Chromium, the Mutable Discussion

Skyler1776 on Flashdance!!

Thanks Hexadlexagon! I considered green, but I value cards like Chromium, the Mutable, Teferi, Hero of Dominaria, Azor, the Lawbringer, and Nezahal, Primal Tide in Control mirrors and decks like Big red and Monored. My original deck was bant with Multani, Yavimaya's Avatar and Trostani Discordant, but I found it a bad matchup against those builds.

Steve,

Lots of good feedback here! I will try to hit everything.

Carnage Tyrant is absolutely a problem, and as I mentioned more Settle the Wreckage and Cleansing Nova would be some of my first moves in G2 or G3. I struggle against it in G1, but in G2 and beyond, Unmoored Ego hurts bad. Detection Tower seems possible, but I don't want more than 1, and if you don't get it then it won't matter anyway.

As far as removing my own creatures to open up spots for other cards, I think I would take out Azor, the Lawbringer before Chromium, the Mutable. The pseudo hexproof is better than no hexproof, and it can flash in on CT. I'm also considering Nicol Bolas, the Ravager  Flip, as flipping him can be damn near a win-con, or Niv-Mizzet, Parun, as there are a fair number of instants and sorceries.

I considered Ral, Izzet Viceroy but decided against it because I think Karn, Scion of Urza does things better. I like that Karn provides a way to get the 2nd card back. If you draw two good cards, it hurts to put one in the yard since I don't do much in the way of recursion, especially with spells.

For card draw, I think Chemister's Insight might go to the board and switch with Risk Factor against those life-gainy type decks, but so far Risk Factor has worked pretty smoothly (if you're low life and let me draw, that's the preferred outcome). With Karn and Search for Azcanta  Flip, I have a pretty decent setup to see cards or filter them, so even if its not more draw the draws are more efficient.

The one-ofs are mostly in there for fun, and I have a soft spot for Thaumatic Compass  Flip. Its been really helpful against Izzet Drakes/Izzet Phoenix decks, and even helps stall out something like Adanto Vanguard, which can be difficult to remove.

Justice Strike has saved me so many times against Lyra Dawnbringer when I didn't have a counter in hand and against Niv-Mizzet, Parun or a big Enigma Drake or Crackling Drake. On the draw, its hard to have a counter for a T3 drake who can sit on the board and just get big. Might go down to 2 in the main, but I would be hesitant to take it out altogether.

Thank you for all the feedback, I will keep adjusting the deck and trying things out, and with Orzhov, Azorious, and Rakdos all in the next set I'm sure there will be a few new cards fighting for spots.

Hey!

First of all: I like your idea! In your description you mention Carnage Tyrant to be a real problem to deal with (because it is a 3-turn-clock and has hexproof as well). I may have some ideas ...

1.) What of making the whole approach more like a big toolbox? Max out the Mastermind's Acquisition and design your sideboart to provide some options if you need them.

-2 Chromium, the Mutable, -1 Rekindling Phoenix // +3 Mastermind's Acquisition

2.) I feel like some of your one-offs may not show up often enough, when you need them, despite having some nice carddraw. Personally I would run more removal to deal with the biggest threat I sense for a build like this: (really) fast aggro decks

-1 Profane Procession  Flip, -1 Thaumatic Compass  Flip, -1 Treasure Map  Flip // +1 Deafening Clarion, +2 Settle the Wreckage

Why that way? Simply because Settle the Wreckage gets rid of that big, unfriendly dinosaur. Procession and the transformed compass will not handle it on their own (you'll need a Detection Tower, but the requirement of 4 colors won't leave really much space for a colorless mana source, I think).

3.) Ever thought about Teferi's "brother in arms", Ral, Izzet Viceroy? He provides cardadvantage, acts as some kind of removal (with enough instants/sorceries he maybe shoot something big other than a tyrant) and his Emblem is kinda both ...

4.) I Don't think you really need 3 Justice Strike in the mainboard. Best thing to answer a threat is on the stack by countering it:

-1 Justice Strike // +1 Ionize

5.) I would try to add some other carddraw besides Risk Factor. On low life, no sane opponent will take the damage, so you'll safe to say "I draw three". Unfortunately there are some decks with many lifelink or lifegain in general out there. They are happy to take the damage because it won't matter that much to them and you'll end up with an empty hand. The most reliable carddraw in my opinion would probably be Chemister's Insight, Radical Idea, and Divination.

