Deck Title: Ascension Through Unity – Atraxa cEDH Food Chain

Commander

Atraxa, Grand Unifier
Color Identity:


Introduction

Welcome to Ascension Through Unity, a competitive EDH build centered around Atraxa, Grand Unifier, the ultimate value engine and a uniquely powerful commander that bridges midrange resilience with combo potential. This list leverages the raw card advantage of Atraxa’s ETB trigger to dig for win conditions, interaction, and fast mana — all while supporting a Food Chain combo core.

This deck is tuned for high-level pods and aims to win fast, interact precisely, and grind smart when necessary.


Win Conditions

Primary Wincon:
- Food Chain + Eternal Scourge / Misthollow Griffin / Flesh Duplicate
Infinite creature mana via Food Chain and one of the exile-recurring creatures.
→ Cast Atraxa, Grand Unifier, dig for Thassa's Oracle or Tainted Pact / Demonic Consultation combo.

Backup Wincons:
- Thassa's Oracle + Tainted Pact / Demonic Consultation
- Finale of Devastation for lethal with infinite mana
- Displacer Kitten combos with The One Ring, Teferi, Time Raveler, or mana rocks for infinite value/actions


Notable Synergies


Staples and Interaction

This deck plays nearly every blue interaction spell you’d expect: - Free Countermagic: Force of Will, Force of Negation, Pact of Negation, Mindbreak Trap, Flusterstormfoil
- Removal: Swords to Plowshares, Abrupt Decay, Chain of Vapor, Toxic Deluge, Culling Ritual
- Tutors: Vampiric Tutor, Demonic Tutor, Worldly Tutor, Enlightened Tutor, Imperial Seal

And it runs every relevant fast mana: - Mana Crypt, Lotus Petal, Chrome Mox, Mox Diamond, Mox Opal, Mana Vault, Ancient Tomb


Why Atraxa?

While many commanders offer value, Atraxa’s Grand Unifier trigger is uniquely broken in a deck like this. With a proper build, she can hit: - A creature (e.g. Eternal Scourge, Deathrite Shaman)
- A non-creature spell (e.g. Demonic Consultation)
- An instant (e.g. Swan Song, An Offer You Can't Refuse)
- A sorcery (e.g. Finale of Devastation)
- An artifact (e.g. Sol Ring)
- An enchantment (e.g. Rhystic Study)
- A planeswalker (e.g. Teferi, Time Raveler)

This makes Atraxa a one-card value engine that refills your hand and pivots you into a win turn with proper sequencing.


Power Level & Goals

This deck is firmly cEDH (power level 9.5–10). It’s built for pods where interaction is heavy, turns are fast, and wins are clean.

You’ll thrive if: - You can protect Atraxa, Grand Unifier for at least one trigger
- You pilot your combo lines efficiently
- You mulligan aggressively for interaction or ramp


Mulligan Strategy

Look for: - Turn 1–2 dorks/rocks + tutor
- Food Chain + exile creature opener
- Strong card draw pieces + interaction
- Always mull away clunky high-CMC hands


Weaknesses

  • Susceptible to Drannith Magistrate (unless we remove it)
  • Hate for graveyard/exile recursion (Rest in Peace, etc.)
  • Heavy counterspell matchups if we stumble on mana

Closing Thoughts

Atraxa, Grand Unifier doesn’t just unify card types — she unifies power, control, and combo under one elegantly devastating package. Whether you’re tutoring with efficiency or slamming a turn 4 Food Chain win, this deck rewards mastery and punishes hesitation. Perfect for cEDH players who love versatility and inevitability.


Thanks for reading! Let me know if you want a sideboard package or metagame tweaks.

Andramalech on Favorite plane and why?

1 month ago

I have love for several different planes.

Mirrodin/Argentum - Karn is one of the oldest characters that I associate myself with, and I happen to really love who and what Karn has become to the world of MTG, since Urza (imo) after encapsulating his character, wasn't someone worth keeping up with. Karn seems timeless and like someone who can be revisited over and over again with new relevance. Mirrodin developed this great butterfly effect where "the actions you didn't even realize you were taking shaped an entire civilization in your absence."

