Altar of Dementia Discussion

You could consider Altar of Dementia or Altar of the Brood for infinite mill, Blasting Station for infinite damage, Phyrexian Altar for infinite rainbow mana. Nice deck!

Riddlekeeper seems like an upgrade to Ice Over

The Altar of the Brood + Undead Alchemist combo also gets improved a lot by playing Altar of Dementia, to the point where you can get instant mill combos pretty fast on creature heavy decks.

I have a deck focused on that combo over here:

I'd add Fleshbag Marauder and Slum Reaper as redundances of Merciless Executioner because the effect works great with your commander.

I'm sure you know these two, still, worths the mention: Cabal Coffers and maybe Urborg, Tomb of Yawgmoth to turn your nonbasics into swamps. Could prove interesting with Filth on your graveyard.

You can get more advantage of your commander's ability if you do the sacrifice: Typical sac outlets like Ashnod's Altar, Phyrexian Altar, Altar of Dementia, Carrion Feeder, Razaketh, the Foulblooded, Sadistic Hypnotist, Viscera Seer and also, sac fodder: Bloodghast, Bloodsoaked Champion, Nether Traitor, Reassembling Skeleton.

Also, what do you think about Horobi, Death's Wail?

CMGraves on Responding to resolution of spells ...

1 week ago

My friend and I were discussing a situation. I have 10 permanents (one of which is Zombie Infestation and 20 cards in hand. My opponent has 20 permanents and 2 cards in hand. I cast Balancing Act and it resolves. My opponent sacrifices 10 permanents then I discard 18 cards to Zombie Infestation and put 9 Zombies on the field. My friend says this wouldn't be allowed because you cannot respond to the resolution by "ignoring" the effect. He says to take Thoughtseize as an example. I couldn't respond to Thoughtseize by discarding the chosen card along with another to Zombie Infestation. Likewise as another example, if I had more permanents on the field, I couldn't allow Balancing Act to resolve and then sack all my creatures to Altar of Dementia thus reducing the number of permanents I control to less than my opponents. I think my friend's right but at the same time in the first scenario, I'm not changing the outcome or "tricking" the spell as I still go down to two cards in hand. Who is correct? Thanks

WalkingIllusion: I'm already running most of those combos, if you look in the "Win Conditions" section of the deck description :) I'm running Murder of Crows already, but I prefer to use Altar of Dementia/Phyrexian Altar in place of Blasting Station. Not to mention Skullclamp+ Altar, or Kindred Discovery haha.

Thanks for your comment! You're welcome to upvote the deck if you think it's solid ;)

On my Locust Deck I set up 3 possible win conditions, depending on the deck you're facing of:

1- Aggro. Just draw-swarm throw some wheels and pump with Gravitational Shift, Shared Animosity, with an always funny overloaded Teleportal.

2- control/direct damage. We assume we cannot attack for some reason or we must just stop some threatening creature Opposition, Shivan Harvest, Goblin Bombardment, Kyren Negotiations, Psychosis Crawler, Throne of the God-Pharaoh, Impact Tremors, and our beloved Purphoros, God of the Forge. In most of the cases we draw to create locust that will be used as gun-powder

3- Win by MILL. Yes. Here we can use two very understimated cards which are Sphinx's Tutelage and Altar of the Brood. The Altar is sick in this deck because everytime you draw, every enemy will mill the same. Make a Wheel of 7? they also mill 7 [and you have the locust BTW]. Altar of the Brood and Fascination act the same. If you sac your locusts to an Ashnod's Altar, you can draw-kill someone with a Stroke of Genius or the like.What about killing one opponent with 10 locusts pumped by shared animosity and then sac to Altar of Dementia to insta-mill another opponent? LOL.

anyway, that's my deck built on a relative budjet plus the cards I already had

K34 on A question of cmc preference

Having access to the right colors, and tutors for both, so equal playability is otherwise not an issue:

Do you use a 1 drop creature with a color requirement or a 2 drop artifact that has no color requirement when they both give you access to the same ability?

Example given: would you run Carrion Feeder or Altar of Dementia? There are minor differences, but for the sake of the discussion lets pretend the abilities are identical.

Step one get Combo by having it... drawing in to it by Worldly Tutor or Green Sun's Zenith.

Why Run 20 normal Mana = because meh... you can fix mana on your own... also cost

Combos that win:Melira, Sylvok Outcast + Vizier of Remedies + Devoted Druid = All the mana
Melira, Sylvok Outcast + Vizier of Remedies + Phyrexian Altar + Presist = All the mana
All the mana win = Walking Ballista

Melira, Sylvok Outcast + Vizier of Remedies + Any persist + Blasting Station or Altar of Dementia
Damage win or Discard win

Melira, Sylvok Outcast + Vizier of Remedies + Anafenza, Kin-Tree Spirit + any persist = Big Guys

Side board Things = Mana Ramp + removal + hex proof
Hex Proof Protect the combo...
Blossoming Defense = not this turn you don't (1 Mana)
Swiftfoot Boots = Never again (2 mana+1 )
Lightning Greaves = 2 mana never again

Mana Ramp
Birds of Paradise = 1 mana any color for 1 (also good flying blocker)
Noble Hierarch = 1 mana And you can get white or Green

Land Tax only better if you are losing on land
Tithe (You have the draw and only 1 Mana this is a good fix)
Weathered Wayfarer (again you have to be behind... but any land is amazing)

Swords to Plowshares- you don't care about life totals...
Path to Exile - works well with mana ramp white...
Lignify- 0/4 but oh well who care about blockers...
Condemn - Bottom of library works better then graveyard most of the time

Grave Yard Hate:
Tormod's Crypt : 0 cost woot woot
Scavenging Ooze : +1/+1 please
Scrabbling Claws : by by cards + draw

Cards to remove when side boarding

Anafenza, Kin-Tree Spirit = (very limited in what it combos with and a lot is required)
Aura Shards = (this should be on the side as well... but switch it out for other Removal first by deck)
Altar of Dementia = (This works with more cards; Remove last I think)
Phyrexian Altar = (you have another ALL THE MANA COMBO WIN Remove if you want to)

Again know the deck you are playing: Play the cards in the side to deal with things you can't have hurting you.
