Contamination Discussion

Aphoticate on Commander Tier List [WIP]

2 days ago

I was wondering what you think of Chainer, Dementia Master Stax going up to tier 3? I only ask because my casual list can really go ham. I'm fairly confident that I could add lots of discard and other stax elements like Contamination to make it way more powerful.

Honestly, I don't know if it's actually tier 3 worthy, I was just curious to know your thoughts. The reason I personally like Chainer is he can be a mana sink for the mono B ramp cards like Crypt Ghast and Cabal Coffers . My primary win con is to sac/reanimate Gray Merchant of Asphodel or Kokusho, the Evening Star . Doing it with Mindslicer can be a decent lock too.

One reason I wonder if it could make a strong stax list is in the mass discard. If you can make everyone discard their hand and then play Chainer, you are basically the only person playing Magic having access to all creatures in all graveyards.

Just so I'm clear, I'm not claiming he should be tier 3, I'm just asking what you guys think. I haven't actually played any cedh games with him to make a claim like that.

If you want I could upload/post my Chainer list. It's pretty casual as is and may not be very helpful.

Gorbah on Bloodline of an Ancient Coven

Out : Phyrexian Reclamation In: Reanimate Why: Reclamation was to slow for me + when it was on the board i rarely used it...

Out : Vampiric Rites In: Contamination Why: First of all, Stax gameplay is my favourite playstyle! With all of the tokens its no problem to sac 1 at the start of my upkeep and Contamination is a wincon in this deck! I have enough mono black vampires in this deck to bring my foes down. The best time to drop Contamination on the board is when Edgar Markov is on the battlefield to pump up my vamps and make it a swift dead for my beloved friends around the table.

I think im close to the final version of my deck, I could use some sac lands to give it the final touch it needs but those are expensive but will be introduced soon..

Thanks for reading ! If u like my deck please upvote !

CyborgAeon on The Recursion Nightmare

Hi, I played Shirei off the cuff a few times as I saw he was cute. But I like your niche view of using wiping artifacts repeatedly.

Have you thought about: Canal Dredger (lets you recur destroyed/hated out pieces) Coretapper + Magistrate's Scepter for an easy 3 card combo? Run Snow-Covered Swamp so you don't share mana with extraplanar lens (but only if you insist on using it) Blood Pet - extra mana every turn. Makes for faster shirei Skittering Surveyor and Skyscanner are both card advantage engines with shirei + sac outlet

Furthermore you should run The Tabernacle at Pendrell Vale , Mox Diamond , Mox Opal , Dark Ritual , Culling the Weak , Mox Amber (since your entire gameplan is focused around shirei being in play anyway), Chains of Mephistopheles vs decks with draw power, Contamination , Imperial Seal . Now next is for sheer faster wins. Ad Nauseam , Pitiless Plunderer can function as a semi- Phyrexian Altar , Demonic Consultation so that you can find your win conditions faster, Tainted Pact is another competitive level backup but requires the rest of the deck to be tuned around it.

When alliegance set drops I'd also recommend Priest of Forgotten Gods

This is clearly a pet-deck. Play it however you want. But honestly? You need to make room for Toxic Deluge , Lake of the Dead , Strip Mine , Wasteland , Dust Bowl . In stax black needs every advantage it can get. But building up until you have a critical mass of mana like with Exsanguinate / whatever is just unrealistic in a competitive meta. It's far too easily disrupted.

A Crucible of Worlds & some fetch-lands would go well. That way at least you'd be able to gain mana advantage turn by turn with almost no loss. Lastly, try running Meteor Golem - I've seen him be busted with Scarecrone and other recursion effects, but ymmv. Especially if you don't like using sorceress queen.

MightyDarknut The deck you describe would never need Shirei and would be better as a Sidisi shell. Trying to involve Shirei means that one of 3 main stategies come into play:

1 - Go for a reanimator style list, with minor control elements. Abuse Apprentice Necromancer to the maximum, and have Shirei as a minor value pieces with some combo lines with Razaketh, the Foulblooded sacrificing creatures that trigger Shirei, so if the combo is disrupted, you have some board state to go off on your next turn. It could be a good mono-black combo list, as good as mono-black combo lists are in general, and can even have some very limited use for Shirei.

2 - Go for a stax list, abusing Shirei about as much as competitively viable as possible, trying to get good cards (think Bone Shredder ) that have innate value without Shirei and also a lot with, maybe 10-15 of these good useful creatures exist that work with Shirei and also aren't dead without like Heap Doll . Then run cards like Contamination , Smokestack , etc. and maybe even some hate pieces like Lethal Vapors if you are feeling... 'Out there.' Finish the deck off with a various amount of non-shirei based stax pieces like Sphere of Resistance , Thorn of Amethyst , Damping Matrix , Oppression , Bottomless Pit , Leyline of the Void , Chalice of the Void etc. and a large amount of instant speed interaction to hopefully survive the early game like Fatal Push , Dismember , Warping Wail , etc.

