Yahenni, Undying Partisan

Legendary Creature — Aetherborn Vampire

Haste

Whenever a creature an opponent controls dies, put a +1/+1 counter on Yahenni, Undying Partisan. (Dying is being into the graveyard from the battlefield, tokens are put into the graveyard before they cease to exist.)

Sacrifice another creature: Yahenni gains indestructible until end of turn.

Yahenni, Undying Partisan Good to have a separate threat going in the background, this single card acts as insurance for the deck. Be it as a lightning rod or the last thing standing after everything goes to shit.

Update!

Out: Bloodhusk Ritualist

In: Yahenni, Undying Partisan

Bloodhusk Ritualist doesn't really fit with the theme of going wide and gaining +1/+1 tokens, whereas Yahenni, Undying Partisan does. I think sacrificing vampire tokens to make Yahenni indestructible for a turn might be pretty powerful as well.

LoTS I think going into 2 colors would help you for sure. Adding red would give you a LOT more power in those 2 red cards I mentioned earlier.

As to why the cards I mentioned are "bad":

• Demonlord of Ashmouth is a lot of mana and doesn't really do anything other than kill a bunch of your own creatures. 4 mana is a LOT in modern, so anything costing this much needs to provide a huge amount of value (common 4 mana cards in modern include Bloodbraid Elf, Omnath, Locus of Creation, Yawgmoth, Thran Physician and Urza, Lord High Artificer, which can each single-handedly turn the tides of a game).

• Mortician Beetle is just another creature that becomes bigger over time. But "becoming big" isn't particularly useful on its own, especially if it takes a long time to do so. On its own, it's just a vanilla 1/1 that your opponent mostly doesn't have to care about.

• Typhoid Rats just doesn't do enough. Because it's a 1/1 deathtouch, it's basically resigned to sitting back to block for the entirety of the game (or swing for insignificant damage). It's not terrible, but its not doing anything particularly useful towards enacting your gameplan, so I don't see any reason why you'd want to run it.

• Yahenni, Undying Partisan is effectively just a really expensive sacrifice outlet. It just can't compete against all the much more mana-effective sacrifice outlets out there (Carrion Feeder, Viscera Seer, Goblin Bombardment), so it's just a case of it being too slow at what it does and there being better cards for the job

• Dreadhorde Invasion is just a very weak Bitterblossom. Bitterblossom is great because it lets you go-wide, creating multiple creatures (and those creatures importantly have evasion). Meanwhile, Dreadhorde Invasion puts all your eggs in one basket, that takes a lot of time to become big enough to matter. The amount of damage you can deal with this card is often very close to the amount of life you lose from having it in play.

• Whip of Erebos 4 mana card that does almost nothing, which then costs another 4 mana to temporarily resurrect a thing... it's all just too mana-costly - paying 8 mana to get a single creature back for one turn is faaar too slow and clumsy.

• Profane Command, like the Whip above, just costs too much mana to be of any practical use.

---

As for your decklist, I would think something like the following could be a strong direction to take it:

• 4x Gatekeeper of Malakir
• 3x Pawn of Ulamog
• 3x Shambling Ghast
• 4x Zulaport Cutthroat
• 4x Blood Artist
• 4x Mayhem Devil
• 4x Goblin Bombardment
• 4x Carrion Feeder
• 4x Smallpox
• 4x Lightning Bolt
• 22x Lands (mostly black, but with some Bloodstained Mire and Blood Crypt for red)

Some thoughts:

• your land count is very low, and your quantity of high-cmc cards is higher than it should be. I’d suggest going to 22-23 lands, and running no more than 3-4 cards costing 4cmc.

• you currently have almost nothing to gain from all your various sacrifices. At the very least you should be running playsets of both Zulaport Cutthroat and Blood Artist. Having lower-mana sac-outlets (like Carrion Feeder or Viscera Seer) is probably also advised.

• consider more controlling-sacrifice options like Smallpox.

