Xenagos, God of Revels would fit in nicely, not sure if you had him and took him out... Prossh as at 10/10 with haste can be pretty scary.

Did you try Crux of Fate instead of Damnation? 1 more mana but you get to keep Prossh/all your dragons.

Burn at the Stake is worth adding. It takes a relatively small amount of tokens, gets past blockers or any Propaganda/Sphere of Safety effects, and can surprise am opponent at an obscenely high life total (looking at Oloro rn)

Also have you looked at any other sac outlets like Carnage Altar or Phyrexian Vault? Both of which play similarly to Evolutionary Leap, which had become a recent favorite of mine.

+1 from me! I've been trying for the longest time to build a semi competitive jund sac deck with a devour subtheme. Have you tried any other devour critters / think any are possibly good enough? Also, this is one of the best non combo proshh decks I've seen in awhile, I might build this myself!

There aren't many good Devour creatures outside Mycoloth and SKullmuncher that are very good. They tend to be very threatening and are often removed quickly. Both SKullmuncher and Marrow Chomper are good because you declare devoured creatures after it is too late to counter them, guaranteeing the desired life or card draw.

Thromok the Insatiable is a very fun devour card I used to run, but I took it out because I more often was killed by him getting caught by Insurrection or the like. He would work well in a deck based around devour though.

Mycoloth and Preyseizer Dragon are also pretty great, but they need they also need to survive until your next turn in order to function

Dragon Broodmother doesn't devour by herself, but her babies do. I don't think I've ever paid attention to the devour trigger though, I'd rather use my creatures for other things. Still viable though.

For a commander, Prossh, Skyraider of Kher is really the only Jund-colored legend that creates tokens. A lot of devour creatures have a lower CMC than him, so you may find it difficult to be prominent early-game due to lack of creatures to consume.

Meant Skullmulcher, not SKullmuncher.

http://tappedout.net/mtg-decks/jund-edh-aggrocombo-1/I noticed you don't play Nim Deathmantle or Warp World so maybe you would benefit from check out my list.BTW Anything that gives creatures when a creature dies would help this list along I think you are missing a few. Such as Ogre Slumlord and Pawn of Ulamog or Sek'Kuar, Deathkeeper. All of which have great death triggers

I highly recommend adding custom categories to all the cards (card draw, card advantage, ramp, win con, token producer, removal, sweeper etc). That way you can easily determine if you have too many or too few of a certain type of card as well as lets you find cards that has no function, or an irrelevant function in the deck.
