Commander brackets explained: the five brackets, 1 to 5, each name what a deck is built to do and about how long a game should run, so a table can agree on an experience before the first turn. As of October 2026 they run from Bracket 1 (Exhibition) through Bracket 2 (Core), Bracket 3 (Upgraded) and Bracket 4 (Optimized) to Bracket 5 (cEDH), a scale the Commander Format Panel introduced on February 11, 2025 in Introducing Commander Brackets Beta. Bracket 2 is where most casual decks sit. A Core deck runs no cards from the Game Changers list, has no intentional two-card infinite combos and no mass land denial, plays extra-turn cards only in low quantities and never chains them, and expects games to last at least eight turns. The bracket is something you declare and talk through with your pod, not something a card count decides for you.
This guide covers the five brackets, exactly what Bracket 2 permits, how the Game Changers list works and how it has changed, how to have the pre-game conversation, and what the Mana Grove deck builder does to help you stay inside the bracket you chose. Everything about the rules below is quoted from the official announcements listed under Sources, with the dates we read them.
The five brackets, 1 to 5
The system is still labelled a beta by its authors, and it has been revised three times since launch. The current shape, per the October 21, 2025 update and the Commander format page at Wizards of the Coast:
| Bracket | Name | Game Changers allowed | What the deck is like | Games usually last |
|---|---|---|---|---|
| 1 | Exhibition | None | Prioritizes a goal, theme or idea over power; win conditions are highly thematic or substandard | At least nine turns |
| 2 | Core | None | Unoptimized and straightforward, with some cards chosen to maximize creativity; win conditions are incremental, telegraphed on the board and disruptable | At least eight turns |
| 3 | Upgraded | Up to three | Powered up with strong synergy and high card quality; Game Changers here tend to be value engines and game-ending spells | At least six turns |
| 4 | Optimized | No limit | Lethal, consistent and fast, designed to take people down as quickly as possible | At least four turns |
| 5 | cEDH | No limit | Meticulously designed for competitive play | Could end on any turn |
Brackets 1 to 3 are three levels of socially focused play. Brackets 4 and 5 are for higher-power and competitive play. Each bracket has an intent and philosophy behind it, which the Panel calls the most important part, and a short list of expectations on a few barometers: two-card infinite combos, extra turns and mass land denial.
To see what each bracket looks like in an actual list, read Commander decks by bracket.
What Bracket 2 (Core) permits
The launch article gave Core four deck-building guidelines, and three of them still stand:
- No cards from the Game Changers list. The official format page still states that Bracket 1 and 2 decks exclude Game Changers.
- No intentional two-card infinite combos, and no mass land denial. A Core deck should not be built to assemble two cards that end the game on the spot, and it should not destroy or lock down everyone's lands.
- Extra-turn cards only in low quantities, and never chained in succession or looped.
- Tutors should be sparse was the fourth guideline. The October 21, 2025 update removed the tutor restriction from the brackets entirely, relying on the Game Changers list to catch the most efficient tutors instead. A Core deck can run tutors, as long as none of them is a Game Changer.
Two other things changed in October 2025. The launch article had described the average current preconstructed deck as a Core-level deck; the Panel removed that anchor, because older precons cannot keep up with modern ones and some modern precons fit Bracket 3 better. And the bracket descriptions were rewritten around expectations, including the turn counts in the table above, rather than only around card restrictions. The February 9, 2026 update made no change to the brackets themselves and said the beta tag will likely be dropped later this year if the Panel stays happy with the current shape. As of October 2026 no bracket update has followed it, so the table above still shows the current shape.
In practice, a Bracket 2 deck is a deck you built to do its thing and win in the late game, with the wins visible on the board before they happen. If a single card in your list makes an opponent groan when it resolves, check whether it is a Game Changer.
Game Changers: the list behind the brackets
Game Changers are cards the Panel judged to dramatically warp a Commander game: they run away with resources, shift the game in ways many players dislike, lock people out of playing, or find the strongest cards too efficiently. The list is the mechanical part of the system: zero Game Changers in Brackets 1 and 2, up to three in Bracket 3, no limit in Brackets 4 and 5.
Six examples from the current list, with what they do:
- Rhystic Study, {2}{U}: whenever an opponent casts a spell, you may draw a card unless that player pays {1}. In a four-player game that is a card on most turns.
- Cyclonic Rift, {1}{U}: returns one nonland permanent you do not control to its owner's hand, or with overload ({6}{U}) every one of them, at instant speed.
- Demonic Tutor, {1}{B}: searches your library for any card and puts it into your hand.
- Smothering Tithe, {3}{W}: whenever an opponent draws a card, you create a Treasure token unless they pay {2}.
- Thassa's Oracle, {U}{U}: when it enters, you win the game if your devotion to blue is at least the number of cards left in your library.
