Use this infographic to understand the Bracket system and to guide pre-game conversations about game expectations and player intent.
per the latest WotC guidelines
Theme Over Power
Decks prioritize a goal, theme, or idea over power. Card choices serve the concept, not the metagame.
Highly thematic or suboptimal. Usually slow, telegraphed, and easy to interact with.
Creativity & Entertainment
Mechanically focused card choices that maximize creativity and fun over raw efficiency.
Incremental and telegraphed on the board. Disruptable by most decks.
Synergy & Quality
Powered up with strong synergy and high card quality. Up to three Game Changers are allowed.
Can close games from hand in one turn, but game-ending combos should not occur during the first six turns.
Lethal & Consistent
Lethal and consistent. No bracket restrictions on Game Changers, land denial, combos, or extra turns.
Vary by archetype but are efficient and instantaneous, backed by powerful interaction.
Meticulous & Strategic
Meticulously designed for the cEDH metagame. Every card slot is optimized for efficiency.
Optimized for speed and consistency. Wins are fast, efficient, and demand specific answers.
Game Changers are a curated list of high-impact cards maintained by the Commander Format Panel that dramatically warp casual games.

DeckCheck offers the most accurate bracket checker around. Create or Import your deck list and scan it to get an accurate and detailed bracket analysis like the example below.
Commander Brackets are the official five-level framework created by Magic’s Commander Format Panel and Wizards of the Coast to help players communicate deck strength and gameplay expectations before a game. They provide shared language for a Rule 0 conversation rather than creating five separate formats.
DeckCheck checks the complete decklist against the current bracket restrictions (Game Changers, mass land denial, extra turns, and two-card infinite combos). It then rates the deck with the DeckCheck Threat Index, which scores 12 benchmarks across resources, access, pressure, interaction, and resilience. A deck that rates above its card restrictions moves up to the bracket its Threat Index reaches. The result includes a detailed explanation instead of only a number.
No. Brackets give players a useful starting point and a shared vocabulary, but they cannot describe every deck or playgroup preference. Players should still discuss unusual strategies, commanders, house rules, and the kind of game everyone wants before starting.
No. Traditional 1–10 power ratings are subjective and often leave most decks clustered around the same numbers. Commander Brackets use five named categories with concrete deckbuilding restrictions, turn expectations, and play mindsets, making pregame comparisons more specific.
No. Commander’s banned list determines format legality. Bracket restrictions describe the experience expected within a particular bracket, and a playgroup can agree to make exceptions during its Rule 0 conversation.
Treat the highest-bracket deck as an important warning that the game may be mismatched. Players can switch decks, agree to play at the higher expectation, or discuss specific concessions before the game so everyone knowingly accepts the difference.
