Commander Brackets Explained: The MTG 5-Bracket System (2026)

Updated

Commander brackets are Wizards of the Coast's official power level system for EDH. Every deck lands in one of five brackets, from Exhibition (1) to cEDH (5), and the bracket is the shared language for the pregame conversation: instead of arguing about what "a seven out of ten" means, you say "this is a bracket 3" and everyone at the table knows what to expect.

The system launched in beta in February 2025 and has been revised several times since. This guide covers what each bracket means today, which card choices force a deck up a bracket, what the Game Changers list actually is, and how to work out where your own deck sits.

If you just want the answer for your deck, the bracket checker is free and takes a decklist paste.

The five brackets at a glance

Bracket Name Expected win turn In one line
1 Exhibition 9 or later Theme first, winning a distant second
2 Core 8 or later A focused deck that plays fair Magic
3 Upgraded 6 or later Tuned, with real power spikes
4 Optimized 4 or later Everything legal, built to win fast
5 cEDH Any turn Tournament Magic in a 100-card shell

The turn expectations are not ours. WotC wrote them into the system in the October 2025 update: a Core deck should generally expect to play at least eight turns before the game ends, an Optimized deck at least four. That framing matters, because it makes speed part of the definition rather than an afterthought. A deck can pass every contents check for bracket 2 and still not be a bracket 2, because it wins too early.

Bracket 1: Exhibition

Exhibition decks are built around an idea, and the idea outranks winning. Every creature is a crab. Every card was printed the year you were born. The deck does something, and the something is the point.

WotC's guidance is that an Exhibition deck should have "fairly constrained and unique deck building", with Rule 0 flexibility for thematic choices that stretch the rules, like silver-bordered cards the table agrees to allow.

The common mistake is filing a deck here because it is cheap or weak. Bracket 1 is not the budget bracket. A pile of commons that ramps, draws, and eventually wins with a big attack is a functioning bracket 2, whatever it cost. Genuinely building a 1 on purpose is hard: it means a deck with no real win plan and nothing pushing the game to end, which almost nobody does by accident.

Bracket 2: Core

Core is the heart of casual Commander. The deck has a strategy and pursues it, the mana base works, and the game ends because somebody earned the win, usually from turn eight onward.

Contents-wise, a Core deck runs no Game Changers, no mass land destruction, no chained extra turns, and no two-card infinite combos. Those are the same restrictions as bracket 1; what separates the two is intent. A Core deck is trying to win. An Exhibition deck is trying to be something.

One thing Core is not, anymore, is "precon level". WotC decoupled preconstructed decks from bracket 2 in the October 2025 update, and the card data says why: precons vary enormously, and some ship contents whose official minimum bracket is 3 straight out of the box. We measured this across the official precon line: 19 of 142 precons carry an in-box two-card infinite combo or other contents that make bracket 2 impossible under the chart.

Bracket 3: Upgraded

Upgraded is where most invested players actually live. The deck has been tuned. The mana base is efficient, the card quality is high, and the deck threatens to win from around turn six.

The contents rules loosen here. An Upgraded deck can run up to three Game Changers, and two-card infinite combos are allowed, with the expectation that they close a game out late rather than end it on turn four. Mass land destruction and chained extra turns are still out.

In practice, one card choice puts more decks into bracket 3 than any other: a two-card infinite combo. If your deck can assemble two cards that loop for the win, it belongs at 3 or higher no matter how casual the other 97 cards are. Players are often surprised by this one, which is exactly what a checker is for.

Bracket 4: Optimized

Optimized removes the guardrails. Any number of Game Changers, combos wherever you want them, mass land destruction, extra turns, all of it. The deck is built to win and expects opposition that is too, with games that can realistically end by turn four or five.

The difference between a 4 and a 5 is not legality, since both can run anything. It is intent and consistency. A bracket 4 deck is a powerful deck. A bracket 5 deck is a tournament weapon.

Bracket 5: cEDH

cEDH is competitive Commander: decks built against the metagame, piloted to win through interaction, at tables where everyone agreed to that game. Wins come as early as the cards allow, and the deck is packed with free interaction and fast mana to make sure of it.

