(description in progress)

I am Yahenni.

Socialite of Ghirapur. Ally of the Gatewatch. Born of Aether.

Philanthropist. Revolutionary. Murderer. Savior.

I was many, many things over my short time on this plane, a fact for which I am grateful. If life is indeed change, as the philosophers say, I have had a long life indeed (if you don't count in years).

The Aetherborn are born from the magical residue of aether production on Kaladesh; I am basically walking, talking industrial waste. We do not live long - three or four years, at the most, spending the time trying to experience as much of life as possible.

I was born with a rare gift - I could extend my life by consuming the energy of others.

Enough to see the cycle of seasons a few times, and enough to appreciate the value of the little life we are given - perhaps more than the other beings of Kaladesh possibly can.

This deck is pretty basic mono-black control, with an emphasis on board wipes and token production (preferably from non-creature sources). As long as you have a creature to sacrifice, Yahenni is basically immortal in combat and invulnerable to board wipes. Any board wipe should also make them much, much larger - at which point you can easily swing for commander damage to win.

Main combos: Eldrazi Monument+ Tombstone Stairwell is disgusting, and both pieces are amazing for the deck alone. Mikaeus, the Unhallowed+Walking Ballista+Yahenni, Undying Partisan is a combo-kill on the whole table. Magus of the Abyss + Lightning Greaves can be a surprisingly hard lock. Ogre Slumlord+Attrition is a machine gun against opponents' creatures.

Play the long game, protect your commander, and let them over-extend. A creature with shroud and haste is pretty close to immortal in a normal EDH game...and you can quickly murder the table if you play cleverly.

A better description is coming soon :)

Suggestions (and +1s), as always, are welcome! Help me optimize this deck!

Happy deckbuilding, and if you want to leave a +1...

Abhorrent Overlord seems pretty good for you, spitting out a bunch of tokens you can feed to Yahenni (although TO's telling me you've already considered it, I'm leaving it in anyway cause it's good). Phyrexian Reclamation would be nice for getting back things you've sacrificed. I'm a firm believer in the power of Beacon of Unrest and Ever After as reusable reanimators as well.

Have you thought of Aetherborn Marauder , Midnight Entourage , or Gifted Aetherborn for possible creature flavor. But I'm still new to building efficient EDH decks.

Krallion: Curse of the Cabal's suspend is bad outside of 1v1 (and even there it's marginal. Oubliette is a very bad Oblivion Ring and costs $20. Tawnos's Coffin costs $40 and doesn't do enough for its mana cost or activation cost. Undercity Plague is too much mana, I'd rather just play Smallpox and hit everyone.

PhotogenicParasympathetic: The issue with Abhorrent Overlord was that, although it does produce a lot of tokens, 1) it's high mana cost in a deck that already has a higher curve than I'd like and 2) having a lot of tokens makes my board wipes hurt me more. I generally prefer things that generate one of two tokens repeatably.

Phyrexian Reclamation was in here originally but I eventually swapped it for plain-old Reanimate. I'm not a fan of Beacon of Unrest here (I have almost no ways of placing good artifacts into opponents' GYs and I have few in my own deck good enough to justify the 5 mana), and although I like Ever After as a card I'd generally think it's overcosted? Have you had good experiences with it?

Jokester1393: This deck isn't really based around flavor, but I'd almost consider Aetherborn Marauder for that reason (best flavor text ever, and it plays halfway nice with Yahenni). I'll look into it, hehe.

Thanks you all for your comments! :)

January 28, 2017 12:46 p.m.

Well, the mana requirement is an issue, sure. I disagree on the situation with board wipes - I tend to think along the lines that if you've got a lot of tokens you're less likely to need a board wipe. That said, given your commander's indestructibility, it makes sense.

I have actually had great success with Ever After, although admittedly that's as part of an overly convoluted combo kill that no one sees coming because it's dumb and takes like 20 pieces. That said, it's still good value - 3 mana each for your Grave Titan and Massacre Wurm at the same time isn't a bad investment. It's no Reanimate, but it's certainly worth a try.

