Commander brackets and Game Changers explained

Updated September 27, 2026 · Commandarium

What are Commander brackets?

Commander brackets are the official power level system for Magic: The Gathering’s Commander format. Wizards of the Coast introduced them in 2025: five brackets from casual to competitive, meant to be discussed before a game starts so that decks of similar strength play each other.

The five brackets

How do Commander brackets work?

Each bracket describes what a deck is expected to do and which kinds of cards fit in it. Three things decide where a deck lands:

• Game Changers — a short list of especially powerful cards (see below), limited per bracket.
• Specific strategies — mass land destruction, chaining extra turns and two-card infinite combos are not expected in the lower brackets.
• Intent — how fast and how reliably the deck wants to win. Only you can tell your table that.

Before the game, everyone names the bracket of their deck. If the brackets are far apart, someone switches decks — that is the whole point.

What is a Game Changer?

Game Changers are cards that shift a game far more than an average card — they generate overwhelming resources, shut opponents out, or win out of nowhere. Typical examples are extremely efficient tutors, free or near-free powerful spells, and cards that draw huge numbers of cards for little effort.

The list is maintained by Wizards of the Coast and changes from time to time. The current list is always searchable on Scryfall with is:gamechanger.

How many Game Changers per bracket?

• Brackets 1 and 2: none.
• Bracket 3: up to three.
• Brackets 4 and 5: no limit.

Brackets and the old power level scale

Before brackets, Commander players rated decks on an informal power level scale from 1 to 10. It never had fixed definitions, so one table’s “7” was another’s “9” — the running joke is that every deck is a 7. Brackets replace the vague number with concrete criteria: named cards and named strategies.

Still, Game Changers are only one part of a bracket. A deck without a single Game Changer can be far stronger than a precon, and the most important part remains the conversation: tell your table what your deck does and how fast it wants to win.

Rule of thumb: brackets are a starting point for the pre-game talk, not a rating the deck earns automatically.

What bracket is my deck?

1. Count your Game Changers. None keeps Bracket 1 or 2 possible; one to three means Bracket 3 at least; four or more means Bracket 4 or 5.
2. Check the strategies. Mass land destruction, chained extra turns and two-card infinite combos are restricted in the lower brackets — if your deck relies on them, check the current guidelines.
3. Compare with a precon. A typical preconstructed deck is the benchmark for Bracket 2. A deck that clearly outperforms one belongs in Bracket 3 or higher, Game Changers or not.
4. Be honest about intent. A deck built to win as fast as possible is Bracket 4 or 5, whatever its card list says.

In Commandarium, every deck counts its Game Changers and shows the bracket range that count points to: none → Bracket 1–2 range, one to three → Bracket 3 range, four or more → Bracket 4–5 range. The number turns into a warning once it passes three, so a deck meant for a casual table doesn’t drift up by accident. Build a deck with the Commander deck builder or import your list to see it.
