Thanks for all the suggestions!
To answer some of the questions, then yes, being creatureless is solely a restriction I put on myself. Added creatures would surely make it more powerfull (check GloriousGoose's deck fx). Secondly, like most of my decks, I don't try to make them as effective as possible. I tend to play cards that looks fun to play or fits the theme - but setting that aside, you all brings up some solid advice and I will most properly make some adjustments. So thanks for that!
Toxic Deluge should properly be here. I think the reason why I left it out, has something to do with playing various sac-effects, so maybe I didn't think I needed to be able to take out indestructibles. That and that Erebos tends to suck a lot of life out of me! Sometimes I get very greedy with him. Thats also the reason why I play Venser's Journal. I understand why people think it's bad (and it properly is), but the lifegain can get real and a why to keep drawing deeper. It has done some solid work for me, so I don't think I'd cut it anytime soon.
Black Market also used to be in the deck, and I could totally see it returning.
I'm not a fan of planeswalkers. As with creatures, they would porperly make a great addition for the deck and playstyle. I knnow the power of Necropotence, but like 3drinks said, if you like to play out of your graveyard, you shouldn't play it. It might not be a dedicated graveyard deck, but I do discard a lot and I just like to have the possiblity to play whats went in there.
In a strategy dedicated towards leaving opponents emptyhanded, the inclusion of symmetrical card draw raises eyebrows.
You most mean Mikokoro, Center of the Sea since I don't see that much else besides Dark Deal and Geier Reach Sanitarium. Well, the reason is I decide when to activate them. When your opponents are hellbent, using Mikokoro before their upkeep if Bottomless Pit down, usually isn't that dangerous. Plus it can feed them cards to discard. Same with Dark Deal and Geier Reach.
How are you breaking the symmetry on Descent into Madness? Without a constant stream of tokens to help buffer the exile I feel like you probably end up worse off than the rest of the table, but maybe I'm missing something.
Having a drawengine in the cz have been my reason for it's inclusion and breaking the symmetry, but I think I should properly cut it, though I really like the name and effect, but overall it's waaay to slow.
This deck seems really weird to me. I have a hard time imagining it doing good in my area. Purely because its win-conditions are slow and they kill people in a way that is highly annoying. For example Painful Quandary is super strong, but I've found cards like that rapidly turn the game into archenemy until you're dead.
Also, I assume there isn't many super-friends decks in the metagame because this deck looks extremely weak against planewalkers.
Well, monob is also very, very weak against enchantments and artifacts - that doesn't shy me away from playing that colorpie.
I don't understand Venser's Journal. I feel like its to help cover the life loss from your general. Yet, you're also running Null Brooch.
Crucible actually used to be in the deck, but removed it since another deck needed it. Think I'll put it back. Mindslicer is a creature Sometimes I don't have many cards in my hand too, then Null Brooch is awfully good in a deck that can't do much to certain cardtypes. Also, since my wincons is permanents, having Null Brooch online can be a security for said wincon. It has simply saved me too many times for me ever to cut it.
I won't suggest creatures as that seems to be the theme, which I dig - restriction breeds creativity, and if you want creatureless that's fine by me (although all the enchantments would tempt me to add Doomwake Giant). Is that often an issue for you though? If so, you could always include some ways to get chump blockers - Bitterblossom seems great here for that, or Dreadhorde Invasion if you can't the afford the superior original. Even Zombie Infestation gives you something to keep your life totals up. Or you could just run Darkness, Thaumatic Compass and such. Compass could be really good here actually, as a ramp and as a second Maze.
I think you missed a line here, but yeah the deck tends to draw a lot of hate, so I might be inclined to add Thaumatic Compass as another Maze.
Have you considered Thoughtseize et al. as a proactive way to pick off problems like artifacts/enchantments or counterspells before they can affect you? In my experience, pinpoint discard is underrated in the format. I wouldn't pack more than a couple, but they're more versatile than most people realize. On the other hand, since your goal is to put the whole table into topdeck mode they might not be as good. Having played Pox in Legacy somewhat casually I can attest to how frustrating it is for someone to draw and immediately play something like Jace, the Mind Sculptor while you're staring at Thoughtseize in your hand.
Torpor Orb might be okay. It looks like you run only three cards it would blank, but Enter the Battlefield Dragon Highlander is a thing. I ran it for a long time but added in a few too many ETB triggers which severely weakens the card. Dying to combat damage when you had to cast Gary with it out is miserable.
There's also Last Laugh. It ain't good, but it's fun. You'll end up killing yourself sometimes but that's the cost of doing business in MBC.
A second mono-black deck in a row, but this one is far from creatureless. This deck plays a whole pile of creatures into the general Endrek Sahr, Master Breeder, feeding a litany of sacrifice outlets and aristocrats style death triggers to ride to victory.

