ZendikariWol I'm glad I was able to help. It looks like you made a nice list!

Last_Laugh The rat boy is in my maybeboard, but I'm not sure if I like him better than any of the token producers I'm using at the moment, so he doesn't have a slot in the deck. He's definitely a powerful card with Teysa though.

I couldn't help but notice that you didn't put Sheoldred, Whispering One or Demonlord Belzenlok in either your mainboard or maybeboard

literaturecult46 Sheoldred definitely should have a home in some lists that want heavy bombs. Belzenlok wouldn't fit my specific build however due to my low mana cost, but I can see running him in higher average cmc lists. I'll add both to the maybeboard.

Have you thought of Secure the Wastes over Martial Coup ? Or has the board wipe effect edged it out?

FutureWitness Secure the Wastes is viable, but Martial Coup 's versatility and ability to wipe the board is definitely useful, especially in a deck that cares about its own creatures dying. I'm also playing it over other board wipes such as Merciless Eviction , Cleansing Nova , Fumigate , and Wrath of God just for its ability to make tokens.

People are saying that Teysa Karlov is more of a card that belongs in the 99 more than as a standalone commander, I think that her death Panharmonicon effect warrants her being a commander. Have you found her to be under powered compared to most decks(If you have done any play testing)?

what about Lightning Coils

FutureWitness I have seen many people saying she belongs in the 99 as well. The main point in favor of this is that Teysa Karlov doesn't provide any of the pieces to an aristocrats deck herself. In comparison, other commanders like Teysa, Orzhov Scion or Krav, the Unredeemed and Regna, the Redeemer provide tokens and sac outlets by themselves. This means Teysa Karlov has overall less consistency; however, she provides other valuable aspects to the strategy.

You mentioned her necronomicon effect which allows for incredible value. With the other commanders, it will be easier to get an engine going since they provide some parts, but with TK, the engine will be much more powerful. Ultimately it comes down to preference. What you've been seeing are the people that prefer consistency over power, and there is validity to that. I would say competitively, the consistency wins out. Though, in my opinion, new Teysa's ability to copy death triggers is something I definitely want in my command zone.

In the testing I've done so far, the deck has been far from under-powered, but that depends on many factors such as meta and power level. My meta is 75%, but if yours is 90%, this deck would definitely be lacking. Inversely, in a heavily casual 30-40% meta, this deck would stomp.

As for whether or not she should be your commander, its up to you. Her effectiveness as a commander is apparent, and unless you're playing in a super competitive meta, she'll do great.

willis1234 Coils is cool. It makes the death engine run a lot faster and provides a lot of tokens with Requiem Angel . However, it's very slow to get running and does nothing until the engine is online. I'll add it to the maybeboard.

wouldn't Ghoulcaller Gisa be really good in this deck?

A little surprised not so see Seraph of the Scales here. She seems powerful enough, and the flavor would be on point.

Other interesting options would be Dead Man's Chest , Desperate Sentry , Yahenni, Undying Partisan , and Overseer of the Damned .

willis1234 She certainly wouldn't be bad in the deck. However, for token producers, I'd rather them be death triggers to combo with Teysa. There's also the benefit of cards like Requiem Angel working immediately if I have a board presence plus sac outlet while Gisa is a bit slower.

CaptSillva Seraph has synergy, good flavor, and beautiful art, but I'm not sure it does enough for the deck to justify its cost. The only part I care about is the tokens, and there are better or cheaper producers. A 4/3 flier than can give itself deathtouch and vigilence isn't bad, it just doesn't work towards our gameplan. Though in other decks I can see why it would be played.

Dead Man's Chest is weird. It's card draw from an opponent's deck that also requires us to kill their creature. In the ideal scenario, we'll draw like 8 to 16 cards off of it. However, none of those cards will be working toward our death engine, we'll need to spend a removal spell on the creature most likely, and many of our removal spells exile instead of kill. With a more control heavy deck, I'd be more inclined to play this.

Desperate Sentry is ok. I value more tokens over big tokens, so I would rather play Ministrant of Obligation .

Yahenni, Undying Partisan is a good sac outlet that seconds as a moderate threat, but I personally don't care about the threat part much, so I'd rather play other sac outlets. If a free sac outlet is needed, I see its usefulness.

Overseer of the Damned is very powerful. If the deck ever needs more of a top-end (which it honestly might atm) I would consider playing this.

I'm going to add all of these cards to the maybeboard since they're all good suggestions.

You have quite a few important enchantments how about adding Academy Rector as a rattlesnake against early aggression and an efficient tutor especially with a sac outlet to improve consistency?

I like the idea of having Wound Reflection to lower the treshold needed for a torment or blood artist kill (fetchable with rector). Revival / Revenge can improve the deck's resilience while giving another wincon with wound reflection.

I am also curious to your thoughts on if Debt to the Deathless be a better Exsanguinate type effect than Torment of Hailfire ?

ThaneGarrus Academy Rector is a good card even though it doesn't combo with Teysa, but I'm not sure I have an open slot for her at the moment. Wound Reflection falls under the same slot problem. If I included one I would probably include the other. Revival/Revenge is good and versatile, but each of its effects individually are a bit lacking. The versatility might be worth it though.

Debt to the Deathless is better than Exsanguinate, but the real reason I include Torment of Hailfire is for its early potential. Debt and exsanguinate are not great when cast for even 7 or 10 mana. Hailfire can get rid of cards or deal even more damage when cast for that much. In a deck that needs a huge mana payoff, I'd play all three, but since this deck isn't focusing on that, I'm just playing the more versatile one.