January 28, 2017 1:42 p.m.

Daedalus19876 says... #5

PhotogenicParasympathetic: I'll consider it :) I think I'd play Victimize over it, though, since I usually have at least a few tokens sitting around.

What's your combo? I have a deck like that, with 20-card chains of reanimation, if you want to take a look haha.

January 28, 2017 1:46 p.m.

Mine is Phyrexian Altar, Mitotic Slime, Rune-Scarred Demon, Sidisi, Brood Tyrant, -> get infinite mana and infinite tutors through my deck. Then I either get Altar of Dementia and Nezumi Graverobber to mill everyone out, or Melira, Sylvok Outcast and Woodfall Primus to blow up the board, or Gonti, Lord of Luxury to steal everyone else's entire remaining libraries.

What's yours?

January 28, 2017 1:56 p.m.

Whoops, that should be Sidisi, Undead Vizier. Not brood tyrant.

January 28, 2017 1:56 p.m.

Daedalus19876 says... #8

PhotogenicParasympathetic: Mine's in my I Call Her Vera: Sidisi EDH | *PRIMER* deck. It's a very modular combo (lots of interchangeable pieces) but the general thrust is something like:

(with a full graveyard) Victimize into Archaeomancer and Eternal Witness into Songs of the Damned and Yawgmoth's Will into Songs of the Damned (again) into Amulet of Vigor into Splendid Reclamation into cast everything from my entire graveyard onto the battlefield leading to any of my infinite-mill or infinite-damage combos.

The best thing about that combo is that I only need one of the pieces in hand (Victimize). Everything else can be milled into my graveyard.

Janky combos are the best combos. My actual main win-con in that deck is janky too: Altar of Dementia + Sidisi, Brood Tyrant + Selhoff Occultist + Dread (in my library).

January 28, 2017 2:05 p.m.

Janky combos are the only combos worth running. I like that last one a lot. Try tossing Undead Alchemist in for extra value!

January 28, 2017 2:12 p.m.

Daedalus19876 says... #10

PhotogenicParasympathetic: I'd love your opinion on that deck (I Call Her Vera: Sidisi EDH | *PRIMER*) if you have a chance :)

January 28, 2017 2:28 p.m.

shepherdofire says... #11

You need Urborg, Tomb of Yawgmoth if you are using coffers.

January 29, 2017 3:41 p.m.

kikexgaz says... #12

dude Consider contamination friend, I use my yahenni, this more grave titan, or Bitterblossom or other that generates tokens, it is combo if the other player does not play black

January 30, 2017 12:44 p.m.

Daedalus19876 says... #13

shepherdofire: While I definitely understand how good Urborg, Tomb of Yawgmoth is with Cabal Coffers, I'm not adding it for 3 reasons:

1) In mono-black, the improvement is marginal - almost all of my lands are swamps anyway so it rarely adds much.

2) I don't tend to buy $10+ cards unless I have a very good reason.

3) It makes it too easy for my opponents to mana fix, if they're playing black.

January 30, 2017 12:48 p.m.

Daedalus19876 says... #14

kikexgaz: I'm familiar with the card, but I don't run it on principle (I try not to lock people out of their mana sources). That being said, I agree it's a crazy good card, just not one I'm planning to use in this deck. Thanks for the comment anyway though! :)

January 30, 2017 12:50 p.m.

I may just be missing the Magical Christmas land scenario but can you please explain the combo: Walking Ballista+Yahenni, Undying Partisan+Mikaeus, the Unhallowed and how it can go off turn 3?

I'm Not trying to shoot it down honestly, as a fellow Yahenni player I need to know it works before I try and fib my way through it at a table :)

January 30, 2017 4:49 p.m.

Daedalus19876 says... #16

LittleBlueHero: No worries! I assume you see how the combo itself works - you can remove the counter from Walking Ballista to ping an opponent for one. It's a 1/1 (from Mikaeus) so it doesn't die, but you can sac it to Yahenni, Undying Partisan to "reset" its counter using Mikaeus, the Unhallowed. Rinse and repeat :)

There are two ways to achieve this by T3 that I'm currently aware of (I'm sure there's more somehow). First way:

T1: Swamp, Sol Ring, Walking Ballista set to X=1

T2: Swamp, Yahenni, Undying Partisan, one mana left to Vampiric Tutor for whatever you need.