Zedruu: "This deck is not only able to go crazy - it also needs to do so."
I'm unsure as to how strong the discard theme actually is, as once an opponent sets up some kind of crazy engine, they can pretty easily ignore single discard effects. The targeted discard options are excepted.
I like Reassembling Skeleton a LOT more than endless cockroaches. Sure, the latter triggers Endrek, but the mana savings is pretty important for an effect that you mainly want to use when you just want to sink your mana.
I like Bloodghast more than both, because it doesn't require you to pay mana. IMO, in EDH if you are spending on mana sinks, it means you either have way too much mana for your own good, or you have nothing better to do. I like being in the former category, and this list is built to be that. Still, until you get there I wouldn't value mana sinks TOO highly.
This deck also has no instants and no boardwipes. Be very careful of players killing you out of nowhere.
Awesome - the whole deck is sort of one big combo. You need something that gives you mana for sacking creatures - like the altar or one of the treasure makers, something that draws a card when a creature you control dies, and Endrek. You'll probably need a Blood Artist effect as well, given how black is with every effect also costing one life. Then, once you cast a creature, you can sac the resulting thrulls and draw that many cards and make that much mana to cast another creature of equal or lesser value. You can often go on indefinitely, especially if you start with the high cmcs and work down. Shoot for a Gray Merchant of Asphodel to close out once you feel comfortable. That's the flashier win. Odds are, you can just plop down any Blood Artist effect and win off repeated sacrifice in the same combo. Endless Cockroaches and one of the mana makers goes infinite as well. That's the goal. In the mean time, you should have plenty of ways to keep hands and board states empty. There's a lot of support for a big mana sub-strategy, but it's mostly just backup incase my pseudo-storm wincon stumbles. There's nothing cooler than drawing out your whole deck and playing every creature. Big mana smooths out the ride incase the CMC rollercoaster doesn't go your way. Ideally, Endrek is the last thing you need, so that 5cmc doesn't feel like it's holding you up.
Oh boy, if your main goal is to combo out, I've got lots of recommentions for you! (I have a Endrek Storm build)
I'll second Carnival of Souls. It's a central piece in my combo, and can keep your storm count going on for a long time.
It looks like you have a hard time assembling your combo without tutors. Ad Nauseam is properly the best card in my deck, and when I resolve it, it properly means I win. The ommission of Ashnod's Altar is strange. Granted it doesn't make B, but it's one of the strongest sac-outlets IMO. With Initiates of the Ebon Hand you can bypass the colorless. Or you can just use said colorless to put into an indefinitely large Exsanguinate.
Instead of bigmana, you could focus on bursts instead playing rituals, and there's also SO many rituals on black creatures. Priest of Gix, Blood Pet, etc. Also creatures that put tokens into play plays nice with Endrek. The best would properly be Sengir Autocrat, Weaponcraft Enthusiast and Marsh Flitter
Does Kothophed, Soul Hoarder do anything good for you? It's only triggered by opponents permanents...
Is your deck purely permanentbased since you don't play a single instant/sorcery? You miss out on a lot of wincons by not doing that, Tendrils of Agony, Bitter Ordeal.
I think it looks like a nice deck and I do not really have many good suggestions, but a few: Sifter of Skulls and Pawn of Ulamog - does seem to be roughly the kind of cards you want, on death trigger, tokens, mana (not colored, but still). Deserted Temple - generates 1 less than your best land (better than cabal stronghold with cabal coffers in play). That still seems reasonable to me for a colorless land that comes into play untapped (it can also give you colorless in the beginning).
maybe: Gate to the Afterlife - more on death triggers, life and looting.
Endrek Sahr, Master Breeder is one of my favorite commanders. The ability is so flavorful and so powerful when built around that its just loads of fun to play. And its powerful in a totally fair way.
Some cards that I really like in my list that I think would be a good fit in your list are some of the following:
Bloodghast, Nether Traitor - I like to have some cheap cards that can self-recur and I have found that these two are the best. Bloodsoaked Champion is also pretty good. Priest of Forgotten Gods - This is a fairly new card that I have been absolutely loving in this deck. It's so cheap and generates so much value that its become one of my favorite cards to see early in the game. Mikaeus, the Unhallowed - One of the best recursion engines available, and since you aren't running Triskelion there is no danger of going infinite. However, you do have a ton of EtB abilities that would be amazing to double up on on top of getting two shots at sacrificing each non-token creature. Death Cloud, Eliminate the Competition - I'm amazed that this deck runs zero instants/sorceries and even more amazed that you don't run some form of mass board wipe. Both of these cards take advantage of you having plenty of creatures that you are willing to sacrifice while leaving other key creatures alone. Spawning Pit - I like your suite of sac outlets, but I think you should also consider Spawning Pit. It's free to use when you need to sac something, taking all those Thrulls and turning them into 2/2 creatures to feed your sac outlets again is very very satisfying.
I also don't run discard effects in my build, but if I did I would probably be running Tar Fiend.
Good luck with the deck and happy Thrull breeding...
The discard was a strange byproduct of the way I build decks, where I don't like one-of effects. When I got done adding in everything that was like Fleshbag Marauder, I had to include Plaguecrafter, of course. Then I felt like I also needed all the other ETB guys with similarly worded discard. Then I felt like I had two mechanics I needed to go in on with -- edicts and discard and searched out repeatable outlets for both. Anyhow, my decks very quickly build themselves because I think in broad categories.
Everything is better with flash, and green creatures are very far from an exception to that rule. And if your opponents are as flighty as I am when playing magic, they will never ever remember not to attack into a commander that's an Ambush Viper. I've attacked into a Yeva's "empty board" an embarrassing number of times.