- The One Ring, {4}: gives you protection from everything until your next turn when you cast it, then draws more cards every turn.
The list has moved with each update. It launched with 40 cards on February 11, 2025. The April 22, 2025 update removed Trouble in Pairs and Trinisphere and added a larger batch, including Teferi's Protection, Humility, Necropotence, Orcish Bowmasters, Worldly Tutor, Natural Order, Field of the Dead and Mishra's Workshop. The October 21, 2025 update removed ten cards, among them Expropriate, Vorinclex, Voice of Hunger, Kinnan, Bonder Prodigy, Urza, Lord High Artificer, Winota, Joiner of Forces and Yuriko, the Tiger's Shadow, so the Game Changer rule no longer keeps them out of a Bracket 2 deck. The February 9, 2026 update added Farewell and Biorhythm. Our card database, which follows the official list, flags 53 cards after that update. Check the official format page for the full, current list rather than a memory of it.
To count the Game Changers in a list you already have, paste it into the Commander bracket checker, no account needed. How the bracket checker reads a deck explains what else it looks for, and why it never answers Bracket 1 or Bracket 5.
How to tell your pod which bracket you are on
The pre-game conversation is the point of the system. Before the first shuffle, each player says which bracket their deck is, and the table agrees on whether that is a game they all want. The official format page puts it simply: in your pregame conversation, you can ask what bracket people's decks are.
Say the number and any exceptions in one sentence. The launch article's own example is: "I'm in Bracket 2, except for this one thing. Is that okay with everybody?" That keeps the Rule Zero conversation intact: the brackets are a shared vocabulary, not a substitute for asking. If your Core deck has one card that arguably pushes it, name the card, and let the table decide.
How the Mana Grove deck builder helps
The deck builder cannot tell you what your pod enjoys, but it can do the counting and the checking:
- Legality first. Legality checks run as you build, against the Commander rules, and the Validation tab holds the full report: deck size, copy limits, the commander itself and colour identity. A bracket conversation about an illegal deck is a short one. See Deck Builder Basics.
- A target bracket and bracket signals. Set a Target bracket on your deck and the Bracket signals panel assesses the list against it: it counts the Game Changers in the deck and flags the signals the brackets care about, such as mass land denial, extra turns, fast mana and tutors, marking each one as informational or as raising the deck's bracket. The panel tells you what the list assesses to, and whether that meets, sits under or lands above your target. The bracket you declare is still yours; the assessment is a helper, not a referee.
- Search that respects the bracket. When you add cards with Scry, our AI-powered card search, you can bias results toward your Commander bracket or show only Game Changers, which is the quickest way to audit a list you have been handed. Those two filters need Scry; classic keyword results show without them.
- A first draft that starts in the right bracket. If you are building from scratch, tell Grover, our AI deck assistant, the bracket in the brief ("Bracket 2, no infinite combos") and set the deck builder's Target bracket to the same value, which sends it to Grover with the build. Then check the result with the signals panel. How to build a Commander deck with an AI assistant walks through it.
Frequently asked questions
Is Bracket 2 the same as a precon?
Not any more. The launch article used the average current precon as the reference point for Core, and the October 21, 2025 update removed that link because precons vary too much: some older ones play like Bracket 1, and some newer ones play like Bracket 3. Judge a precon by the table above, not by the box.
What is the most common Commander bracket?
No official figure exists in the sources this page cites: the format page and the bracket updates under Sources define the brackets, and none of them counts how many decks sit in each. The October 21, 2025 update says the Panel expects Brackets 2, 3 and 4 to be the most popular, without giving a count. What we can measure is the precons. All eleven 2026 Commander precons ranked in our precon guide read as Bracket 2 (Core) in our checker, and none of them contains a Game Changer. Since the October 21, 2025 update a precon is no longer the official reference point for any bracket, so read that as a fact about those eleven decks, not about every deck at every table.
Can a Bracket 2 deck run tutors?
Yes, since the October 21, 2025 update removed the tutor restriction. The efficient tutors that the Panel considers game-warping, such as Demonic Tutor, are on the Game Changers list, so a Core deck cannot run those. Other tutors are fine.
Can a Bracket 2 deck run any extra-turn cards?
A few, played as single extra turns. The guideline is low quantities, and never chained in succession or looped. A deck built to take three turns in a row is not a Core deck.
How many Game Changers can I play in Bracket 3?
Up to three. Brackets 4 and 5 have no limit, and Brackets 1 and 2 have none at all.
Who decides my deck's bracket?
You do, and your pod agrees or negotiates. The Game Changers list and the barometers are there to make that conversation honest and short. The deck builder's bracket signals show you what the list looks like from the outside, so you can answer the question before it is asked.
