Caerwyn on Red Stax Enchantments

Stax is generally a cEDH strategy--more casual metas do not take kindly to decks that shut down playing the game, and will generally make that clear to the would-be Stax player. I think the red Stax pieces you outlined are strong cards for tuned, casual metas--but they're not enough to see play at the competitive level where you start to see more Stax.

Generally, cEDH games tend to have a lower reliance on creatures, decreasing the efficacy of Smoke and Mudslide . There's just much more utility in shutting down lands--everyone needs lands, regardless of if you are running creatures, artifacts, spellslinging, etc., and Winter Orb effects have a nice synergy with generic tax effects, like Static Orb . The anti-creature Red Stax effects are only going to work against a few decks, such as those with Green, whereas other options cover the whole table. They're just far to susceptible to what your opponents are playing.

Now, Tectonic Instability is a card that goes against lands, but it's really easy to circumvent. In the early game, when you're likely to use all your lands on a turn, you can simply tap for mana in advance of Instability's trigger resolving, and your play is unimpeded. You also give your opponents the option to simply not play lands. As the game progresses, and the need for new lands diminishes, Instability only gets worse.

I just learned of some awesome new red stax enchantments and was wondering why they don't see more play.

Smoke is like a red winter orb for creatures. Most competitive green decks run a suite of 1 mana cost dorks, so this slows them drastically. Slows draws from Tymna, and beat down from stax decks. It has some serious defensive applications against wide decks.

Tectonic Instability seems like an obnoxious card, and potentially back-breaking with Winter Orb Static Orb Hokori, Dust Drinker Mana Web . At the very worst, this card reads "Your opponents lands ETB tapped"

Mudslide is another creature hoser, and while players can get out of it, it seems strong in combination with other taxing effects like Sphere of Resistance and friends. Once again this card robs mana dorks of their speed and resilience.

Are these stax effects strong enough to be viable?

More red/white hate:

Price of Glory

Aven Mindcensor

Loxodon Gatekeeper

Imposing Sovereign

Tectonic Instability


Sulfuric Vortex

Blood Moon


Heat of Battle

Heat Stroke


I see you are already running some creatures like Leonin Arbiter that does what Stranglehold does, but thought i throw the suggestions out there anyway.

Another option for ramp which I'm sure you are well aware of is Smothering Tithe .

And i would personally run Vandalblast over Mogg Salvage unless it works well in your meta. Dont get me wrong it’s a sweet way to cheat cmc but it’s very contextual.

Maybe Assemble the Legion or Crescendo of War for funsies?!

Storm Cauldron seems like a shoe-in for this type of deck.

Tectonic Instability maybe?

From the Ashes if your meta plays with a bunch of nonbasics.

Woops! I swore I checked your enchantments before I suggested Captive Audience. Sorry about that. If you want to take the deck into a more Cruel-control direction there’s also Sulfuric Vortex , Price of Glory , Psychogenic Probe , Tectonic Instability , and Stranglehold . All would follow that theme that Captive and Havoc tap into. I know you’re deck is more about the creature tribal so no worries if these aren’t up your alley.

Very Solid. There are some sub-optimal choices imo, but overall, nicely focused.

Shock is just not worth the slot in EDH. Leyline of Lightning is ok, but can be pretty mana intensive to keep using, especially in a land destruction deck, I don't see it being worth it. Guttersnipe is always nice, but with you creature wipes, you might kill it without a big payout. Keep an eye on how many X spells you have too, you might be shooting yourself in the foot, unless you add more artifact ramp, like a Fire Diamond and Ruby Medallion . Treasure Nabber can put everyone between a rock and a hard place if they are using artifact ramp. You'll also need some more card draw so that your single target removal keeps up with the board. Pyromancer's Goggles can help keep you up with 3 other players. If you fall behind, Acidic Soil and Price of Progress might be nice backups. Mana Web , War's Toll , Tectonic Instability might slow everyone down too.

Where is Blood Moon !? If you want to get pricey, Extraplanar Lens with Snow Covered Mountains is just mean with Blood Moon

Red has a huge weakness: Enchantments. You might want to add some enchantment hate, just in case. Even though they are costly Meteor Golem and Spine of Ish Sah are ok. Enchanter's Bane could fit in here real well.

I know you love your goblins, but I think Stuffy Doll is just better than Mogg Maniac . If you really want to anger people, mass land destruction is best: Ruination , Obliterate , Jokulhaups , Decree of Annihilation , and Impending Disaster are the most well known. Even an early game Tremble could be infuriating. If you your deck can get some tokens, or just fodder creatures Shivan Harvest might be fun. Mine Layer would cause a lot of frustration. So would Price of Glory , but it can hurt you too. I personally love Volcanic Offering because it can make someone mad at someone else. Bend or Break can divert some attention from you too.

Burning Earth Fits this deck pretty well. Maybe, Burning Sands too.

You don't need to take any of these suggestions, but they might be nice ideas for a sub theme, or a different way to think about how the deck could be run. I am not looking forward to this monstrosity lol

  • ...but MLD is one of the most effective anti-control measures. As I said further up this post, it is a strong means of making sure those players "use it or lose it". Pretty difficult to play "in response" with a huge stacked hand with MLD.

  • Nikya of the Old Ways + Assault Suit would be another way to hose people & you can change selection, & lend people a beatstick.

  • I've used a ridiculous amount of control-hosing as it is by far the most prevalent strategy in my meta, same as the other guy, filthy control-friends. A low-cost card that gets em' every time is: Tectonic Instability ... crazy to think I picked up 7 of them for 20cents apiece when Price of Glory has its' price tag.

Well, if you're taking the evil root, perhaps War's Toll? Tectonic Instability?