Zedruu: "This deck is not only able to go crazy - it also needs to do so."
Patron of Orochi and Verdant Sun's Avatar seem poor to me. I don't think 8 mana is good for ramp and I don't think a 7 mana 5/5 that gains 5 life will ever be good enough. I feel like you would be better off with Beast Whisperer and with more ramp. If you really want life gain, then I think something like Loxodon Warhammer would be good... since it also lets you trample.
I noticed no sol ring and no Elvish Mystic and other 1-mana ramp spells... I am guessing there is a reason for this.
Ooh, this one is right down my alley on account of Nissa. Yeva is crazy strong, she can win outta nowhere. Well, it seems like nowhere, but Yeva had a plan all along. This one definitely looks like a pretty well tuned, more aggressive deck than my toolbox-y shell, but I might be able to give some recommendations, or at least start some discussion around areas the deck could cover.
Firstly, no Dryad Arbor? It's a classic turn one drop with Green Sun's Zenith to get you off on the good foot, and gets your Birthing Pod chain started at the very bottom. Bare minimum if it does nothing else it triggers your Soul of the Harvest et al. It's probably not a huge deal either, but I wonder whether you'd make use of Winding Canyons and Emergence Zone - I guess it depends how much grief Yeva gets.
How much value has Joraga Treespeaker given you? I count 5 elves in the list. I guess it's a good mana sink, but there are probably better uses for your free mana, and probably better ways to ramp a little. At a similar point in your curve you could run Lotus Cobra if you need incidental mana, or run things to take advantage of your ETB ramp (more later*).
Duskwatch Recruiter is nice in terms of cost reduction, but how often does it flip? Seems like it'd be tough to work around for a fairly small benefit. I don't have an obvious suggestion for replacement in terms of what it does, but in terms of your Pod chain, perhaps Elvish Visionary would suffice? Likewise with Magus of the Library, how often does it do what you want it to?
Timbermare I'm assuming you run to make sure you're swinging into an open board, right? I'm not aware of anything that does the same at that CMC, but Siege Behemoth is a thing, and you don't need to worry about it dying to Echo.
I like the effect on Primordial Sage, but it's no Soul of the Harvest. I've been running Beast Whisperer instead, and it's been a really solid add. Likewise, Zendikar Resurgent is obscene. Usually once I land ZR I can end the game shortly afterwards. I mention these purely because they're both on your maybeboard - either one would likely do better than Primordial Sage - I'd rather pay 2 less for the same, or pay 1 more and get a mana doubler.
Ulvenwald Hydra - do you run this as a beater, or to pick up specific lands? If it's as a beater, I'd strongly suggest Multani, Yavimaya's Avatar as a better one. It's very rare that I have him on the field as less than 15/15 or so. With flash, that's scary.
So, it's less prevalent in your deck than mine, but still there to some extent, and eminently abusable. ETB triggers are really an angle you could use to hit the gas super early. You're already running one of my stalwarts to leverage these triggers in Temur Sabertooth, how do you think Cloudstone Curio, Bramble Sovereign, Panharmonicon or Wirewood Symbiote would fit? It means you can ramp again and again, get multiple Terastodon triggers, and with Avengerhoof in here already, you can make sure you win. Not only that, these pieces help you protect your board when needed. It's a strong synergy to go for in green, although I understand if you don't have the room for it in your build.
Looking at the rest of your maybeboard, I can also strongly recommend Karametra's Acolyte. Gross things happen when she gets cast almost every time in my build. I'd look at finding room for her, she's fantastically good.
All in all, this deck looks pretty solid, and pretty fearsome to play against. Hope the above helps, if not they're always talking points at any rate

