Commander Brackets Explained

What Are Commander Brackets?

Commander Brackets are the official power-level framework introduced by the Commander Format Panel and Wizards of the Coast in 2025. They provide a shared language for players to communicate deck power levels before a game starts, replacing the often-confusing 1-10 scale that meant different things to different players.

The system uses five numbered brackets that range from casual theme decks to fully competitive cEDH builds. Each bracket defines clear expectations about card choices, game pace, and strategic complexity, making pregame conversations faster and more productive.

The Five Brackets

What Are Game Changers?

Game Changers are a curated list of cards that Wizards of the Coast has identified as significantly impacting the Commander format. The list launched with 40 cards and is regularly reviewed and updated as the format evolves. These cards are powerful enough that their presence or absence meaningfully changes the power level of a deck.

Examples include fast mana like Mana Vault and Grim Monolith, powerful tutors like Demonic Tutor and Vampiric Tutor, and game-warping effects like Rhystic Study and Smothering Tithe. The full list is maintained by WotC and updated periodically.

The bracket system uses game changers as an objective measure of power level. Brackets 1 and 2 exclude all game changers. Bracket 3 allows up to 3. Bracket 4 has no restrictions. This creates clear, enforceable power level boundaries.

Combo Restrictions by Bracket

In addition to game changer limits, brackets define rules around two-card infinite combos. These are card combinations where two cards together create an infinite loop (infinite damage, infinite mana, infinite tokens, etc.) or an instant win condition.

Brackets 1 and 2 do not allow intentional two-card infinite combos. Bracket 3 allows them as long as they cannot happen cheaply in the first six or so turns of the game. Late-game combos that require significant mana investment are acceptable at Bracket 3. Brackets 4 and 5 have no combo restrictions.

When building on Spellweave, the deck engine automatically enforces these combo restrictions based on your selected bracket. If a two-card infinite combo would violate your bracket’s rules, the engine will avoid including both pieces in the same deck.

Choosing Your Bracket

If you’re new to Commander, start with Bracket 2. Most precons are Bracket 2, and it’s the most common starting point for new players. As you build your collection and want stronger decks, move to Bracket 3.

The best bracket is the one your playgroup agrees on. Before each game, have a quick conversation about brackets. If everyone is at Bracket 2, everyone has a good time. If one player is at Bracket 4 and everyone else is at 2, that’s a mismatch that leads to unfun games.

When building on Spellweave, select your target bracket and the engine will automatically respect both game changer and combo restrictions. This guarantees your deck is bracket-compliant before you sit down to play.

Commander Deck Building Basics

Commander (also known as EDH) is a multiplayer format where each player builds a 100-card singleton deck led by a legendary creature as their commander. Your deck can only contain cards that match your commander’s color identity, and except for basic lands, you can only include one copy of each card.

A well-built Commander deck needs a balanced foundation: around 37 lands for consistent mana, 10+ ramp spells to accelerate, 10+ card draw effects to maintain resources, and sufficient removal and board wipes to interact with opponents. The remaining slots go to your strategy’s key cards and synergistic filler.

Your mana curve matters. Include cards at every mana cost, with a focus on 2-4 mana spells. Too many expensive cards leads to slow starts. Too many cheap cards means you run out of gas. Balance is key.

Commander is a social format. The social contract matters as much as the cards. Build decks that create fun games for everyone at the table, and use brackets to ensure everyone’s expectations are aligned.
