Altar of Dementia

Artifact

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.)

I have replaced Fists of the Demigod with Altar of Dementia, as the latter cards gives this deck both an additional sacrifice outlet and an additional way to put creature cards into my opponents' graveyards, for me to steal with Tariel.

DemonDragonJ on Should I Put Altar of …

1 week ago

I am contemplating putting a copy of Altar of Dementia into my Tariel, Reckoner of Souls EDH deck, likely replacing either Searing Meditation or possibly Fists of the Demigod, but I wish to ask the other users here for advice, before I do that.

Since that deck focuses on stealing my opponents' creatures for both combat and sacrificing, AoD would provide both an additional sacrifice outlet and an additional way to put creature cards into my opponents' graveyard, for me to steal, which is obviously a good thing.

What does everyone else say about this? Should I put Altar of Dementia into my Tariel deck?

I really appreciate all the Feed back, I know the synergy needs work but at that point I might as well copy someone’s deck. The goal is to ramp the artifacts help always tutor for Nyxbloom Ancient and then Doubling Cube becomes 3x more effective. Lithoform Engine can copy that effect and compile it more so, often creating well into the hundreds of mama, so 4 cost to draw a card with Diviner's Wand something I can repeat as I want is negligible. At that point you get to a card where you get a card that allows you to place majority of your deck into your hand and do mostly as you please. Along with that Genesis Wave places all the land and permanents you need and usually by turn 5 there’s enough mana that it’s worth the drop setting the following turn up for huge mana and usually can end game sacing omnath to Altar of Dementia or just simply attacking. Or even Squall Line

Still plenty of play testing needed, but this also isn’t a full on competitive build just for my play group. I will definitely take a deeper look and playtest some of the changes.

I have replaced Glory of Warfare with Feast of the Victorious Dead, which decreased this deck's average converted mana cost from 3.87 to 3.84, since the latter card better fits the theme of the deck than did the former card, in my mind.

Should I put Altar of Dementia into this deck? That would give this deck an additional sacrifice outlet, and also put more cards into my opponents' graveyards, for me to steal with Tariel.

I leave this in your capable hands. Do you think the deck needs more removal? Sadistic Hypnotist or Feed the Swarm. Another win condition? Altar of the Brood, Altar of Dementia, or Karumonix, the Rat King. More card draw? Phyrexian Arena, Black Market Connections, Deadly Dispute, Bankrupt in Blood, or Village Rites. (I know I suggested some of these cards already; they've worked well for me.)

GhostmkakerQQ on Current Zombie Deck (needs work)

I have removed the following cards:

Curse of the Restless Dead

Blade of Selves

Mystic Skull  Flip

Crawl from the Cellar

Altar of Dementia

Ghouls' Night Out

Pyre of Heroes

Liliana's Mastery

Added a few cheap zombie cards in as well as more land cards as advised by Lukas96. this has drastically improved the deck in performance thank you! I usually win by turn 12 or earlier (testing on Ai of course).

I will continue to improve the deck.

Added Kairi, the Swirling Sky to the deck, so added a combo around her. Still haven't won with the combo, though, it's too convoluted and unwieldy to pull off easily: Turnabout for mana advantage, Altar of Dementia, and Stitch Together to repeat until everyone has milled out and I will have infinite mana with access to all of my instants and sorceries, e.g. Dredge the Mire

In my Meren deck, I don't run a lot of bigger creatures, even though the deck has decent odds of ending up with huge amounts of mana, stuff like Beast Whisperer/Grim Haruspex draw cards off of creatures either entering or leaving the battlefield, there are lots of variants of both of those effects, and these will let you play many spells in a turn, rather than play one huge thing. I don't think your MVs are a huge problem, but the 'top of my curve' creatures are Razaketh, the Foulblooded, Protean Hulk, and Sheoldred, Whispering One, the first two can win on the spot or very quickly, while Sheoldred is a bit more questionable, a lot of people find stuff like Sheoldred tends to be too slow in todays game, so even that is a card I'm considering switching out for lower to the ground stuff. I checked and atm I have 14 1 drops, which is a few more, there are plenty of decent 1 drop mana dorks you could throw in to both lower your curve and possibly raise your consistency, though the best is Elves of Deep Shadow, since your deck cares more about Black mana.

As a general rule of thumb for Meren, if you can do a thing with a creature instead, you probably should unless the creature option is truly awful, I run 55 creatures in the 99, and I'm still thinking about sneaking more in by taking out things like Artifacts. Creature payoffs are better than artifact payoffs in Golgari, and Meren can't recur non-creatures.

For sac outlets, you ideally want a selection of 'free' sac outlets, ones that only use a creature and no other input, so stuff like Viscera Seer, Carrion Feeder, Woe Strider, any of the good altars (Phyrexian Altar, Ashnod's Altar, and Altar of Dementia are my all very good), Sadistic Hypnotist is insanely useful (it is a 5 drop though), if you have 4 drops that matter you can use Dimir House Guard because Transmute is a good mechanic if you care about the MV and it's also a free sac outlet. I think you can throw in a few sac outlets that are more limited, stuff like Helm of Possession, Phyrexian Tower, Hell's Caretaker, Altar of Bhaal, and Ritual of the Machine are all beefy effects, even if you can only use them once per turn. I really like stuff like Sakura Tribe Elder because the card provides it's own sac outlet (but only for itself), ymmv but I think you're taking a risk by running something like Solemn Simulacrum over Dawntreader Elk or Diligent Farmhand, 4 mana is a ton and it lacks a self destruct feature.

One option some people end up taking is replacing Meren as the Commander, not because she isn't strong enough but because the play patterns are pretty consistent, once you've figured out what your deck is trying to do, Meren is usually very predictable, so some people prefer something like Baba Lysaga, Night Witch. She offers card draw and a sac outlet in the Command zone while caring a lot less about creatures in particular, so you'd have more freedom in terms of card types.

Hope some of this is helpful!
