Altar of Dementia Discussion

RNR_Gaming Once people step away from the Merfolk and Zombies and whatever, all the big tribes, it becomes more interesting. I've seen a couple variations of Spider tribal and Golem tribal, I'm always working on Skeletons, and I hear Omniscience_is_life built a Dryad deck.

If even that feels too repetitive, mess with the colors or themes. Try Boros Dragons, or Grixis Elementals. Outside of Commander, Slivers can be almost any color combination and focus, if you stick to 1-3 colors. Altar of Dementia , Sands of Delirium , and Altar of the Brood take the ramp and token spam of an Elf deck and turn it into a mill deck.

Every few years, a tribe gets a big push--Treefolk in Lorwyn, Vampires in Zendikar and Innistrad, Pirates and Dinosaurs in Ixalan, Knights in Eldraine. Even without those, most tribes have some sort of internal synergy or theme. These might not break a Top 8 or whatever the measurement of success is these days, but they'll be more memorable than Orzhov Stoneblade #5427.

So, is Grist, the Hunger Tide a constant creature? Like, if you sacrifice it is the insect still be there? I'm probably misreading or misunderstanding the card but if it worked like that he'd be abundant sacrifice fodder and would open up a lot of cool lines with Altar of Dementia

Fantastic stuff going on here. Really clever interactions with Altar of Dementia !

Hmmmm. Ok, i’ve got a couple suggestions, but feel free to let me know if i’m off base on any of them:

Genesis Wave seems lackluster; you spend a lot of mana to get a bunch of permanents but none of them count towards your storm count. Could be dropped for Noxious Revival for additional graveyard recurral and hate in one piece. Slap a Geier Reach Sanitarium in place of a forest and you have all the pieces for an alternative win con, in the mill line that’s used in Yeva Draw-Grow. Mikokoro, Center of the Sea is an option as well, but you need a discard outlet to not deck yourself too, if i’m not mistaken.

Genesis Hydra is cool to dig for a combo piece if you have infinite mana, but it seems like if you have infinite mana you may as well produce infinite storm, drop Aeve, and win. I think Altar of Dementia is a good win con in this deck for that reason.

Karametra's Acolyte could probably be swapped for Priest of Titania . I think you have enough elves for them to perform similarly, and priest is cheaper.

Only other thing i can think of, is that some of your draw is either slow, or over costed, and could possibly be replaced with more abusable options. Toski, Bearer of Secrets , Rishkar's Expertise , and Elemental Bond are the main ones i’m referring to. If you have infinite storm Bond is gonna deck you when/if you cast Aeve and not be useful anymore. Rishkar would have a similar effect if Aeve is too big and then is dead in hand. Unfortunately I can’t think of good replacements right this second, but will come back and let you know when/if i do. More tutors certainly wouldn’t hurt if that’s what it came down to.

I have replaced Well of Lost Dreams with Altar of Dementia , which lowered this deck's average converted mana cost from 4.15 to 4.11, because, while the well is a great card, the altar fits the strategy of this deck far better, as it shall allow me to sacrifice creatures that I take from my opponents to fill their graveyards with even more creatures that I can steal.

seshiro_of_the_orochi, I like the suggestion, so I shall definitely consider it (ironically, I opened an Immersturm Predator from a Kaldheim pack, but I traded it, because I did not need it at that time; thankfully, however, it is an inexpensive card, so it shall not be difficult to obtain another one), and, actually, the predator is another sacrifice outlet for creatures that I steal from my opponents.

multimedia, yes, your advice is very sound, so I shall choose Altar of Dementia , since the fact that its ability costs no mana to activate is quite appealing.

Hey, sac outlets that cost no mana to activate are overall better than ones that cost mana. 3 mana to sac one creature and draw one card is a lot. Your Teneb deck is better than the other one so I will focus on that one.

Altar of Dementia gives you repeatable self-mill and/or opponent mill and being able to choose either one is versatile. Currently you're only using the strategy of reanimating your opponent's creatures with Teneb, but by adding self-mill such as Altar then you can abuse Teneb other ways by reanimating your own creatures.

Plaguecrafter , Demon's Disciple and Fleshbag Marauder can do work as sac outlets since they make all your opponents sac a creature, if they have one. They can sac themselves which gets them into your graveyard to reanimate and potentially repeat.

I've looked at both decks and left a suggestion at Tariel.

Regarding your question here: If you want to put thevsame card in both decks, I think Altar of Dementia is the stronger choice. Your commanders both gain value out of opposing graves. Looking more onto the details, I think Dementia is correct for Teneb, while I'd argue for Carnage in Tariel. The reasoning is linked to my suggestion: Immersturm Predator mitigates the randomness of Tariel's ability by exiling creatures you don't want to reanimate so only the prime targets are left. With dementia, you'll propably put tons of creatures into opponent's graveyards, which will usually decrease Tariel's chances of hitting something big. So Altar of carnage or maybe even Spawning Pit might be a better sac outlet.