Bracket 5 should be hard to reach. If a checker calls your deck cEDH because it has a few strong staples, that is a miscalibration. A real 5 carries the current meta package, not just expensive cards. Most decks that feel strong at a kitchen table are 4s, and that is not an insult.

What are Game Changers?

The Game Changers list is WotC's list of legal cards that, in their words, easily and dramatically warp Commander games. Think of it as a power disclosure list, not a ban list. Every card on it is fully legal; running them just moves your deck up the bracket ladder.

As of the February 2026 update the list is 53 cards. The count per bracket is the rule:

The list itself has been revised repeatedly, which is worth knowing if you read older articles. The original February 2025 list had about 40 cards. April 2025 added more. October 2025 removed ten, including several big splashy spells and commanders like Kinnan and Yuriko whose power lives in the command zone, as the philosophy tightened from "strong card" to "warps the game". February 2026 added Farewell and Biorhythm, the latter coming straight off the ban list onto the Game Changers list.

So a deck that was legal for bracket 2 in early 2025 might not be today, and vice versa. Check against the current list, not a screenshot from launch week.

The contents floors: what forces a bracket

Four things set a hard minimum bracket no matter how the rest of the deck looks:

  1. Game Changer count. One Game Changer means bracket 3 minimum. Four or more means bracket 4 minimum.
  2. Two-card infinite combos. Any two-card infinite combo means bracket 3 minimum.
  3. Mass land destruction. Armageddon and friends mean bracket 4 minimum.
  4. Chained extra turns. Taking extra turns in a loop or long chain means bracket 4 minimum.

These are floors, not vibes. "It's a casual deck, the combo is just a backup plan" does not change the math; the chart reads the cards, not the intent. When we rate decks against their owners' self-assigned brackets, the single biggest source of disagreement is a floor the owner did not know about. Roughly a fifth of the decks we rate above their label carry contents whose official minimum already exceeds the label.

Tutors, notably, are no longer on this list. The original beta discouraged tutors at low brackets; the October 2025 update removed that restriction entirely. Tutors still make decks faster and more consistent, and speed feeds the bracket, but there is no tutor count that forces a bracket on its own.

Speed matters as much as contents

The contents floors are half the system. The other half is the turn expectations, and this is the half most bracket conversations skip.

WotC defines each bracket partly by when the game should end: turn nine or later for Exhibition, eight for Core, six for Upgraded, four for Optimized. A deck with zero Game Changers, zero combos, and a clean conscience that reliably wins on turn five is not a bracket 2 deck. It is faster than the bracket 2 social contract, and the table will feel it even if nobody can point at an offending card.

This is why counting Game Changers is not enough to bracket a deck, and why two decks with near-identical "bad card" counts can belong in different brackets. One of them is simply faster: better ramp, cheaper threats, a tighter curve. Any honest bracket rating has to estimate how quickly the deck actually threatens to win. That estimate is the hard part, and it is where checker quality is decided.

How to work out your deck's bracket

The manual version:

  1. Count your Game Changers against the current 53-card list. One or more means at least bracket 3. Four or more means at least bracket 4.
  2. Check for two-card infinite combos, including ones you did not build on purpose. Any hit means at least bracket 3.
  3. Check for mass land destruction and chained extra turns. Either means at least bracket 4.
  4. Then be honest about speed. If your goldfish wins arrive before turn six, you are looking at a 4. Before turn eight, a 3.

Steps 1 through 3 are lookups. Step 4 is the one humans are bad at, partly because nobody goldfishes their deck a thousand times and partly because "my deck is just a 2" is a table ritual older than the bracket system.

The checker does all four steps in a few seconds: it reads your list, applies the official floors, estimates a realistic win turn, and tells you the bracket with the reasons. Paste a decklist or drop a Moxfield, Archidekt, or Manabox link. Free, no signup.

Common bracket arguments, settled

"It's just a 2." Sometimes true. But bracket 2 has hard requirements, and a surprising number of self-rated 2s contain a Game Changer or an accidental infinite combo. If the deck also curves out fast, it is a 3 wearing a 2's name tag. Run the list through a checker before the argument, not after the game.