Kamigawa - a typically over-looked plane and set respectfully due to how over-nerfed everything needed to be in Karn's power-hungry wake (i Joke). but some of my favorite characters like Tetsuo Umezawa can be associated to this plane. Not only that but the lineage traces and it just tethers so many different parts of magic together. I am infatuated with the original artwork for Sensei's Divining Top. Much like I am for Mox Opal.

Kiora - relatively un-discovered but I theorize that I could see some developement for Nekusar, the Mindrazer if they ever confirm his home-plane.

Muraganda - I love the general energy of the plane and after Aetherdrift recently, I want to revisit for more development.

Amonkhet - Hazoret is a total baddie and I'm still a bit heartbroken over the death of Oketra, but I like how the plane generally shapes out it's higher-tiered characters such as Hazoret, Oketra, Bontu, Ketramose, etc.

Ah thanks Cloudy2024, I guess it’s clear I haven’t revisited this one since Mox Opal was reinstated. I’ll have to think carefully on adding it since it’s über expensive, but maybe one or two would work well.

cool deck, well thought out , why not use newy unband Mox Opal to ramp? also Spell Pierce might be a good sideboard card. overall, i think this deck is heading in the right direction for a winner!

I test-played a bit and I think I got the lands to work well!Hallowed Fountainfoil seems to be a good land fix and much to my despair I think I have to remove The Ozolith to add one land in its place because the lands just were not consistent enough. (especially trying to get for a Counterspell, Sink into Stupor  Flip, or if I wanted to cast two cost cards. (this is part of the reason why I chose Metallic Rebuke over Counterspell before I updated my deck because getting double blue seemed tougher. but I think seventeen lands plus the Mox Opal and Springleaf Drum are good and the manapool seems much more efficient. I decided to keep the Darksteel Citadel because for artifacts entering and on the board for affinity I seemed to notice a considerable difference if they were not artifact lands. the Steel Overseer seems to be pretty strong especially if I have a bunch of Ornithopter or Memnite then I can buff them and make them more of a threat. I also had the crazy idea of adding another copy of Shadowspear because of the +1+1, trample, and especially the lifelink if the game is longer and I needed it. however, I am not quite sold on the idea. I would love to have one copy of The Ozolith, but I am unsure what to remove. I am considering removing one of the three Kapa Cannoneers Or one of the two Emry, Lurker of the Loch. but I am just not confident about removing those cards that seem essential for this deck. ); would love to hear from you and thanks so much for helping kamarupa! without you, I got no clue what I would have done!

This mono blue build is interesting. I'd be curious to hear your thoughts on the advantages of this build over an Azorius version that can support Portable Hole, Dimir with Basim Ibn Ishaq, or izzet for Galvanic Blast? Metallic Rebuke seems like another very popular choice which you have omitted and I'm curious about this decision as well.

In my opinion, the biggest advantage of Mox Opal is its ability to colorfix in an archetype that uses several colorless lands, and of course the fast mana aspect. To get maximum payoff from these characteristics, you'd either want more interaction b/c you'll have that extra mana up more often. Or fatter, more resilient bombs you can cast 1-2 turns faster than normal. Kappa is great, but aside from this I think the top-end card options are rather limited in blue. I have been working on a hybrid affinity/ponza build that really pushes these ideas, if you'd like to check it out!

With December 16's banned and restricted announcement, I have removed Faithless Looting, Green Sun's Zenith, Mox Opal, and Splinter Twin from this list and added Amped Raptor, Jegantha, the Wellspring, and The One Ring to this list, and I am very sorry that I took so long to update it, as I have been very busy, with Christmas approaching.

Another thought: Mox Opal requires sort of an "infrastructure" for the Metalcraft condition to be online. One popular option to do that with as little opportunity cost as possible would be Darksteel Citadel or Treasure Vault, which is also an artifact.

Other ideas could be Roadside Reliquary or The Mycosynth Gardens (or other suggestions we previously talked about), depending on where you want to go with the deck. What vector would you like to improve anyway? Where is it struggling? How is playtesting going so far?