3 - Go with a Midrange combo list. Try to find some value-oriented creatures and a mix of interaction, maybe a few minor stax pieces that don't affect you, and then a bunch of tutors to find some hyper-card-efficient combo that may or may not interact with Shirei. Try some Ad Nauseam storm maybe, maybe a Buried Alive combo, who knows. Make it survive the early game a get their turns 4-5 for the midgame win, with a decent controlling backbone to lie on when you can't combo out as early as you would want, due to a stax piece you need removed or whatever.

NoOneOfConsequence on Commanders by Power Level [EDH Tier List]

No, they're not. Alesha's effect still sucks. Also, you're just flat-out wrong if you think using Fume Spitter every turn until there aren't any creatures on the board except your own isn't worthwhile. Same goes for Heap Doll , same goes for Harvester of Souls , same goes for Workhorse if you have something like Winding Canyons , same goes for literally 20 other creatures in the deck, like Noxious Toad (oracle text, it's each opponent).

Okay, lockdown isn't viable. Sure. That's why Alesha having to access to white for stax effects is so relevant, right? Mono-black has stax effects aplenty, and especially with Shirei--I can abuse Smokestack and Contamination to literally shut down everything.

It's entirely possible to keep anyone other than yourself from drawing anything but lands with Thoughtpicker Witch , and they'll be topdecking, at that.

You guys act like you know what you're talking about when you haven't even heard of most of these cards before, let alone played them/played against them.

Lil_Kalki on Threnody for the Victims of Dementia

ArchFline: I appreciate the tech! I’m not huge on Sundial of the Infinite mostly on account of having to end my turn just to save Chainer’s pets from exile. I have enough sac effects to ensure they’ll be okay in the long run.

Which leads me to...

dritchie: digging a lot of the suggestions. I used to run Disciple of Bolas but don’t anymore because if it’s my only critter (say, early game), it’s a dud. Geth, Lord of the Vault would be nice if I was relying on opposing graves (I aim to be a very self-sufficient Chainer deck due to various meta reasons) — same with Sepulchral Primordial and Rise of the Dark Realms, to a lesser degree. I don’t really want to play Ob Nixilis of the Black Oath mostly because, Daretti, Scrap Savant (in my Norin the Wary deck) and Teferi, Temporal Archmage (in my Aminatou, the Fateshifter build) aside, I don’t tend to like playing commander walkers in the 99. Desecration Demon gives opponents a choice to stop the thing which slows the game plan if abided. My opponent’s don’t tend to have a shortage of blockers or things worth sacking (yet not worth reanimating, oddly enough).

HOWEVER: I like It That Betrays as a consideration (and can do it in paper right now!), so I may take that into consideration soon.

Therefore, I am wondering what to cut for the following cards though (in order of priority): It That Betrays (since I own one already), Exsanguinate, and Contamination (these last two are lower priority because I don’t have them yet... truthfully I’d prefer Contamination before Exsanguinate but the latter is cheaper lol). Any ideas?

Hey welcome to T/O Lloki!

First thing first, I'm unsure if you know but Painter's Servant is banned in EDH unless your playgroup allows a certain amount of banned cards.

Now to the next part, it looks like you are going for a combo Teysa deck, so here might be some cards that can be considered:

Hope that helps! Feel free to ask for any advice as well!

tiagompm on Muldrotha and the power of infinity

3 weeks ago


I understand your doubts, and what could you advise me to "protect" the deck?

In relation to the commander, Muldrotha, the Gravetide is the "support" to complete several strategies but its true objective is to ramp to the deck with its ability to dominate the cemetery. To give you protection I have the Bear Umbra (only protection ...? What a delight this card with the muldrota!), I also have the Command Beacon that is indispensable for Muldrota! In my area there is a lot of control deck with many enchantments and a lot of removal, including Leyline of the Void that is a mess ... and many Bojuka Bog ... But this is part of magic, we will always catch counters our strategy and by this is that this deck does not focus only on the ability of the muldrota ...

You already have Reclamation Sage and Seal of Primordium, but you can for example change the combo of infinite turns (which is what I could not yet accomplish ...) Thopter Assembly and Time Sieve to include Acidic Slime and / or Caustic Caterpillar ...

Attention ... this deck is also a serious case for this type of opponents ... You always have the ability to be blocking their strategy with Contamination, or Decree of Silence, or Glen Elendra Archmage, or Glacial Chasm ...
