Altar of Dementia Discussion

cassa on Teysa, Orzhov Scion

Hi, thank you for your advices, they're precisely what i needed! First of all i know that the description is rough and approximate, when i'll arrive to 100 cards beeing sure i'll fix it once for all.

I didn't consider Victimize , but it's perfect for this deck: I'll add immediately. Same for Razaketh, the Foulblooded that i own and Altar of Dementia .

Fetid Heath , Phyrexian Tower and Diabolic Intent are surely better, and are in my wishlist for now, but i'm already investing in my Kaalia deck and except for some budget utilities (like Wake the Dead ) i prefer to wait.

Talking about the cutting (that was my biggest problem):

Hey, nice version of Teysa. In the deck description you've left out three of the most relevant infinite sac combos that use the least amount of cards. My advice is to focus on the easier winning combos to assemble especially ones that use Teysa as part of the combo.

  • Teysa + Hour + Black Creature + Aristocrat
  • Teysa + Guide + Lark + Aristocrat
  • Teysa + Traitor + Altar + Aristocrat
  • Teysa + Skeleton + Altar + Aristocrat
  • Warder + Animate + Aristocrat
  • Guide + Lark + Station
  • Guide + Lark + Dementia

Teysa + Guide + Lark + Aristocrat: Teysa is a white creature who can be saced to her own ability and Lark can reanimate Teysa since she has 2 power. Teysa + Guide + Lark equals three white creatures. Victimize is an excellent card to enable this combo by using Teysa to sac to reanimate both Lark + Guide and then reanimate Teysa with Guide.

Warder + Animate + Aristocrat: You have these cards in the decklist, but haven't explained the combo in the description. It's one of the most compact, low mana cost aristocrat combos in Commander. Razaketh, the Foulblooded is the creature of choice to enable this combo since he can tutor for all the cards and get Warder into your graveyard. With Razaketh this combo is called RazaCats. If you would like me to explain it further I can.

Guide + Lark + Station: Station acts as the aristocrat and the sac outlet in this combo which reduces it by two cards.

Guide + Lark + Dementia: Altar of Dementia is the sac outlet to infinite mill your opponents libraries. It's a win condition without needing to do damage or make your opponents lose life. It can also be a self-mill engine to fuel reanimation. Self-mill all your 2 or less power creatures and reanimate them all with Lark.

Cards to consider cutting:

  • Elenda, the Dusk Rose
  • Pitiless Plunderer
  • Teysa Karlov
  • Restoration Angel
  • Felidar Guardian
  • Cathodion
  • Requiem Angel
  • Geist-Honored Monk

Your deck is loaded with four drops and these are the ones that are the least impactful. Angel + Guardian is infinite Angels, but these two cards don't really fit with the rest of the deck and I don't like that Angel can't be reanimated with Lark. Autocrat can replace Monk in all the combos therefore I don't think you need Monk since it's a five drop and both Guide and Lark are better five drops.

Teysa Karlov and cards that have more synergy with her can be cut because you don't need her ability of giving you additional die effects. This can be fine when you have access to it from the Command Zone, but it's lackluster as just part of the rest of the deck. Your deck is about combos, with Teysa as Commander you don't need Teysa Karlov's ability to combo, it's a bonus.

Some cards within the budget to consider adding:

I offer more advice if you would like. Good luck with your deck.

I'm not sure if you're already aware of this, but Ankle Shanker doesn't work with Alesha's ability because he already comes tapped and attacking, while his trigger happens during it's attack declaration. Ignition Team is one I really like in my Alesha deck, he usually enters as a very big beater and when reanimated with Alesha can be deadly. Altar of Dementia , Spawning Pit , Ashnod's Altar . Alesha really smiles at death, so having those sac outlets will be the best way to get the most value out of recurring creatures with your commander. Plus it's an essential enabler if you wish to combo off with Karmic Guide + Reveillark or Anafenza, Kin-Tree Spirit + Murderous Redcap .

Very interesting concept! I love the idea of group hug theft! Have you thought of including sacrifice outlets like Ashnod's Altar or Altar of Dementia ? Seems like it could be a new win condition in case someone tries to gain control of their permanents or remove Rubinia? +1 for creativity!

Thanks, Esperkyde! I'm glad you like it. I'm actually trying to find room for a few cards: Altar of Dementia , Bontu's Monument , and possibly Lord of the Accursed . Any suggestions? And thanks for the upvote!

What do you think about a second bloom tender -> Faeburrow Elder ? Maybe for Eldrazi Displacer because the „c“ in his ability cost is really hard to loop with. Do you thought about sacrifice outlets Bloom Tender + Altar of Dementia + Dervi you win the Game. Here is my deck maybe you finde something -> Straight outta combo (Derevi-Commander)

I've dug up my old Zombie tribal deck, and am looking to make some changes:


Commander / EDH bushido_man96


I've made some changes to the mana base already, and I've got a few cards I want to add to make it more combo-esque. I'd like to slot in Altar of Dementia , Bontu's Monument , and possibly Lord of the Accursed . Suggestions on what to swap would be great, and so would upvotes!