• If you’re able to splash green, i’d highly advise both Grist, the Hunger Tide and Unearth also (I wouldn’t bother playing Unearth without Grist).

• If you’re able to splash red, a playset of both Mayhem Devil and Goblin Bombardment would do wonders. If you can only splash one colour, the red splash is far stronger than green.

• a bunch of just “bad cards” i think you should ditch entirely are Demonlord of Ashmouth, Mortician Beetle, Typhoid Rats, Yahenni, Undying Partisan, Dreadhorde Invasion, Whip of Erebos, and Profane Command. I can go into more detail on why these cards are bad if you’d like.

Immersturm Predator is fine, but there are better choices in my opinion. Yahenni, Undying Partisan has many of the same upsides, but comes out for less mana and less colors. Immersturm is probably better than Falkenrath Aristocrat in my opinion, though I haven't tested it.

Krav, the Unredeemed similarly there are just better options out there. Yawgmoth, Thran Physician is obviously miles better, of course, these cards cost more $$ as well, so that's a consideration for sure. However, my budget list doesn't run these guys either, to be fair. A main concern is definitely that it both costs 5 to play AND has an activation cost on top of that. It's super important to play this kind of deck as fast and low to the ground as possible.

Juri, Master of the Revue is basically just a Lightning Bolt most of the time. It's not like that's terrible, but I'd rather just run something more impactful like Plaguecrafter as a means of controlling the board.

Black Market I've never really felt like I needed the mana from this honestly. Especially with the relatively easy access to 2MV mana rocks these days. As long as you have a decent amount of card draw you should be fine in most games in my opinion.

Terror of the Peaks is basically a better version of Flayer of the Hatebound so if you had wanted to run that, then Terror of the Peaks is the way to go. You can see in my primer that I don't think the effect is too important generally though. It's a high mana value card that requires you to already have a lot of other pieces in play to really take advantage of it, and I think there's better payoffs you could be running comparatively. It's best in a slower meta, but it's certainly playable as a top end of your mana curve card though.

Would you consider putting in Yahenni, Undying Partisan rather than Kels, Fight Fixer? It's a cheaper (mana wise) version of more or less the same effect, whilst also being an awesome attacker after triggering Nev.

Pretty good starting point, one of the things to keep in mind in Commander though is generally, you're expecting a 4 player game that lasts a long time, so you want to prefer cards that can have major impact in the early game or the very late game, something like Act of Treason is pretty limited in terms of when it will be really useful, cards with similar effect but with more power or flexibility (one of which you found in Insurrection) will serve you better in most games. Consider instead something like Harness by Force or Captivating Vampire.

The other thing to consider is ideally, if you're stealing creatures from your opponents, you want to make sure they don't get them back, Indulgent Aristocrat and Yahenni, Undying Partisan are good examples, but ideally you want as many of those sort of effects as you can fit in, Viscera Seer, Bloodflow Connoisseur, and Immersturm Predator are all decent vampire options, though you also can find things like Carnage Altar that can give you some extra value from your steals.

Single target removal like Terminate and especially Doom Blade are probably unneeded for you. If you need to kill a single target your plan is probably better focused on stealing it and sacrificing it instead. You probably are better off with a few more board wipes instead, if you do fall behind or lose place, you'll want a few more reset buttons. Kindred Dominance is an expensive but really powerful option for Tribal decks, Decree of Pain hits you as well, but it's a much cheaper card and great for if you're running out of gas in the late game. If you do want single target removal spells, again, you want flexibility, consider Bedevil, for just one mana more than Doom Blade you remove the restriction, and now can deal with much more than just problem creatures.

All in all though, like the list as a starting point, you'll figure out what you need and what you can cut best by playing the deck, so good luck!

Right on, I added the Fatal Push. After investing in Bloodghast, I decided to make it a little less budget, short of Sorin, Imperious Bloodlord (for now). I also temporarily added two Yahenni, Undying Partisan for both the haste and sac opportunity. I honestly am not sure if this card is good or not, but it does help with the 3 cmc part of my mana.
