Opposition Agent

Creature — Human Rogue

Flash (You may cast this spell at any time you could cast an instant.)

You control your opponents while they're searching their libraries.

While an opponent is searching their library, they exile each card they find. You may play those cards for as long as they remain exiled, and you may spend mana as though it where mana of any colour to cast them.

Destroyerbirb on K'rrik Son of Yawgmoth 2.0

3 days ago

For cuts I would recommend:

Professor Onyx - While Liliana's side job is beneficial for society (educators are very important, especially those who help us raise people from the dead), the deck doesn't have a strong spell slinger theme so her static doesnt work, the minus three is not as optimal as it makes itself out to be, and other effects are... not worth the six mana and time required.

Charcoal Diamond - You've got a ridiculous amount of ramp in this deck already, not sure this piece is needed. Plus, with the way K'rrik, Son of Yawgmoth works, you want to ramp in colourless more than in black with your artifacts and similar since K'rrik, Son of Yawgmoth always pays for black anyways, so Mind Stone just makes Charcoal Diamond look that much more of a downgrade.

Defense Grid - Not really seeing the point. Plus, this is meant to be a casual deck, all this will do is make everyone more upset and make interaction harder.

Saw in Half - It's a fun card not really worth adding.

Meathook Massacre 2 - I have a feeling it's a bit redundant to have both, especially since they both do a bit different things and you've got many tutors. Cutting the second part instead of its original installation would make more sense because this copy does cost a lot for its effect, whereas The Meathook Massacre became so played because it being pretty low costing for everything it does.

Paradise Plume - A lot of mana for its effect, and you have too many ramp cards.

Shared Trauma - Not too sure on this card's inclusion and what it would do.

Chain of Smog - I personally don't think discard cards are very strong in EDH, might be a good cut. I can see this being played against CEDH players and having a big effect, but EDH? Not as convinced.

Grim Tutor - You've got a lot of tutors, you can cut this one.

Final Parting - Same as above.

Diabolic Tutor - You can guess what I've got to say about this one.

Platinum Angel - I think take this one out. You can't pay life below zero so I'm not sure why else this would be in the deck.

Phage the Untouchable - As you said, you'd put it in your maybeboard and have it come out a game or two so you can just say you've killed someone with Phage, but I'd probably just keep it in the maybeboard.

Orcish Bowmasters - What are you playing, CEDH?

Opposition Agent - This is really more a meta suggestion than anything, but you don't verse people with a lot of tutors, you'd be lucky if people run more than one tutor. I'd cut this just from a meta perspective, or at least have it as a maybeboard card.

Doomsday Excruciator - Eh, nah.

Dimir House Guard - It's a sac outlet and a tutor in one, so I see what you're going with, which is why I'm only partially suggesting it as a cut, but also it's not the best at either job.

Chainer, Dementia Master - Not sure I'm feeling Chainer in this deck specifically.

Bloodletter of Aclazotz - Would be a lovely card for our cube, but I think there are already better finishers in this deck.

Asmodeus the Archfiend - Another maybe cut. It's a fun and spicy card, but also you're losing a lot of life for an effect which you do better with other cards in here. You really don't want to have too many cards that do similar things, especially since you've got many tutors and draw cards.

Cabal Stronghold - You've got three basic lands. There is no world in which you could activate this card and get a payoff from it.

Emergence Zone - Playing stuff at instant speed doesn't really help your deck.

Rogue's Passage - Zero use in this deck.

/

I also have addition suggestions:

Torment of Hailfire - Not sure why this isn't here.

Swamp - Add one Swamp for every land cut.

jsnrice on Atraxa, Grand Unifier

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.

Profet93 Playing the deck has been a very unique experience - having an open board most of the time and cards that accelerate the gameplan at the cost of life creates a glass cannon that either results in an instant win, or a suspenseful game where I'm hoping one piece of a combo doesn't get nuked off the table. My playgroup is wise to the deck's tricks by now, but I always manage to pull a surprise win every now and then at my LGS - the fun of having so many wincons! My biggest struggle with this deck has been balancing how fast I can get to my wins without tutors or less complex combos; the thrill of the setup is the real payoff. I've been considering swapping out Opposition Agent with something less oppressive, and possibly replacing Grave Betrayal with Matzalantli, the Great Door  Flip for that draw you mentioned. Thank you for your suggestions!

I have never seen a marelen deck without an Opposition Agent.

_Kane_ on Valgavoth, Harrower of souls (HF-1)

Hey, welcome to TappedOut.net! I would recommend listing you basic lands under one art image so the counts are more accurate. We can chat about the mana base another time.

Here are a few quick suggestions;

Sulfurous Springs - Replace Ash Barrens

Basilisk Collar - Lifelink to keep your HP at a healthy amount and deathtouch for a decent chump-blocker.

Razorkin Needlehead - Ping dmg on opp turns.

Blasphemous Edict - Board wipes are needed along with targeted removal.

Stormfist Crusader - Card draw

Roiling Vortex - This reads, "Yes, yes, and more please."

Scrawling Crawler - Yes, you have your opps drawing more cards, but they will pay for it with their life. You will also draw more cards. Taking advantage of the "symmetric" card draw by making it weighted in your favor.