I noticed no sol ring and no Elvish Mystic and other 1-mana ramp spells... I am guessing there is a reason for this.
Been quite a while since I played Yeva (though I do often think about putting her back together, was a fun deck), but I've gottta give a mention to my favourite card in the deck - Arboria. Sure, it's janky, but it actually worked really well.
Other than that, I'll second toctheyounger77's suggestion that getting in ways of reusing your ETBs works really well with Yeva. Cloudstone Curio was a key part of my deck. Sort of tying into this, I'd like to see a few more cheap utility/value creatures like Reclamation Sage, Manglehorn and Generous Patron. Even without ways to reuse the ETBs, have good cheap plays really helps, and if you can reuse them.... Rec Sage in particular is fantastic with Yeva - instant speed interaction is great.
I'll actually defend Patron of the Orochi here. The mana boost that thing gives Yeva is insane and should probably stay. True, Seedborn Muse is better, but this effect is just so good in here that a kinda crappier version at 8 is still perfectly slot-worthy.
I'd dime the creature cast draw, you've got Beast Whisperer, Guardian Project and Zendikar Resurgent in the maybeboard, promote them to main. You could consider Cloudstone Curio for various ETB-juggling shenanigans. Shamanic Revelation also sounds like a pretty good idea. The list is oddly ramp-light, you could consider adding various time-honoured classics of the 2-4 CMC varieties. Arboria is also cute, I hear.
If I was doing Yeva, I would likely put as many untap permanents into the deck as possible (so you could treat each players turn as your own), which would make me rate things with tap effects higher. I think that would be a major change though, still, I guess I could mention Awakening as an option. Yes, it untaps everything for everybody, but you are likely way better off than everybody else for that effect.

"Hail to the speaker, hail to the knower; joy to he who has understood, delight to they who have listened." - Odin
I like the Orochi here, the mana boost on your own turn can be very valuable and it makes everything kind of going on working without Yeva. With the numbers this deck manages in terms of P/T, the extra muscle looks good.
What so you think about the new Vivien for a bit of redundancy?
I've been a huge fan and avid advocate of Yeva, Nature's Herald since forever, so i'm very happy to see a deck with her at the helm here!
Aside from several good suggestions above i find the avg. CMC in combination with the "lack" of early ramp to be rather akward. Birds of Paradise i great ramp and also a fantastic flying surprise blocker in this deck. The usual 1-drop Elves wouldn't hurt anyways.
There's not a ton of disruption in the deck either. I'd consider Song of the Dryads, Lignify and the new Return to Nature from WAR.
What [d]o you think about the new Vivien for a bit of redundancy?
I've just included Vivien, Champion of the Wilds in both my Ezuri, Renegade Leader as well as my Mirri, Weatherlight Duelist deck and i can say she's more than "just" redundancy. Her + can make her very hard to kill and her - is classic CA, so you won't be mad drawing into her when you already have your commander out. Definite suggestion on my behalf!
I'd consider Song of the Dryads, Lignify and the new Return to Nature from WAR.

These are all pretty good ideas. I've run Manglehorn in the past in Nissa, and Reclamation Sage is a stalwart.
As far as disruption goes, it sounds weird and counter-intuitive, but I'm going to recommend Wave of Vitriol. That card is no joke. The amount of games people scoop after it resolves is hilarious, and it really does make things a ton easier for a mono green creature based deck. It's a death sentence for Theros Gods too, which is sometimes nice considering how persistent they can be.

