Altar of Dementia


Sacrifice a creature: Target player mills cards equal to the sacrificed creature's power. (To mill a card, put the top card of your library into your graveyard.)

wallisface I swapped out a bunch of creatures that were inefficient from a sacrifice standpoint and made some other changes. I learned about persist loops & milling via Altar of Dementia, but that feels like a less fun win condition to me compared against persist looping direct player damage or pumping my creatures.

I noticed that I kinda made a hole in my mana curve at 3 mana. Is this important? Any other ideas for improvements from here? Thanks again as always!

Brilliant! I've always thought Enduring Renewal needed more representation in modern. This sort of goes against the spirit (or the bats) of the deck, but someone decided Altar of Dementia should be modern legal, so that could be an effective alternate win condition.

Love the combo of this deck!

I've been tinkering with a zombie sacrifice deck myself and I got a few recommendations that might be helpful:

Ayara, First of Locthwain could probably be replaced with Blood Artist or Zulaport Cutthroat (the later being slightly worse, but also cheaper to buy irl). They all do functionally pretty much the same, but Ayara is more expensive with her 3 mana cost. So you might as well replace her unless you absolutely feel like you need that option to sac for her card draw or might have a reason to prefer the damage on creatures entering the battlefield rather than dying.

Headless Rider honestly doesn't feel like it's doing very much in this deck. As far as I understand it, the main wincons are either dealing damage through Ayara's ability or milling via the Altar of Dementia. Creating tokens just feels unnecessary and having more draw to get to your combo pieces faster is probably more useful. For example, Village Rites combos well with having disposable creatures and Undead Augur, effectively allowing you to draw 3 cards for 1 mana at instant speed.

If you don't mind your removal being sorcery speed, then you might want to give Bone Shards a try. It gives flexibility in either discarding or sacrificing for its cost and can also target plainswalkers. Finally, maybe 1 or 2 copies of Unearth could be useful as a failsafe in case important combo pieces end up in the graveyard. It can get you literally any creature from your deck back and that for just 1 mana.

I forgot to mention above that I replaced the three "demigod auras" with Altar of Dementia, Golgari Germination, and Ravenous Squirrel, since those cards better fit the theme of this deck.

I have replaced Favor of the Overbeing, Gift of the Deity, and Helm of the Ghastlord, which decreased the average converted mana cost of this deck from 3.85 to 3.82, which is very nice, since those cards better match the theme of this deck; in particular, Altar of Dementia gives me an additional way to put creatures into my graveyard and also make my opponents put creatures into their own graveyards, for The Mimeoplasm to copy.

I like the cards you have here! Great stuff so far. I have several questions and suggestions:

  • I know these are the cards you have on hand, but is money a factor so far as buying additional cards? If not, I would highly recommend a Tendershoot Dryad. It will pair well with your Sporecrown Thallid, Verdeloth the Ancient, Nemata, Grove Guardian and Verdant Force. These cards are a pretty solid core for the deck. Now start looking for ways to tutor them. Worldly Tutor, Diabolic Intent, Grim Tutor..... we are in fantastic colors for tutoring the cards you need.
  • After building the core of your deck and what you want it to do, I like to add support and utility cards. I love Viconia, Drow Apostle, Shadowheart, Dark Justiciar, Rankle, Master of Pranks, and Loyal Guardian for this purpose! Might I recommend a Thunderfoot Baloth to pair with your Guardian?
  • Cut your land count down to 37 - 40, then playtest and see how it feels
  • Play to your commander's strength. I am working on a budget version (less than $80) of The Mycotyrant myself, and will be playing Cemetery Tampering, Crawling Infestation, and Crawling Sensation. One of the things I try to do is build a deck that functions well without the commander on the board so I am not completely hosed when they are removed. I like all 3 of these enchantments because I am not in danger of decking myself, and if the commander is not on the field I do not have to mill. I talk about milling, because it plays to The Mycotyrant's strength as a commander. We will see if I still want all 3 enchantments in the deck after I build it and see it in action, hopefully soon.
  • If you decide to lean into milling yourself and sacrificing creatures like I have for my deck, I would recommend stepping away from non-creature spells and do your removal in creature form. I currently only have a total of 7 sorceries and instants in my deck, so as I mill myself I am more guaranteed to hit permanent cards. Remember that The Mycotyrant cares about permanent cards in your graveyard, so sacrificing your tokens will not contribute to its descend mechanic.
  • To follow along the vein of previous suggestion, invest in some free sac outlets: Greater Good, Altar of Dementia (target yourself to capitalize on commander ability at your end step)

I think that's all I have for the moment...... let me know if you have any questions! Here is my work in progress Budget Mycotyrant

Of note, I haven't play the Souls of the Lost with Ob Nixilis, the Adversary. You can literally have a turn 3 15 point swing... and if you can get an attack in first, GG.

You can also aim for alt-wins. Altar of Dementia. And with The Skullspore Nexus you can sac a goyf to Altar, you or opp mill 10. Get a 10/10 dino fungus and mill for another 10. You can play for your own self-mill win with Thassa's Oracle or Laboratory Maniac.

There is a lot of gy hate and I always play with one or the other side for alt-win.

I'm also considering maindeck Leyline of the Void because so much of magic these days are graveyard based.

Made_Compleat on Actual Literal Biblical Satan

Wow, this is a really cool deck! It certainly looks like fun abusing Actual Literal Biblical Satan.

I have one small suggestion. Hell's Caretaker doesn't really work here, as you can only use it on your upkeep. This means that Act of Treason effects don't let you sacrifice the creatures you steal to the Caretaker. I'd recommend cutting it for one of the following: Altar of Dementia, Woe Strider, or Viscera Seer. All of these are free sac outlets you can use whenever.

Again, I love the deck! I have a similar deck that I play a lot, Memnarch's Eleven. It's a similar theme but mono-U instead of rakdos. I'd love it if you could check it out and maybe make a few suggestions. Thanks so much!
