Hello everyone! I’m Levi from The Thought Vessel, and today I want to talk about combos. Commander allows players to build decks and archetypes that don't really get a chance to shine in other formats. That includes plenty of combos that aren't powerful enough for sixty-card formats or cEDH but can have a home in Commander. It's an opportunity to use cards from across every era of Magic to see what kind of busted things players can come up with. But to make sure we set our expectations here, let’s take a look at what the Bracket system has to say about combos.

October 2025's revised Commander Brackets infographic.

What the Bracket System Says About Combos

Starting with Bracket 1, there is a hard and fast restriction on two-card infinite combos. Since this is an incredibly laid back style of play that expects players to have at least nine turns, I wouldn’t recommend playing combos here at all.

Bracket 2 also has a restriction on two-card infinite combos and it also states that win conditions should be incremental, telegraphed on the board, and disrupt-able. This is directly in conflict with most combos as they can win a game quite abruptly if players aren’t ready for them. I would be cautious about using combos here as well.

Starting at Bracket 3, we start having more of an open conversation about combos. In this bracket, two-card infinite combos are allowed if they take place after turn six. A combo like Mikaeus, the UnhallowedMikaeus, the Unhallowed, and TriskelionTriskelion that can deliver infinite damage to the board typically is fine in Bracket 3 since it requires us to play six mana creatures either over multiple turns and risk removal, or at the same time. Of course, deck construction plays a big part in this too, as a card like Defense of the HeartDefense of the Heart can change the math quite a bit, but we’ll talk more about this later.

Another note here is that none of these brackets make any mention of combos that use three cards or more. These are deemed acceptable at every bracket, which shifts the focus back to the intention of the deck. the Bracket system isn't trying to eliminate combos. Instead, it's encouraging players to think about how consistently they can assemble them and how early they can realistically end a game.

Bracket 4 and 5 both fully allow combos, with bracket 5 adding the question of viability into the conversation. Bracket 4 is a good home for both Combo and Stax decks since there really isn’t much room for those playstyles elsewhere in the Bracket system.

There is the factor of Rule Zero that we have to take into account as well. Some players simply don’t enjoy playing against combos regardless of what the brackets say. While our deck might be right for the bracket, it may be wrong for the pod. If that's the case, it's usually easier to grab another deck or find a different pod than force a game nobody wants. At the same time, if players are intentionally taking advantage of not having to worry about combos and building their decks accordingly, that isn’t cool either. At that point, it may simply be best to find a different pod altogether.

When we do look to add a combo to our deck, the goal should be for it to be an enjoyable part of the deck instead of an "I win" button. There are different degrees to the importance of a combo within a deck, but most combos fall into one of two different categories: Organic Combos and Inorganic Combos.

Organic vs. Inorganic Combos

Organic combos are made up of cards that the deck already wants to play on their own. A gold standard for an organic combo is GravecrawlerGravecrawler and Phyrexian AltarPhyrexian Altar in a Zombie typal deck.

Gravecrawler can be cast from the graveyard as long as we control a Zombie, and Phyrexian Altar is one of the premier sacrifice outlets in the format. With a deck like Zombies, sacrificing creatures and bringing them back from the graveyard is already one of the core themes regardless of the commander since Zombies are naturally good at it. Both of these cards work incredibly well with that strategy, and we would almost have to go out of our way to exclude one of them just to avoid creating a combo.

Notably, this is considered an early game combo by the greater EDHREC community, so if we wanted to put this into a Bracket 3 deck, it is something we should bring up before the game to make sure everyone is comfortable with it. If they aren't, the beauty of an organic combo is that we can still play the deck and use both cards independently. In my experience, if I explain that I'm playing an organic combo, players who aren't comfortable with the combo are still perfectly fine with me playing the deck as long as I don't intentionally assemble it. I can just use the synergy of the deck to focus on combat or whatever my Plan A is. 

