Frequently Asked Questions
What are Commander brackets?
Commander brackets are the official power-level framework introduced by the Commander Format Panel and Wizards of the Coast. They provide a shared language for players to communicate deck power levels before a game starts, using a scale from Bracket 1 (casual) to Bracket 4 (optimized).
How do game changers affect my bracket?
Game changers are specific cards designated by WotC as particularly powerful. Brackets 1 and 2 do not allow any game changers. Bracket 3 allows up to 3. Bracket 4 has no restrictions. The number of game changers in your deck is one of the primary factors in determining its bracket.
What combo restrictions exist for each bracket?
Brackets 1 and 2 do not allow two-card infinite combos. Bracket 3 restricts early-game two-card infinite combos (where the combined mana value of the two pieces is 7 or less). Bracket 4 has no combo restrictions.
Why does my bracket differ from Moxfield or other sites?
Spellweave evaluates brackets strictly by the official Commander bracket rules: game changer card counts and two-card infinite combo restrictions. Other sites like Moxfield may also factor in mass land denial, extra turn cards, or subjective power assessments. These additional categories are not part of the official bracket framework.
What deck formats does this tool accept?
This tool accepts decklists exported from Moxfield, Archidekt, ManaBox, and plain text formats. You can paste text with section headers (Commander, Deck, Sideboard), numbered entries (1 Sol Ring), or annotated exports (*CMDR* markers).