T3: Lake of the Dead, sac a Swamp, cast Mikaeus, the Unhallowed, win.


T1: Swamp, Sol Ring, Jet Medallion

T2: Swamp, Yahenni, Undying Partisan, Walking Ballista at X=1

T3: Swamp, cast Mikaeus, the Unhallowed

Note that after you have Big Mike out, you can cast Walking Ballista at X=0 and the combo still works.

Happy deckbuilding! I'd love to look over your Yahenni deck :) And you're welcome to give a +1 if you like my deck!

January 30, 2017 5:52 p.m.

xyrithis says... #17

A card that I like with Yahenni is Worldslayer. It will basically reset the game, except you get to keep a massive Yahenni on the field.

January 31, 2017 11:24 a.m.

smitm901 says... #18

Maybe Genesis Chamber for the extra creatures for everyone? and why no lifelink giving effects like Basilisk Collar for the survivability?

January 31, 2017 12:26 p.m.

Daedalus19876 says... #19

xyrithis: That does sound powerful - Worldslayer is silly with indestructible creatures - but I never attack people's lands on principle. So I'm afraid it doesn't fit into my decks.

January 31, 2017 12:41 p.m.

Daedalus19876 says... #20

smitm901: Honestly, I just find that the lifelink isn't generally relevant, given the frequency of infinite combos in EDH. Whip of Erebos is helpful for offsetting my own life-loss effects, though (and useful beyond that).

January 31, 2017 12:42 p.m.

ggodo says... #21

I really like this deck. Weird suggestion: Mephidross Vampire. It plays well with the counters theme you've got going, though it's a bit expensive.

February 1, 2017 12:05 a.m.

Daedalus19876 says... #22

ggodo: I'm glad you like the deck! :) You're welcome to leave a +1 if you want.

Mephidross Vampire is an interesting idea! I've considered putting both that and Necropolis Regent in this deck. I haven't found slots yet, though...

February 1, 2017 12:46 a.m.

ggodo says... #23

It's hard to find room for the big expensive stuff. My wife runs Mephidross in her Olivia Volderen deck, and it does some serious work with her ping ability. Olivia gets big fast.

GobboE says... #24

Ahh, my hands started itching when I saw this deck: it look like so much fun!

Crypt Rats found a place in this deck...that alone warrants a +1 :)

I really like the balanced approach you took, so with some fear that I will unbalance it all, here are some quick suggestions:

  1. Contagion Clasp or its bigger brother Contagion Engine: destroys one of your opponents creatures if your lucky, and multiplies any counters you wish. Perhaps instead of Key to the City, personally I am not such a big fan of that card.

  2. I have to mention her, she fits your deck so good...but I reckon the high cmc is keeping you playing her: Sheoldred, Whispering One, and has nice synergy with your commander. Perhaps instead of Tombstone Stairwell? Since the Tombstone also gives tokes to your opponents, and they might benefit from it.

  3. Burnished Hart: ramp, sacrifice and a creature all rolled into one. If you play multiplayer, I would take out Curse of Shallow Graves, since it benefits your opponents too and could work against you

February 1, 2017 2:42 p.m.

Daedalus19876 says... #25

GobboE: I'm glad you like the deck! I'm also happy I could use Crypt Rats - they're one of my pet cards and I finally found a deck that supports them extremely well. I'm trying to decide which art to use for them, though...And in answer to your questions:

I'm actually running Contagion Engine in my list IRL right now. It's definitely pulling its weight at the moment, and I need to find a slot for it. I do like Key to the City a lot, though...I'll definitely consider this more.

Yeah, Sheoldred, Whispering One is kept out of this list because of the high cost (both in terms of dollars and in terms of mana). I'll add a copy if I can get my hands on one. Tombstone Stairwell is one the key cards in the deck, though - Yahenni easily becomes a 30/30 in a single turn cycle, and it gives me basically unlimited sac fodder: I can profit off of the death triggers better than my opponents can.