Inorganic combos are built from cards that the deck normally wouldn't be interested in playing on their own. The most common example is the classic Thoracle combo made up of Thassa's OracleThassa's Oracle and Demonic ConsultationDemonic Consultation. This combo puts Thassa's Oracle onto the stack while exiling the rest of our library, resulting in an immediate win. It's incredibly fast, incredibly efficient, and sees frequent play in cEDH.

Another example is Exquisite BloodExquisite Blood and Sanguine BondSanguine Bond, which loop life gain and life loss back and forth until the rest of the table has been drained out of the game. While both cards are individually playable, adding them to something like an Enchantress deck or a Reanimator deck usually isn't the best use of those card slots. Yes, if we assemble the combo we win the game, but individually they don't contribute nearly as much to the primary game plan. They're also some of the most recognizable combo pieces in Commander, so casting one by itself often attracts unwanted attention. Decks playing inorganic combos are generally better off making the combo their Plan A instead of treating it like a backup win condition.

Combo Decks vs. a Deck with a Combo

With combos, we have the option of making them the primary focus of the deck or simply using them as an alternate win condition.

In the example of GravecrawlerGravecrawler and Phyrexian AltarPhyrexian Altar, we have a chance of playing the combo in Bracket 3 if we have a discussion with the table beforehand. If that same Zombie typal deck has ten tutors and can consistently assemble the combo every game, that starts looking much more like a Combo deck playing an early game combo and should probably move into bracket 4 instead. If we're simply drawing cards naturally and happen to assemble the combo over the course of a game, the chances of actually winning with it are much lower.

Instead, the combo becomes another angle of attack when our primary strategy stops working. It gives us an answer when something has completely shut down our original game plan, whether that's repeated FogFog effects stopping our combat deck or Rest in PeaceRest in Peace locking down our graveyard strategy.

Having another way to win takes the game from "Well, I guess I'm out" to "Alright, onto Plan B." One of the most frustrating parts of Magic is being in a game where we simply can't do anything. By adding a combo to our deck, we're never completely out of the game, and there's always the chance to topdeck into something that changes everything.

A Combo deck specifically has to be much more intentional with the supporting pieces around it. If we build a Combo deck for Frodo, Adventurous HobbitFrodo, Adventurous Hobbit and Sam, Loyal AttendantSam, Loyal Attendant using Samwise GamgeeSamwise Gamgee, Cauldron FamiliarCauldron Familiar, and Carrion FeederCarrion Feeder, that could still fit comfortably into Bracket 3 because it requires three cards and is very interactable. If players know they're sitting down against a Combo deck, it won't feel like a betrayal or come as a surprise if we eventually assemble it because the expectation has already been established.

The biggest factor in determining a Combo deck's power level isn't necessarily the combo itself. It's how consistently the deck can assemble it. A deck with ten tutors that regularly finds the same two-cards by turn five is going to play much differently than one that has to naturally draw into all of its pieces. Godo, Bandit WarlordGodo, Bandit Warlord is a perfect example of this. Even though Godo isn't as popular in cEDH as it once was, the deck has an incredibly consistent game plan. Every game revolves around ramping to eleven mana, casting Godo, tutoring up Helm of the HostHelm of the Host, and generating infinite combat steps. All we have to do is get to eleven mana and cast our commander. 

How I Personally Use Combos

Looking through my current collection of Commander decks, I have five decks that use combos in very different ways. Some decks are built around their combos, while others simply have them by accident... literally. Allow me to explain.

Starting off is my Malcolm, Keen-Eyed NavigatorMalcolm, Keen-Eyed Navigator and Sakashima of a Thousand FacesSakashima of a Thousand Faces deck that wants to clone Malcolm as many times as possible to build up a Treasure pile that would make Fort Knox jealous. The combo in this deck involves Hullbreaker HorrorHullbreaker Horror and Sol RingSol Ring. With a couple of cheap mana rocks, I can bounce them back and forth to generate infinite mana.

The funny part is that the deck doesn't actually have a payoff for infinite mana. I don't have Walking BallistaWalking Ballista or anything like that. If I happen to make infinite mana, great. If not, the deck is still doing exactly what it was built to do by making treasure and overwhelming the table with value. The combo is simply something the deck can do randomly.