Florian, Voldaren Scion - Card selection and Card draw.

Underworld Dreams - Ping dmg on opp turns.

Withering Torment - Enchantment removal is extremely rare in Rakdos Colors.

Ankh of Mishra - Ping dmg on opp turns.

Rug of Smothering - Ping dmg on opp turns.

Nightshade Harvester - Ping dmg on opp turns.

Magebane Lizard - Ping dmg on opp turns and keeps spell decks in check.

Cemetery Gatekeeper - Exile someone's fetch land from a GY. Then, whenever a player play a land you ping for 2 dmg.

Malakir Rebirth  Flip - A tapped land with a great spell on the backside.

Reanimate - Any graveyard...

I believe you opened a Bloodthirsty Conqueror!!

Expensive:

Sheoldred, the Apocalypse

Bloodchief Ascension

Orcish Bowmasters

Ob Nixilis, Captive Kingpin

Deflecting Swat

Jeska's Will

Deadly Rollick

Solphim, Mayhem Dominus

Zo-Zu the Punisher - I may have one of these for trade. I'll check.

Dauthi Voidwalker

Opposition Agent

As far a cuts:

Vile Entomber - Easy cut.

Olivia, Crimson Bride I would lose the graveyard reanimator subtheme.

Valgavoth's Lair - With your deck only being in two colors and with no add value for the land being an enchantment (the extra card type becomes more of a risk than reward), I would cut this land.

Enchanter's Bane - Just not strong enough and the damage isn't on your opponents turns.

Mask of Griselbrand - Too expensive to cast/equip and requires the creature to die for the card draw to trigger.

Temple of the False God - Easy cut. The pay off isn't there and the number of times you won't be able to tap this land for mana isn't worth the upside.

Light Up the Stage - There is better card draw.

Braids, Arisen Nightmare - The group slug effect is nice, but a potential cut due to being non-targeted removal/group sacrifice.

Massacre Girl - Black has better board wipes that can't miss.

Ash Barrens - Easy cut for a land more suited to your deck build.

Bloodfell Caves - Easy cut for a land more suited to your deck build.

Jund_Machinist on Breya, Doomsday Dominatrix

The main lines for the deck seem to be to either keep the Doomsdayfoil tech in or go with Underworld Breachfoil and a package that supports it. Cards I'm looking at include:

Brain Freeze to combo with Underworld Breachfoil and Lion's Eye Diamond, plus Wheel of Fortune etc.

Sevinne's Reclamation since it allows Intuition to directly tutor the previous combo in regardless of choice with Sevinne's, Underworld Breachfoil and Lion's Eye Diamond.

Final Fortunefoil seems really powerful.

Opposition Agent and Dauthi Voidwalker stronk.

Draw dorks: Ledger Shredder, Faerie Mastermind, Esper Sentinel, also Lotho, Corrupt Shirriff.

For more protection, Ranger-Captain of Eosfoil and Orcish Bowmasters

Ragavan, Nimble Pilferer seems meh unless in your opener.

Smothering Tithe cool, but 4 mana.

An Offer You Can't Refuse, Strix Serenade, Minor Misstep, Mindbreak Trapfoil, Dress Down

Thanks for all your suggesitons Profet93! I had Cabal Stronghold in another monoblack deck that's quite budget friendly, so I figured I'd try it out in here to see if it works instead of just sitting on the card.

I'm kind of surprised I don't have a Mind Stone in here lol. Maybe I'll try swapping it out for Arcane Signet because that added draw is very nice.

I mainly play 1v1 or at most a three person game since my playgroup is stretched thin and hard to get people, so while I initially had Syphon Mind when making the deck, it didn't feel that efficient since it never gets full 4 person value.

Lili is another one from the now budget deck that is more of a personal favorite card as its the first card I ever opened in a draft. It's probably not ideal aside from deck thinning. And I've never been big on Opposition Agent personally. I've been on the other end of it too many times and is more of a feels bad kind of card.

The current group I play with house ruled no The One Ring after our friend abused it in every single deck of his. It would be a house in this, but I'd rather keep the group happy and save myself 70 bucks that can go towards this foiling out project. I do have a friend that has a Beseech the Mirror for trades, so I can see about trying that if he's still got it!

ldvatwa +1

You don't have enough basics to reliably activate cabal stronghold. Perhaps swap it with Deserted Temple to untap coffers + politics or Thespian's Stage/Vesuva to copy coffer or other utility lands.

Mind Stone - Help ramp commander out on turn 3, and it is draw later when you don't need it.

MAYBE Syphon Mind - You draw 3, each opponent discards one.

Have you thought of swapping out Lili PW? Her +1 isn't impactful as with all your draw you're bound to get a swamp. Her second ability serves as okay removal. Perhaps for an Opposition Agent could prove more impactful given everyone searches in EDH. Whether its omni, creature or instant/sorcery tutors, or even fetchlands.

At the risk of being out of budget The One Ring might be a potential inclusion given it's a steady draw source and all your lifegain could mitigate it's downside. Maybe even a Beseech the Mirror to allow you to sacrifice it or just tutor in case you can't find what you're looking for with your draw.