"Precons are bracket 2." Not since October 2025, and not before that either, really. WotC never assigned per-deck brackets to precons, and some ship bracket-3-minimum contents in the box. Treat each precon as its own deck.

"Bracket 1 is for cheap decks." Bracket 1 is for decks where the theme outranks winning. Budget is not a bracket. Most cheap decks are 2s.

"My deck has no Game Changers, so it's a 2." Contents floors are minimums, not maximums. Speed still counts. A lean, fast deck with a clean contents sheet can be a legitimate 3 or 4.

"Tutors make it a higher bracket." No tutor count forces a bracket since the October 2025 update. But tutors compress your win turn, and the win turn absolutely counts.

Bracket update history

The system is still marked beta, and it has moved. If you learned the rules once and stopped reading, here is what changed:

We track these changes as they land, because a bracket rating computed against last year's rules is quietly wrong. When WotC revises the chart or the list, the checker's rules update with it.

Brackets vs the old 1-10 power scale

Before brackets, Commander power talk ran on a 1-10 scale that meant nothing consistent. One player's 7 was another player's 4; the number had no definition, so every pregame conversation was two people trading private vocabularies.

Brackets fix the two worst parts. They have definitions, written down, that both players can read. And they have hard floors, so at least part of the placement is checkable against the actual cards rather than feelings. The 1-10 scale survives in older articles and some tools; if someone tells you their deck is a 7, the honest translation is "probably a 3 or a 4, let's find out".

How our checker rates a deck

Plenty of tools count Game Changers and stop. Counting is the easy half. The checker here enforces the official contents floors and then models the hard half: how fast the deck actually threatens to win, using the win-turn expectations WotC built into the system.

We also publish how well it works, measured on 3,585 real community-labeled Commander decks: 96.6% of ratings land within one bracket of the community's label, with the full per-bracket and per-source breakdown, including the cohorts where we look worst, on the accuracy page. The how and why of measuring bracket accuracy honestly, and what to ask of any tool that claims a number, is written up on the blog.

Frequently asked questions

What are Commander brackets?

Brackets are WotC's official five-tier power level system for Commander: 1 (Exhibition), 2 (Core), 3 (Upgraded), 4 (Optimized), and 5 (cEDH). Each bracket carries expectations about a deck's contents, like Game Changers and infinite combos, and about how fast the deck tries to win. They exist to make the pregame power conversation concrete.

Are Commander brackets official rules?

They are official guidance from Wizards of the Coast and the Commander Format Panel, currently in beta. Nothing about brackets is enforced in the rules engine; they are a tool for the pregame conversation, and Rule 0 still lets any table agree to anything.

How many Game Changers are there?

53 cards, as of the February 9, 2026 update, which added Farewell and Biorhythm. The list has changed several times since launch, so check the current list rather than an old article.

Can a precon be bracket 3?

Yes. WotC decoupled precons from bracket 2 in October 2025, and some precons ship two-card infinite combos or other bracket-3-minimum contents straight out of the box. Rate each precon as its own deck.

What bracket are most Commander decks?

The great majority of real decks are brackets 2 through 4, with bracket 3 the most common in our measured corpus. True bracket 1 decks are rare because ignoring winning takes deliberate effort, and true cEDH decks are rare because the bar is the current tournament meta, not just strong cards.

Do tutors raise my deck's bracket?

Not by count. The October 2025 update removed tutor restrictions entirely. But tutors make a deck faster and more consistent, and speed is part of every bracket's definition, so a tutor-dense deck usually rates higher for the honest reason.

What is the difference between bracket 4 and cEDH?

Both allow everything. Bracket 4 is a powerful deck built to win; bracket 5 is a deck built against the competitive metagame, with the fast mana and free interaction package that game demands, played at tables that opted into tournament-style Magic. Intent and consistency, not card legality.

How do I check my deck's bracket?

Paste your decklist into the free bracket checker, or drop a Moxfield, Archidekt, or Manabox link. You get the bracket in seconds with the reasons: Game Changers found, combos detected with their setup requirements, estimated win turn, and any contents floors that apply.
