seems like you'd run out of steam at some point pretty consistently with so few ways to recur used cards or generate new ones. Skullclamp is a must but other things include Phyrexian Arena , Underworld Connections , Into the Wilds , Cream of the Crop , Sensei's Divining Top , Greed , Erebos, God of the Dead , Staff of Nin ........ Some options to keep in mind if you find yourself running low in longer games.

Thanks for the suggestions Ohnoeszz

I would definitely like to add some of the cards you suggested to the list. Right now I am just trying to trade for stuff because I am trying to save some money. But I will be on the lookout!

You could take out a land for a Solemn Simulacrum.

Sorry, Ruffigan. I reset the comments right after you commented -_-

Blade of the Bloodchief and Doubling Season will let Prossh deal 41 points of damage in one hit.

I definitely want a Blade of the Bloodchief now

Looks crunchy.

Reaper of the Wilds? I see that Viscera Seer, but why not another?

Reaper of the Wilds looks very nice for this deck, I have seen that card but have never really read it. Thanks!

Looks fun! I would add in Nature's Lore and Skyshroud Claim cuz they are bonkers ramp, and most importantly, can search for shocklands. Just to add more consistency to the deck, I would add in fetches. They are a bit of money but u can trade for a few at fnm. Off color ones like Windswept Heath are still good (and legal to play) cuz of shocks as well! Demonic Tutor and Vampiric Tutor are good, and, if u get them in shitty condition, which is how I got mine, pretty affordable! also Exploration/Burgeoning >>>>>>> Krosan Wayfarer. I might cut Boundless Realms cuz once ur at 7 mana, u prob have betting things to spend ur turn doing :).

Okay, thanks for the suggestions! Don't forget to +1

Food Chain? It creates infinite tokens and infinitely large Prosh.

Oops, didn't see the infinite combos thing! Sorry! :P

Not a problem Scorprix, I'll probably end up caving and adding it in anyways, ha! Thanks for the suggestion, though!

It seems like more often than not, Exploration would generate more value than Krosan Wayfarer.

Exploration or Burgeoning I am definitely wanting to obtain for this deck. I forgot to include it in my Maybeboard. Thank you for reminding me,
