MTG Commander brackets explained: the five brackets, what Game Changers are, how to work out your deck's bracket and how to use brackets in a pre-game chat.
Commander is a casual format with an enormous range of deck power, from a lightly tweaked precon to a finely tuned competitive list. The bracket system was introduced to give players a shared language for that range, so a table can agree what kind of game it wants before anyone shuffles up. It does not replace a conversation; it makes the conversation quicker.
The short answer: there are five brackets, from 1 (Exhibition) to 5 (cEDH). Count the cards in your deck that appear on the official Game Changers list, check for mass land denial, chained extra turns and early two-card infinite combos, and consider how fast the deck aims to win. No Game Changers and none of those features usually means bracket 1 or 2; up to three Game Changers is bracket 3; anything beyond is 4 or 5.
What are Commander brackets?
Brackets are a five-level scale published by Wizards of the Coast with the Commander Format Panel to describe how powerful a deck is. They are a guide for pre-game discussion, not a rule that decides who may play with whom. Think of them as a quick shorthand for the Rule Zero chat.
What are the five brackets?
Each bracket describes the kind of experience a deck is built for. The summary below is simplified; check the official bracket page for current details.
| Bracket | Name | Game Changers | Typical feel |
|---|---|---|---|
| 1 | Exhibition | None | Theme first; winning is secondary |
| 2 | Core | None | Roughly the power of a modern precon; long, interactive games |
| 3 | Upgraded | Up to 3 | Tuned, stronger synergies; no early infinite combos |
| 4 | Optimised | No limit | High power, anything legal goes |
| 5 | cEDH | No limit | Competitive, built to win as fast as possible |
What are Game Changers?
Game Changers are an official list of cards that have an outsized effect on games, such as powerful tutors, fast mana and cards that generate overwhelming advantage. They are legal in every bracket, but including any of them pushes a deck to at least bracket 3. The list is reviewed periodically, so check the current version before an event.
How do you work out which bracket your deck is in?
Start with intent: are you building around a theme or trying to win as efficiently as possible? Then count Game Changers, and check for mass land denial, chained extra turns and two-card infinite combos that can win early. Those features move a deck up regardless of the card count.
What bracket are preconstructed decks?
Most recent preconstructed Commander decks are designed to sit around bracket 2, which is why that bracket is often described as precon level. A precon that includes a Game Changer would technically sit at 3. Once you upgrade a precon, recheck where it lands.
Are brackets official rules?
No. They are guidance for matching decks, not a banned list; the Commander banned list is separate. A playgroup can still agree to anything it likes, and bracket labels work best alongside a quick description of what your deck does.
Have the bracket rules changed since launch?
Yes, a few times. The Game Changers list has had cards added and removed, and some early restrictions, such as the general limit on tutors, were later dropped. Treat any summary, including this one, as a starting point and check the official announcement before a tournament or store event.
Do higher brackets mean shorter games?
Generally, yes. Higher-bracket decks are built to win sooner, while bracket 1 and 2 games tend to run longer with more back-and-forth. Our guide to how long a Commander game takes has tips for keeping any bracket moving.
How do you keep track of several decks at different brackets?
Label them. A simple sticker with the bracket number inside the lid, or a different colour of deck box per bracket, means you grab the right deck for the table. See how to tell your Commander decks apart for more ideas.
