If you've played Commander in the last year, you've heard someone ask "what bracket is your deck?" — and you've probably seen the table go quiet while everyone tries to guess. The bracket system is Wizards' attempt to give that awkward power-level chat a shared vocabulary. Here's what each of the five brackets actually means, in plain terms.
Why brackets exist at all
Commander is a casual format with a 1,000-plus card banlist's worth of variety, and "casual" means wildly different things from one table to the next. One person's fun is another person's miserable turn-four loss. Brackets don't rank players — they describe decks, so two strangers can find a game that feels fair without playing a round first to find out.
The five brackets run from gentle to ruthless:
Bracket 1 — Exhibition
The theme deck. You're here to show off a janky idea, not to win fast. No Game Changers, no mass land denial, no chaining extra turns, and no quick two-card combos. Games are slow and a little silly, and that's the point.
Bracket 2 — Core
The power level of a modern preconstructed deck straight out of the box. This is where most kitchen tables actually live. The same restrictions as Bracket 1 apply — no Game Changers, no land destruction strategies, no early combo kills — but the deck is more focused and the curve is cleaner. If you've upgraded a precon without adding raw power, you're still here.
Bracket 3 — Upgraded
The first "tuned" bracket. You can run a handful of cards from the Game Changers list, your mana is faster, and your win conditions are more reliable. Combos exist but tend to come together late rather than ending the game on turn five. Most "I built this myself and it's pretty good" decks land in Bracket 3.
Bracket 4 — Optimized
High power, no guardrails — short of the cEDH metagame. There's no list of banned-from-the-bracket cards here; you're building the strongest version of your idea and expecting opponents to do the same. The line between Bracket 3 and Bracket 4 is the one people argue about most, so it's worth understanding on its own.
Bracket 5 — cEDH
Competitive EDH. These decks are tuned against a living tournament metagame, play to win as efficiently as possible, and treat every card slot as a decision about that metagame — not about flavour. If you're not sure whether your deck is cEDH or just optimized, it's almost certainly the latter.
How to find your deck's bracket
You can eyeball it from the descriptions above, but the honest answer is that people are bad at rating their own decks — usually a bracket too low. That's the whole reason we built the analyzer: paste your list into the deck analyzer and it returns the official bracket with a card-by-card breakdown of what earned it. If you want the full ruleset behind those numbers, the methodology page lays out every rule we check and why.
Brackets aren't a leaderboard. They're a way to make the rule zero conversation take ten seconds instead of ten minutes — so you can get to the actual game.
