Commander Brackets Explained: The 1–5 Power Level System

3 min read Updated Aug 10, 2026

Commander brackets are a 1–5 scale for describing how strong an EDH deck is before the game starts. Here is what each bracket means, which cards move a deck up, and why Bracket 5 works differently from the other four.

Commander brackets are a 1–5 scale for describing how strong an EDH deck is, so a pod can agree on the kind of game it wants before anyone shuffles. They are a conversation tool, not a rule.

The five brackets

Bracket 1 — Exhibition. Built around a theme or a bit rather than around winning — little to no tutoring, fast mana or interaction.

Bracket 2 — Core. Precon-level power. Some strong cards, no fast combos — the deck most tables expect.

Bracket 3 — Upgraded. Tuned mana and real win conditions, with up to three Game Changers allowed.

Bracket 4 — Optimized. High power, efficient interaction, compact win conditions.

Bracket 5 — cEDH. Playing to win against a competitive metagame.

What moves a deck up a bracket

Five card-based rules set the top of the scale:

Game Changers — a curated list of especially powerful Commander cards. Running one to three generally places a deck at Bracket 3. Four or more places it at Bracket 4.
Two-card combos — a combo that wins with two pieces puts a deck at Bracket 3.
Mass land denial — Armageddon effects and the combos that produce them push a deck to Bracket 4.
Lock combos, and combos that take control of every opponent, also mean Bracket 4.
Extra turns — extra-turn effects keep a deck out of Bracket 1.

What separates Bracket 1 from Bracket 2

Those five rules only ever push a deck up, and none of them draws the line between Bracket 1 and Bracket 2 — because that line is not about cards. It is about whether the deck is trying to win at all.

Bracket 2 is the default: the average deck, roughly what a precon plays like. Bracket 1 is the exception, and it looks like one — a high curve, no tutors, no fast mana, little interaction and no expensive staples. A deck is Exhibition because it was built that way on purpose, not because it happens to be missing a Game Changer.

The same evidence reads upward. Heavy tutoring, several pieces of fast mana, free interaction, a low curve or dense removal will put a deck at Bracket 3 with no Game Changers in it at all.

Bracket 5 is about intent, not cards

Brackets 4 and 5 allow exactly the same cards, so no decklist can prove which one it is. The difference is whether you are playing to win against a competitive metagame. A deck can be measured up to Bracket 4; Bracket 5 is something the pilot declares.

Signals that usually travel with cEDH are measurable, though — a low average mana value, several pieces of fast mana, unrestricted tutors, free interaction, a low land count and compact combos.

You cannot cut your way to the bottom

Cutting cards only removes what the bracket rules single out. Strip the Game Changers and combos out of a highly tuned Bracket 4 deck and it does not become an Exhibition deck — the tutoring, mana and interaction are all still there, so it lands at Bracket 3. Going below that means rebuilding, not trimming.

Checking a decklist

The Commander Bracket Calculator takes a decklist and reports its bracket along with the specific cards responsible. It is public and needs no account.

The standalone Combo Finder covers the combos side in more detail, including which combos in a list are two-card.