I tried Burnished Hart in this list, and it just wasn't a fit, alas. 6 mana to fetch two lands wasn't worth it, especially since I couldn't sacrifice it to Yahenni and still get the lands. Solemn Simulacrum went in that slot instead.

Thanks for the comment! If you have any other thoughts on changes I could make I'd always appreciate them :)

February 1, 2017 3:10 p.m.

GobboE says... #26

@ Daedalus19876 : You are welcome. Yes, I see how Tombstone Stairwell fits your deck. As you wrote, with Eldrazi Monument, it is very powerful. And you run Consume the Meek to get rid of opponent's tokens.

Oh I really love this deck :)

One last thing, if I may because I am really interested in why you have , and have not, considered certain cards, such as Languish. Additional creature destruction (particularly one that gives -4/-4) weakens your opponents while it strenghtens you. Why have you decided not to run it?

February 2, 2017 3:43 a.m.

Daedalus19876 says... #27

GobboE: To be honest, I've been trying to avoid -X/-X board wipes because they bypass the indestructibility on my commander and granted by Eldrazi Monument. They also fail to kill large creatures, which is a big deal when one of the most scary decks in my meta is an Ezuri deck. Accordingly, the only -X/-X board wipes in the deck are Toxic Deluge (just too good to avoid, and I can "tune" it to miss my commander many times), Decree of Pain's cycling (I have the option to use the full-strength version instead), and Yahenni's Expertise (great value and too much flavor to exclude).

I hope that answers your question about why Languish (and Mutilate) aren't in the deck! :)

ThinkJank says... #29

Congratulations on a hundred upvotes! I really love what you've done with this deck. I hadn't even heard of Tombstone Stairwell before now, but I'm amazed at how cleanly it fits with the deck's strategy. I would offer a suggestion, but this deck looks pretty much perfect.

February 2, 2017 7:44 p.m.

needs more token generators

February 3, 2017 11:25 a.m.

Daedalus19876 says... #31

ThinkJank: Thank you for your comment anyway! :) And yes, Tombstone Stairwell is one of the forgotten gems of magic. I just wish it didn't have that pesky cumulatively upkeep cost...

feyn_do_alduin: As far as I know, I'm already playing all the decent ones in black (minus Bitterblossom, because I don't own a copy). Are there any I'm missing? Black isn't known for its tokens.

February 3, 2017 12:03 p.m.

in black, you have all the great ones. but have you considered; Soul Foundry, Pentavus, or Myr Battlesphere?

Soul Foundry seems like it has a place in the deck because it can combo with almost all of your creature spells

February 3, 2017 12:17 p.m.

Daedalus19876 says... #33

feyn_do_alduin: I'll pass on Pentavus and Myr Battlesphere (way too much mana investment for their effect) but I might be able to find a slot for Soul Foundry...Thanks!

February 3, 2017 12:33 p.m.

Springfluter says... #34

Please help me: Walking Ballista can shoot its +1/+1 counter. Mikaeus, the Unhallowed can bring it back with aditional +1/+1 - but these aren't counters, the ballista can't shoot. Am I right?

The only thing the Walking Ballista can be for you is a reusable sac out for Yahenni, Undying Partisan

I like what you have done with Yahenni, I tried to build her too but ended up doing nothing in a multiplayer game. Have a look if you want to.

February 10, 2017 4:31 a.m.
  1. Remove all counters from Walking Ballista to unload on some poor sap. Ballista remains as a 1/1 thanks to Mikaeus, the Unhallowed.

  2. Sacrifice your 1/1 ballista to Yahenni, Undying Partisan. It will return to the battlefield via mikaeus with a +1/+1 counter on it.

  3. Remove that counter to ping what have you. Ballista is back to being a 1/1 with no counters.

  4. Sacrifice ballista to yahenni... rinse and repeat until you have pinged everthing and everyone into oblivion.

February 10, 2017 9:37 a.m.

Springfluter says... #36

Got it, forgot the undying. Thank you.