Wave of Vitriol is absolutely amazing. I run it in my Rashmi, Eternities Crafter "Oops, All Spells" deck, which has literally three nonbasic lands and zero artifacts/enchantments. I assume it will work similarly in a creature based deck that runs almost entirely on Forests. You lost (almost) zero momentum and hardly anyone ever sees it coming. I also recommend this card.
In my mono green decks, I usually run Arena to use as removal in a land slot. I'm sure it's been outclassed, but maybe it would be worth it for your deck?
Card advantage is not the same thing as card draw. Something for 2B cannot be strictly worse than something for BBB or 3BB. If you're taking out Swords to Plowshares for Plummet, you're a fool. Stop doing these things!
To answer some of the questions, then yes, being creatureless is solely a restriction I put on myself. Added creatures would surely make it more powerfull (check GloriousGoose's deck fx).

Are the "2, sac a creature: draw a card" cards worth it? I would rather play some more free sac outlets like Spawning Pit or Altar of Dementia or the already mentioned Ashnod's Altar or even Blasting Station, Culling Dais and Grafted Wargear. Not paying for things works well.
They all seem like really likely additions to the list.

OCPunisher: Yeva Flash
Everything is better with flash, and green creatures are very far from an exception to that rule. And if your opponents are as flighty as I am when playing magic, they will never ever remember not to attack into a commander that's an Ambush Viper. I've attacked into a Yeva's "empty board" an embarrassing number of times.
I noticed no sol ring and no Elvish Mystic and other 1-mana ramp spells... I am guessing there is a reason for this.

So, it's less prevalent in your deck than mine, but still there to some extent, and eminently abusable. ETB triggers are really an angle you could use to hit the gas super early. You're already running one of my stalwarts to leverage these triggers in Temur Sabertooth, how do you think Cloudstone Curio, Bramble Sovereign, Panharmonicon or Wirewood Symbiote would fit? It means you can ramp again and again, get multiple Terastodon triggers, and with Avengerhoof in here already, you can make sure you win. Not only that, these pieces help you protect your board when needed. It's a strong synergy to go for in green, although I understand if you don't have the room for it in your build.
Looking at the rest of your maybeboard, I can also strongly recommend Karametra's Acolyte. Gross things happen when she gets cast almost every time in my build. I'd look at finding room for her, she's fantastically good.
All in all, this deck looks pretty solid, and pretty fearsome to play against. Hope the above helps, if not they're always talking points at any rate
Shamanic Revelation - 2 birds, one stone.
Other than that, I'll second toctheyounger77's suggestion that getting in ways of reusing your ETBs works really well with Yeva. Cloudstone Curio was a key part of my deck. Sort of tying into this, I'd like to see a few more cheap utility/value creatures like Reclamation Sage, Manglehorn and Generous Patron. Even without ways to reuse the ETBs, have good cheap plays really helps, and if you can reuse them.... Rec Sage in particular is fantastic with Yeva - instant speed interaction is great.
I'd dime the creature cast draw, you've got Beast Whisperer, Guardian Project and Zendikar Resurgent in the maybeboard, promote them to main. You could consider Cloudstone Curio for various ETB-juggling shenanigans. Shamanic Revelation also sounds like a pretty good idea. The list is oddly ramp-light, you could consider adding various time-honoured classics of the 2-4 CMC varieties. Arboria is also cute, I hear.
What so you think about the new Vivien for a bit of redundancy?
Aside from several good suggestions above i find the avg. CMC in combination with the "lack" of early ramp to be rather akward. Birds of Paradise i great ramp and also a fantastic flying surprise blocker in this deck. The usual 1-drop Elves wouldn't hurt anyways.
There's not a ton of disruption in the deck either. I'd consider Song of the Dryads, Lignify and the new Return to Nature from WAR.
Other than these it's a solid looking deck. I've just included Vivien, Champion of the Wilds in both my Ezuri, Renegade Leader as well as my Mirri, Weatherlight Duelist deck and i can say she's more than "just" redundancy. Her + can make her very hard to kill and her - is classic CA, so you won't be mad drawing into her when you already have your commander out. Definite suggestion on my behalf!
These are all pretty good ideas. I've run Manglehorn in the past in Nissa, and Reclamation Sage is a stalwart.
As far as disruption goes, it sounds weird and counter-intuitive, but I'm going to recommend Wave of Vitriol. That card is no joke. The amount of games people scoop after it resolves is hilarious, and it really does make things a ton easier for a mono green creature based deck. It's a death sentence for Theros Gods too, which is sometimes nice considering how persistent they can be.
Wave of Vitriol is absolutely amazing. I run it in my Rashmi, Eternities Crafter "Oops, All Spells" deck, which has literally three nonbasic lands and zero artifacts/enchantments. I assume it will work similarly in a creature based deck that runs almost entirely on Forests. You lost (almost) zero momentum and hardly anyone ever sees it coming. I also recommend this card.