6.) Following the thought from number 1.), here are my suggestions for adapting your board:

-1 Arguel's Blood Fast  Flip // +1 Chromium, the Mutable

-1 Doom Whisperer // +1 Settle the Wreckage (Yes, you really don't like that dinosaur!)

-2 Ixalan's Binding // +1 The Eldest Reborn, +1 Demanding Dragon

-2 Thought Erasure // +1 Duress, +1 Vona's Hunger

This would be my thoughts so far. Maybe you'll need to up or down one or another land to provide your colors, but the actual completely even distribution seems fine to me.

Greets, Steve

This is a bit off topic, but even for a Mid-Power General, I can say from experience that Chromium, the Mutable as a finisher alongside Approach of the Second Sun in an Esper control shell, while it’s no Banana man, it’s still really fun to play and can hold it’s own against competitive decks... if played right! Essentially it’s a deck of answers and good Esper value, with a very light stax package (Arcane Lab, Stony Silence, silences, etc). You gotta be a bit more careful in your answers though!

why do you only one win-on, Chromium, the Mutable? what if he is at the bottom of your library, you will mill yourself out before winning.

Wow you were not kidding when you said you had massive changes for this deck. Most of cards that you added and cut seem to make sense as a whole, but there are a few changes I found surprising. As you said, you wanted to cut cards that only helped you cast creatures, so taking out cards like Urza's Incubator makes sense, but I was a little bit surprised that you took out Selvala, Heart of the Wilds. This card is insanely powerful in creature decks like this one, and gets even better with cards like Paradox Engine. I personally am also not a fan of having most of your removal only dealing with creatures, other than the Cyclonic Rift and Vandalblast, which means you only have one card that deal with enchantments, but it doesn't destroy it, just bounces it to hand. I feel like one of either Swords to Plowshares or Path to Exile could be something like a Beast Within or Anguished Unmaking. The lack of basics was surprising, but if your meta doesn't run anything like Ghost Quarter or Field of Ruin, then it really isn't that big of a deal. I also feel like Homeward Path and Dragonlord Silumgar are kind of a non-bo, and I think that the dragonlord could be swapped for something else for this reason. I do like the addition of Lotus Cobra as it works insanely well with fetch lands, as being able to produce up to three mana off of one land is insane. I also like Boneyard Scourge and Thunderbreak Regent. They are definitely some of the weaker dragons, but having recursion or punishment for your opponents hitting your stuff, as well as being early game beaters is really good. Chromium, the Mutable was an interesting addition that I didn't expect, but flash, uncounterable, built-in protection, AND a 7/7 for six mana is pretty powerful. Overall, I think the new decklist is insanely powerful, just a little lacking in more versatile removal.

Grixis776 on Magic discussion pet peeve

Oh man have I got a story for you guys. FNM, me and two other friends play in a pod with another regular at the store. I’m playing Vorthos bolas, Friend A is playing karlov, Friend B is new to EDH and is playing a jank Chromium, the Mutable deck, regular is playing karthus. Now we all were pretty calm and were looking to have fun. Pretty early we all start talking about what our decks are supposed to do. Karthus player just tries to shut down all of our decks with “oh I’ll just kill that lol” and “I can just steal it with my commander!” Statements. Karlov player just kills all of his ramp out of fear of karthus comboing off or killing us all super easily, fair reasoning. Karlov exiles a Goreclaw, again, out of fear of karthus progressing extremely quickly. Karthus player immediately turns into a child, concedes and whines “I was triple teamed!” I wanted a fair game!” He was above 35 life when he conceded and only the karlov player targeted him. Moral of the story? Don’t try to brag about your deck on turn 3 or threaten to destroy everyone easily if you wanted a “fair game.” Also this is just another reason why you shouldn’t have hypothetical arguments, it starts to put fear in your opponents so now they all begin to target you for the rest of the game when in reality your deck isn’t even that powerful. Oh and be a good sport.
