Chromium, the Mutable Discussion

Also, Chromium, the Mutable is a powerhouse. Such a workhorse, and might even be about as good of a finisher as AEtherling in rtr standard was.

Yea, unfortunately Teferi, Hero of Dominaria is way too expensive right now too. I picked mine up during prerelease since I kinda knew how ridiculous he was going to be, and control walkers are just historically expensive.

Hey thanks for the feedback both of you. I have made some changes such as doing a split of Essence Scatter and Syncopate. Then I dropped the 2x Cleansing Nova and added the 4x Sinister Sabotage.

What are your thoughts Chainer_the_Dementia_Master on Chemister's Insight? I see you haven’t bothered to use it in your list and instead have gone with Anticipate.

I wouldn’t mind having a third Teferi, Hero of Dominaria here, but considering I only own one currently (they aren’t exactly cheap either) and probably will buy some Vraska's Contempts instead of a third teferi if I build this deck rather than retire it with rotation.

In place of what would be a teferi, I was planning on having an extra creature as a finisher and that’s likely to be Chromium, the Mutable.

You might want to consider Ritual of Soot here, as well as of course Guildmage's Forum if you really are keen on using Chromium, the Mutable as you will need something to replace Aether Hub. (I’m not sure if you would ever want to ever do this lol, but there’s always the option now of running Chromatic Lantern to help out your mana base too).

Have you ever considered Nezahal, Primal Tide much for your sideboard? It’s much easier to cast than chromium.

I considered Seal Away for a while and it was originally in my sideboard, but then I wasn't sure when I'd use it over Cast Down. Now I realize you're right, indestructible things. Ill out it in the maybeboard for now until I decide what to cut for it. Also Chromium, the Mutable is in the sideboard for any control matchup, or any other deck that races to combo of. It's a big body that's hard to deal with. And I I leave my mana untapped I can flash it in during combat.

SMASHER101, Zur the Enchanter, is a great commander option, but the reason this is a Chromium, the Mutable deck, is because my playgroup decided we would all build new decks, featuring an elder dragon, from the M19 set, as our commander and build a deck around the dragon of our choice. Mine is the obvious choice. I can’t help that it so happens to play Zur the Enchanter a lot.

Hey, nice version of Dragons.

I don't think you need Nicol Bolas, God-Pharaoh or Dark Intimations. Consider cutting them for another two drop, 2x Abrade? I also think until rotation Glorybringer is much better than Lathliss. Glorybringer is not legendary and until rotation it's the best Dragon in Standard. Consider 4x Glorybringer and 1x Lathliss? Currently this deck lacks creature removal, more Glorybringer solves this problem.


For the sideboard I suggest planning it majority for aggro and control matchups. Dragons already have a good midrange matchup especially with Liliana DM. Unlicensed Disintegration is a good unconditional creature removal spell that's much easier to cast than Vraska's Contempt for midrange matchups. In the sideboard against aggro consider Magma Spray and more Abrade? For control consider Duress, Arguel's Blood Fast  Flip, Negate, Doomfall and Chromium, the Mutable. There's some combo decks in Standard (Mono Blue Artifacts and God-Pharaoh's Gift) Sorcerous Spyglass and more Abrade is good against them. Spyglass can also shut down Teferi or Karn in control/midrange matchups.

Consider this sideboard:

  • 3x Spray
  • 2x Abrade
  • 1x Disintegration
  • 3x Duress
  • 2x Negate
  • 1x Blood Fast
  • 1x Doomfall
  • 1x Spyglass
  • 1x Chromium

Good luck with your deck.

Hey, looks really good. I really like the deck name :) Good job coming up with a clear Dragon strategy and the numbers on the cards you choose are well thought out.

I agree with you, glad you came to the conclusion that Primevals' Glorious Rebirth is not worth building around. The Eldest Reborn is however a great addition with all the self discard happening here. Like Rebirth it too can reanimate something, but also has other uses, disrupts your opponent. The biggest problem with Rebirth is the restriction of needing a legendary creature or Planeswalker to cast it, Reborn doesn't have this restriction.


I'm on the fence about main deck 3x Dragon Egg. It has good interaction with Dragon's Hoard, but that's it. There's a lot of three drops here and I feel that Egg is the least good of the them. Spit is good with all the self discard as well as being a recurrable removal spell. Egg to me seems like a fine sideboard card, but not main deck. For the time being I suggest playtesting without Egg. In it's place consider Lightning Strike? Currently you don't have a two drop removal spell. Post rotation Strike will be a good one for red. Pyromancer and Voice are good two drops for the strategy here, but they aren't the best when against aggro. I think you can trim one of them down to a 3 of to add a fourth Strike.