The next deck is my Breya, Etherium ShaperBreya, Etherium Shaper deck that is built around one of my favorite combos ever, Thopter FoundryThopter Foundry and Sword of the MeekSword of the Meek. With both of these cards in play, we can spend one mana to make a 1/1 Thopter token with flying and gain one life. We can do this for every mana we have available. While I don't play Time Sieve to take infinite turns, I can pair the combo with Ashnod's AltarAshnod's Altar or Urza, Lord High ArtificerUrza, Lord High Artificer to make infinite mana to fill the skies with Thopters. Honestly though, I'm just as happy making five or ten Thopters every turn and trying to win through combat. I just enjoy playing those two-cards together.

My Eddie BrockEddie Brock deck uses the combination of Mikaeus, the UnhallowedMikaeus, the Unhallowed and TriskelionTriskelion as an inorganic combo. While neither card is a perfect fit for the deck, the combo serves an important purpose by giving me a way to end the game if things start going sideways. My list is playing huge creatures like Ghalta, Primal HungerGhalta, Primal Hunger, and we're aggressively digging through the deck to generate as much value as possible. The downside is that we can burn through our library surprisingly quickly. I can't simply throw Laboratory ManiacLaboratory Maniac into the deck, so I need another way to finish the game before I accidentally deck myself.

My bracket 4 Alexios, Deimos of KosmosAlexios, Deimos of Kosmos deck uses Godo, Bandit WarlordGodo, Bandit Warlord together with Helm of the HostHelm of the Host. Both cards are excellent individually in Alexios. Godo can tutor up whatever equipment we need while Helm of the Host keeps making additional copies of Alexios to flood the battlefield with complete combat chaos. If Alexios stops being effective later in the game, putting the two-cards together gives us infinite combat steps to close things out. I'm not trying to win through Godo every game. It's simply another plan when everything else has gone wrong.

Finally, my beloved Brago, King EternalBrago, King Eternal deck plays several different combos, but the most consistent one involves Brago's triggered ability, Strionic ResonatorStrionic Resonator, and at least two mana from blinkable mana rocks. By blinking both the Resonator and our mana rocks, we can repeatedly trigger Brago and loop nearly every enters the battlefield effect we have in play. We can draw our entire deck, make infinite creature tokens, or even raise a glass to the table with Hierophant's ChaliceHierophant's Chalice.

Unlike my other decks, this one is absolutely a dedicated Combo deck and firmly belongs in bracket 4. Combat victories really aren't a realistic option, so the deck is packed with protection, interaction, tutors, and contingency plans to make sure it can eventually assemble one of its combo lines. Combo is Plan A, B, and C.

Wrapping Up

Combos aren’t inherently competitive or casual. They’re simply another tool in deckbuilding. The biggest danger is letting them become more of a focus than we actually want them to be. What determines whether a combo belongs in our deck isn't just how many cards it requires, but how consistently we can assemble it, how our deck finds those pieces, and whether our table expects it.

While our deck might be right for the bracket, it may be wrong for the pod. That is okay.

Commander has always been a social format first, and Rule Zero exists to help everyone have the kind of game they're looking for. Some groups love trying to stop a combo before it comes together, while others would rather spend their evening watching huge creatures crash into each other. Neither approach is wrong. The important part is making sure everyone is sitting down with the same expectations.

If your deck is capable of reliably assembling a combo, let your table know before the game starts. Setting expectations goes a long way toward creating better Commander games. Your opponents will probably pay a little more attention to you during the game, but that's a fair trade for playing a deck that can win out of nowhere. More often than not, you'll find that players appreciate the honesty, and you'll have a much better game because everyone knew what they were signing up for.

Whether your combo is an organic interaction that your deck naturally stumbled into, or the centerpiece of your entire strategy, remember that the goal is to create fun and memorable games, not simply end them as quickly as possible. Until next time, happy brewing.