February 10, 2017 9:45 a.m.

No problem,

You have no idea how many times someone has mentioned an awesome combo that I have stared at for longer than I would like to admit before eventually just giving up and asking.

Thats what the community is for!

Great deck!

February 12, 2017 8:19 a.m.

Hades_Shadow says... #39

To help Yahenni grow bigger, I would add Necropolis Regent to double his power every hit. It also pumps thing like Hangarback walker before you sac them for more creatures.

February 14, 2017 10:10 a.m.

Daedalus19876 says... #40

Hipparchos: Thanks! :)

Hades_Shadow: I'll consider it! Just not sure what to cut...

February 15, 2017 2:49 a.m.

Dark Depths + Vampire Hexmage here Magit Lage

February 15, 2017 9:45 p.m.

maxeh34 says... #42

also Triskelion

February 15, 2017 9:52 p.m.

Daedalus19876 says... #43

maxeh34: I think I'll pass for now. I don't have the slots, and neither is good without the other. HOWEVER, the equivalent combo Dark Depths+Thespian's Stage is going into my Omnath deck to be fetched with Tempt with Discovery ;)

And in my case, Walking Ballista is a strict upgrade over Triskelion.

February 15, 2017 10:04 p.m.

maxeh34 says... #44

what reanimation spells do you use and what tutors are there

February 15, 2017 10:19 p.m.

maxeh34 says... #45

maybe run Liliana, Heretical Healer  Flip for returning sacs and creatures you kill

February 15, 2017 10:25 p.m.

Daedalus19876 says... #46

maxeh34: I've now updated the deck, so you can see my reanimation and tutors. I'll consider Liliana, Heretical Healer  Flip - while I cut her from my original draft, I think that later additions might make her more powerful than in the earlier incarnations of the deck.

Thanks for your comment! :)

February 16, 2017 1:47 a.m.

Entrei says... #47

You are missing some of the explosive mana black is famous for, mostly stuff like Nirkana Revenant, Caged Sun, Gauntlet of Power, Cabal Ritual and maybe Doubling Cube if you really wanna go hardcore mana. Good list tho :)

February 16, 2017 9:56 p.m.

Daedalus19876 says... #48

Entrei: Interestingly, I used to include more of those, but I often ended up with too much mana and too few things to do with it, haha. I'll take it into consideration, though! :)

February 16, 2017 10:21 p.m.

TearsInRain23 says... #49

A solid deck. Looks like you could use some more ways of generating extra mana. Maybe Crypt of Agadeem, or Magus of the Coffers, or even Nirkana Revenant could find a home here.

Sorry for the late feedback I have been busy. My white/ black deck has seem some substantial upgrades if you're interested.

February 20, 2017 9:17 p.m.

acefalo says... #50

I love Yahenni.

I love Monoblack decks.


I read the cards and suggestions, obviously Waste Not would do much unless accompanied with a discard outlet. That being said I would pair it with Liliana, Heretical Healer  Flip.

I really think Hatred is a must (I see it in the Maybeboard).

Nice deck!

March 3, 2017 9:59 a.m.

acefalo says... #51

I just realized that you don't have a Kalitas, Traitor of Ghet in the deck! Nuff said

March 3, 2017 1:39 p.m.

Daedalus19876 says... #52

acefalo: Thanks for your interest! :) Yahenni is awesome, definitely my favorite mono-black deck that I've tried constructing.

I'm trying to decide if I should include Liliana, Heretical Healer  Flip. I've also made a few changes to this list that I need to update.

I need to get my hands on a copy of Hatred...

However, I'm not a fan of Kalitas, Traitor of Ghet here. His replacement effect means Yahenni can no longer get counters :(

March 3, 2017 1:45 p.m.

acefalo says... #53

Owwwwww.... I failed to read/remember the "instead" part... my bad!