Here's an example:

  • 4x Strike
  • 3-4x Voice
  • 3-4x Pyromancer

  • 4x Hoard
  • 4x Spit

You can go either way with Pyromancer or Voice. Pyromancer is the slowest of the self discard, have to wait a whole turn before you can use him to loot once. But he's a body as well as a removal spell later in the game, gives you more options than Voice. Voice however draws you two cards for one loot right away.


If you're choosing to not play Gift of Paradise then I suggest playing more black than green. Black is needed for The Eldest Reborn, can't use Territory to make black mana to cast it. You can however use Territory to make green mana for the Dragons, green is currenly only here for Dragons. Black also gives you some removal options, Cast Down and best of all great sideboard options. Green is still needed here because a lot of the Dragons are green, but black is also needed and I suggest playing more black than green. For the time being you'll want a Swamp in the manabase to help to cast Reborn if you don't have a Hoard in play.

For the manabase later on consider this:


4x Demanding is great, but my last suggestion is cut 1x Palladia-Mors, the Ruiner for a third Verix. Palladia is good, but he's yet another six drop Dragon and will be the hardest Dragon to cast. For these reasons I would play him as a 1 of. Verix is the only mono red four drop Dragon and due to the all the other Dragons being a higher CMC more Verix is better for the mana curve.

Dragons are good now as a budget deck because nice upgrades can be made as you get more cards or funds especially lands. Nicol Bolas, the Ravager  Flip is the biggest Dragon upgrade, but also more Sarkhan, Fireblood and 1x Chromium, the Mutable much later on for the sideboard for control matchups. All these cards can really strengthen a Dragon strategy. My advice however is to focus on improving the manabase before making any other real expensive purchases.

Hey, consider Glimmer of Genius and 2x Aether Hub main deck? Since Kaladesh Glimmer has been the go to draw spell for control. Without it I think the way this deck is currently constructed there will be consistency issues. Consider cutting 3x Opt and 1x Invoke for 4x Glimmer? Opt is fine, but Glimmer is much more powerful draw spell especially with Gearhulk. Hub helps a lot for a three color manabase and Glimmer powers Hub. Until rotation the exile of Forsake is more important than the life gain of Invoke. Exile is for Scrapheap Scrounger and most of all God-Pharaoh's Gift. These cards are difficult for control to beat if you can't permanently exile them.

With only eight sources of red in the manabase Chandra is not worth it. Consistently it will be too difficult to cast her. I suggest cutting Chandra for 2x more Teferi. Competitively he's the reason to play Azorius control and the manabase can support him. Consider 1x Commit main deck and 1x more in the sideboard for red matchups? Commit is the only way blue control can stop a lethal Banefire and it doesn't actually stop it, it delays it. Banefire is a thorn in control's side and I think it will be even more a problem post rotation because Commit is rotating. Post rotation white has Shalai, Voice of Plenty who is protection against Banefire, you have hexproof, your opponent can't target you.


Some options for post rotation, I think Blink of an Eye can be a go to spell for control. Currently it's already being played as 1 of and 2 ofs. Blink gives control instant unconditional nonland permanent bounce with draw, works well with Teferi. Anticipate or Opt can replace Glimmer post rotation, both work well with Teferi. Currently Syncopate and more Essence Scatter can replace Disallow. I expect there to be a good a counterspell in Guilds of Ravnica because both Izzet and Dimir are guilds in the set. These guilds are traditionally control guilds and Wizards is going to push Grixis colors because of their new Dragon money maker Nicol Bolas, the Ravager  Flip.

The mana situation post rotation is going to be interesting for control decks playing white. I think white is going to be difficult to play as a dominate color for control. Azorius and Orzhov are not in Guilds of Ravnica. Boros and Selesnya are in the set. You've done some real good thinking ahead here because as it currently looks like post rotation Jeskai can be one of the best colors to play white for control. Due to the post rotation mana situation, Esper only has playable Glacial Fortress and Isolated Chapel and some Plains. This is only enough white to splash Teferi and a few other single white cards, but not enough to play Settle the Wreckage, Cleansing Nova and Lyra Dawnbringer.

Jeskai is different because you'll have Fortress, Clifftop Retreat and the new Boros dual land hopefully Sacred Foundry in Guilds of Ravnica. This is enough white dual lands along with Plains to play Settle, Nova and Lyra. With Gearhulks rotating, control needs a new finisher. Which ever way control will go post rotation can be determined by what color has the better control finisher. Esper already has one in Chromium, the Mutable lets hope Jeskai gets one in Guilds of Ravnica.

If this advice is helpful I can give more advice about the sideboard. Would you like more advice?

Good luck with your deck.
