WargRave on Rats all the way down

Needs more Rat Colony

With only 6 Relentless Rats you need half of your total number on the battlefield to even make them 4/4s. Most of the time they will be 3 mana 2/2s. You need a critical mass of Relentless Rats--at least 20. If you want to dedicate only a small portion of your deck to the Relentless effect, then Rat Colony is much better; unlike Relentless Rats it benefits from any rat you control, including Marrow-Gnawer's tokens. Pack Rat is also superior if you have many non-Relentless Rats.

Rat Colony is strictly better than Swarm of Rats. It's also generally better than Bog Rats, Carrion Rats, Muck Rats, Nezumi Cutthroat (fear isn't worth a large power loss and "can't block", especially when Marrow-Gnawer provides fear), Pestilence Rats (Rat Colony gets +2/-2 under most conditions and costs 1 less), and Earsplitting Rats (not enough graveyard/discard synergies).

Other suggestions

Tormod's Crypt -> Nihil Spellbomb, Bojuka Bog. You can run Crypt in addition if needed, but I would use these first.

Kitesail -> Bladed Pinions, Fleetfeather Sandals.

Geth's Grimoire -> remove. Only four or so cards in this deck actually cause an opponent to discard. Since you're running Ancient Craving, might as well slot in Ambition's Cost as well.

Nightmare Lash -> Lashwrithe. Or just run both, but Lashwrithe first.

Sword of the Paruns -> Bad Moon, Adaptive Automaton, Hall of Triumph, Vanquisher's Banner, and Obelisk of Urd are all more mana efficient and consistent ways to pump your rats.

Altar's Reap -> Costly Plunder, Night's Whisper, Sign in Blood.

I'm not sure how Shriveling Rot serves the deck.

There are two Cabal Strongholds, so one needs to come out. Cycling lands--Barren Moor, Polluted Mire, and Desert of the Glorified--hedge against land-heavy draws. Some cheap utility/value lands like Zhalfirin Void, Encroaching Wastes, Mystifying Maze, or Temple of the False God might be good over some number of Swamps too.

Phyrexian Tribute -> Scour from Existence, Unstable Obelisk. I know black is bad with artifacts, but there is a reason Phyrexian Tribute is in 55 edh decks, and the other two are in over 5000 each, and it isn't just color restriction. They cover all five permanent types instead of just one, including the equally hard-for-black enchantments. Requiring two creatures to sacrifice, Phyrexian Tribute isn't even always easier to cast, and it's effect is far less flexible.

Speaking of Unstable Obelisk, more mana ramp would be prudent, like Wayfarer's Bauble, Mind Stone, and Commander's Sphere. Bontu's Monument isn't Jet Medallion, but is still worthwhile with 27 creatures.

I don't think there are enough graveyard synergies to make Living Death appropriate.

Night Dealings is slow, does nothing if the battlefield isn't somewhat favorable, can potentially get removed, makes you reveal, and can't get lands. Razaketh's Rite and Mastermind's Acquisition tutor with no fuss. If you want slow, multi-card tutoring, Diabolic Revelation, Demonic Collusion, and Increasing Ambition are reliable options. Although none feature Nezumi in their art.

Curse of Death's Hold is a bit narrow for multiplayer; I'd prefer Ascendant Evincar which will hit more enemy creatures overall while buffing your own and being a 3/3 flier.

Haha if I were to make any changes to your list it'd start morphing into mine! But in the spirit of discussion...

I think Blood Artist and Zulaport Cutthroat can be cut. They are only really useful when you have an army on the field, and feel really lackluster otherwise. I understand that they result in an instant win with the GraveCrawler-Phyrexian Altar combo but you already have Plague Belcher. Your Unholy Grotto can pick up the Belcher from the GY so its a good enough package that you'll be able to draw into by the late game assuming you pack enough draw/tutors.

Adaptive Automaton and Metallic Mimic are frankly weak unless you can get a lot of zombies out. Zombie Lords are a fine balance because they allow you to multiply your zombie swarm's attack power, but alone they really suck. Imagine if I had an Adaptive Automaton out, I play a Diregraf Colossus which is buffed to a 3/3. I sac it to Gisa to make three 3/3 zombies. Or I could just cast an Archfiend of Depravity and sac it for five 2/2s. This is why I limit my lords to those that give useful abilities.