Another thing I recalled: Reconsider putting Urborg, Tomb of Yawgmoth. I ran a mono-black casual deck that uses all four Cabal Coffers, Urborg, Tomb of Yawgmoth, Lake of the Dead and Ancient Tomb. It fixes Ancient Tomb as a swamp for Cabal Coffers and eventual fodder for Lake of the Dead and fixes Cabal Coffers itself: when you have a 3 land draw with a Cabal Coffers, you pray the Gods for another Swamp to come so I won't manascrew myself. A turn 3 Cabal Coffers you won't cast Yehenni unless you have that Urborg, Tomb of Yawgmoth (mana rocks aside).

PS: Ancient Tomb

PSS: I also ran City of Traitors but those are quite pricey now

th@Puppr says... #56

So you got yer Grave Pact and yer Dictate of Erebos, but what about
Butcher of Malakir ?

Sure he's a bit more mana-expensive, but Grave Pact is probably the strongest effect in the deck, so why not 3 of them for extra "well this isn't fun anymore".

Also Butcher can hit em for flying AND you can sac him to Yahenni in a pinch. Plus, he's cheap! Monetarily speaking.

March 16, 2017 2:22 a.m.

Daedalus19876 says... #57

th@Puppr: He just eats my board wipes too easily shrug And 7 mana is a LOT. For that much mana, I could just play Sheoldred, Whispering One instead.

March 24, 2017 1:43 p.m.

enpc says... #58

Dark Ritual is awesome, let's you get a turn 1 Yahenni. Also Forbidden Orchard could be fun in that you can forcefeed your opponents creatures to sacrifice if they don't have any. And you seem to have enough ways to plow through tokens.

March 28, 2017 1:14 a.m.

WillySmasher says... #59

I know you already have a lot of sac but have you considered Ashnod's Altar for mana ramp and an additional sac outlet to trigger Grave Pact or do you feed them all to Yahenni? Also +1 for Forbidden Orchard.

I was going to make a Ghoulcaller Gisa zombie tribal but this might replace my mono-black deck slot, +1!

March 28, 2017 2:51 p.m.

Daedalus19876 says... #60

WillySmasher: Thanks for the comment and upvote! :) I'll definitely consider Ashnod's Altar, it's just getting pretty hard to find cuts for the deck haha.

I actually used to be running Forbidden Orchard in here, but I had to move my last copy to my Animar, Soul of Elements deck for mana-fixing reasons. Still, I need to get another copy for this deck :)

March 28, 2017 2:55 p.m.

Burgdawg says... #61

Inquisition of Kozilek and Thoughtseize let you rip things from people's hands if it's control you're seeking.

I see you're running Helm of Obedience and not TOO much recursion... I might add in Leyline of the Void to hose zombies and other recursion decks, and it also combos with Helm of Obedience to instantly mill a library.

Temporal Extortion always makes people consider 20 life... or give black control another turn.

Sudden Spoiling for pesky creature abilities maybe?


March 29, 2017 4:01 p.m.

Daedalus19876 says... #62

Burgdawg: I'll pass on the discard, I think - Thoughtseize could be good, but it doesn't synergize well with the rest of the deck.

I'm not running Helm of Obedience, I'm running Helm of Possession ;)

I have a copy of Temporal Extortion right here, I'm just not sure if it fits here. Thoughts? If you think it's worth including, what would you cut?

Thanks for the comment and +1! :)

April 12, 2017 6:08 p.m.

Burgdawg says... #63

Oh yea, I musta been tired when I made that comment, this helm, that helm...I'd only play Temporal Extortion if you like the flavor. If your plan is to win via commander damage there's no upside to someone paying life. Early game it's always good because it cost someone 20ish life to counter, and if they don't you get extra set up. Late game no one will likely give you another attack.

Cenzino says... #64

How can i make this deck for duel commander?

April 28, 2017 8:47 a.m.

Daedalus19876 says... #65

Cenzino: I'm sorry, I missed your comment! As far as I'm aware, the only thing on this list banned in Duel Commander is Sol Ring. I'd just cut Sol Ring (maybe for Contamination?) and it's legal.

However, this deck has a pretty high mana curve for Duel Commander. I'd cut at least some of the high-mana cards for other, cheaper options. No use having something in hand if you can't play it before you die.
