What bracket is my Commander deck?

Paste your list above and this calculator estimates its official Commander bracket (1 to 5) from the cards it contains. It reads the signals Wizards of the Coast uses to define brackets: the number of Game Changers, any cards banned in Commander, mass land denial, extra-turn chains, and two-card combos (using Commander Spellbook's full combo database). It maps those to a bracket, then shows the evidence so you can see exactly why.

One honest limit: no tool can read a deck's Bracket 5 (cEDH) intent from a list alone, because cEDH is about tournament tuning and a competitive metagame, not just card choices. So this calculator tops out its automatic reading at Bracket 4 and tells you when a deck could be pushed to cEDH.

What power level is my Commander deck?

Power level is the question, and the bracket is the modern answer to it. For years players guessed at an informal 1-10 number, which meant a "7" at one table was a "5" at the next. Wizards of the Coast replaced that guesswork with the official 1-5 brackets, built on criteria a decklist can actually be measured against. So this is a power level calculator: paste your list and it reads the cards, not your self-assessment.

If you still think in the old numbers, here is the rough translation. It is approximate on purpose, because brackets are set by concrete criteria rather than a single score.

Bracket Calculator FAQ

What bracket is my Commander deck?
Paste your decklist above and this tool estimates its official bracket (1 to 5) from the cards it contains. It flags Game Changers, banned cards, and two-card combos, then maps them to a bracket using Wizards of the Coast's published bracket criteria and Commander Spellbook's combo database.
What are the Commander brackets?
The official Commander bracket system has five tiers. Bracket 1 (Exhibition) is ultra-casual, Bracket 2 (Core) is an average precon-level deck, Bracket 3 (Upgraded) allows a few Game Changers, Bracket 4 (Optimized) has no restrictions, and Bracket 5 (cEDH) is tournament-tuned. Higher brackets allow more Game Changers, faster combos, mass land denial, and extra-turn chains.
How accurate is the bracket calculator?
The estimate reads real signals from your list: Game Changer count, banned cards, mass land denial, extra-turn chains, and Commander Spellbook's full two-card combo database. It cannot read intent or your local metagame, so it never claims Bracket 5 (cEDH) on its own. A deck it rates Bracket 4 may be cEDH depending on tuning and meta.
Does it detect combos?
Yes. It uses Commander Spellbook's combo database, so it catches two-card and turn-chaining combos that simpler counters miss. Matched combos are listed as evidence, tagged for locks, skipped turns, mass land denial, and extra turns.
What is a Game Changer?
Game Changers are the cards Wizards of the Coast flags as the most powerful in Commander. Running them pushes a deck into a higher bracket: Brackets 1 and 2 expect none, Bracket 3 allows up to three, and Brackets 4 and 5 have no limit. See our Game Changers list for the full set.
Is the bracket calculator free?
Yes, it is completely free with no account required. Paste a decklist and get an instant estimate.
Is this a Commander power level calculator?
Yes. Power level is the question; the bracket is the modern answer to it. The old 1-10 power level was an informal community guess, and Wizards of the Coast replaced it with the official 1-5 bracket system built on concrete criteria. This calculator reads your list against those criteria and returns a bracket, so pasting a decklist here is the fastest way to find out how powerful your EDH deck actually is.
What power level is my Commander deck?
Paste your list above. The calculator returns your deck's official bracket (1 to 5), which is the criteria-based replacement for the old 1-10 power scale. As a rough translation: power 1-4 is Bracket 1-2, power 5-7 is Bracket 3, power 8-9 is Bracket 4, and power 10 is Bracket 5 (cEDH). Brackets are defined by what is in your deck, not by a number you pick for yourself.
How strong is my Commander deck?
Strength in Commander comes down to four things a list can show: how many Game Changers you run, whether you have two-card infinite combos, whether you deny lands or chain extra turns, and how fast you can win. This calculator checks all four against Commander Spellbook's combo database and gives you a bracket plus the evidence behind it.