Carrion Feeder and Nantuko Husk are only good with a ton of zombies out. I would cut them. I don't think you need that many boardwipes as well, seeing as yours in not a control deck. If you are falling behind frequently enough to need that many wraths then its a sign that the zombie swarm deck needs to be built more aggressively!

You have put cards like Illusionist's Bracers and Magewright Stone to double up on Gisa's ability. I think these would be better served by just putting in good creatures that can be sac-ed. I would replace Thousand Year Elixir with Swiftfoot Boots which can serve double duty by protecting Gisa.

After these cuts you'll have space for draw and tutors. The best tutors cost a lot but cards like Diabolic Tutor, Liliana Vess, Increasing Ambition, Razaketh's Rite and Demonic Collusion should be cheap enough! You only need enough for you to get your finishers/combo pieces in the mid-late game. If you put in enough draw you won't need that many tutors.

For aesthetic : Whispers of the Muse, Night's Whisper, Demonic Collusion, Diabolic Revelation, Advice from the Fae. They have that advisor feel to them.

Hey thanks! Demonic Collusion sounds like a great add, and I'm always looking for more ways to fetch the Doomsday. Do you know any good boardwipes in these colours besides Damnation?

Misdirection and Foil are some great budget hard counters!

And Demonic Collusion is a great GY-based tutor. You can pitch two cards you want to bring back with Tasigur to buyback your tutor, and get whatever it was you needed.

luther on Kess, Dissident Mage

Ancient Excavation and Grave Upheaval are good because of the landcycling. Early game you pitch it to hit your land drops, and then when you need to use either you get it with kess later. Demonic Collusion and Capsize do well with kess since you can just buyback instead of exile. Increasing Ambition and Increasing Vengeance can get their flashback bonus for cheaper with kess. A couple of alternate ways to return spells might be nice, but Snapcaster Mage and Torrential Gearhulk can be pricey, so Archaeomancer and Mnemonic Wall would be some okay alternatives.

Hi! Neat idea! I really like it! +1!

I've got some good ideas for ya:

Zur the Enchanter will tutor for Arcane Adaptation. You could probably make him the commander for a guaranteed shot at Adaptation every game. I suggest you do that.

Here's my suggestion for an add on to the combo: Intruder Alarm. Now your combo is Near-infinite. IIIIIIIIF you make the Turbine a creature so it untaps when you grab a creature. This can be done with Ensoul Artifact(can be grabbed by Zur!), March of the Machines, Sydri, Galvanic Genius, Karn, Silver Golem, Toymaker, Tezzeret the Seeker (useful otherwise too), Tezzeret, Agent of Bolas, Karn's Touch, Xenic Poltergeist... you get the point. All the creatures would be Adapted Myr so they still help with the game plan. This side combo will make your main combo more powerful, allowing you to get all or your creatures rather than just one. Also you will additionally get infinite mana if you have a free mana-dork out. Something to consider.

Now regardless if you go with the side combo, you'll need a robust tutor package for consistency. Zur and a few others I've mentioned help, but here's some more: Enlightened Tutor, Diabolic Tutor, Razaketh's Rite, Demonic Collusion, Drift of Phantasms, Dimir Machinations, Mastermind's Acquisition, Brainspoil, Fabricate, and Beseech the Queen are all solid options.

Hope some of this helps! Let me know if you like or can't figure out the combo!

Love the combo! Gonna echo some thoughts here.

Razaketh's Rite, Demonic Collusion, Drift of Phantasms, Mastermind's Acquisition(Triton), Trinket Mage, Vedalken AEthermage, Dizzy Spell, Ethereal Usher, Netherborn Phalanx, Perplex are all a bunch of budget tutors you could consider. Many can do other things too which is nice.

Swan Song, Negate, Perplex, Lightning Greaves, Swiftfoot Boots may be a good start to a protection package for the combo.

Necrotic Ooze can act as a copy of the sphinx or Apostle if one of them is in the 'yard.

Also going to second cdkime. Thrumming Stone and a few big demons will serve as a good backup plan.

Hope some of this helps ya!
