Commander Bracket Checker
Find your EDH bracket and the cards pushing it higher. Free, no signup required.
Paste a decklist or a Moxfield, Archidekt or MTGGoldfish link to see which Commander bracket your deck most likely fits. Spellweave counts Game Changers from the official list, checks every two-card infinite combo in the deck, and shows the exact cards and combos behind the result.
Commander brackets help pods talk about deck strength using a shared rules framework instead of vague power-level numbers. This checker focuses on the card-based criteria players most often want to verify quickly before a game.
Wizards also lists mass land denial and chained extra turns as bracket factors. The checker doesn't count those yet, so a deck built around them may belong in a bracket higher than the result shows. Brackets are a starting point for a pregame conversation, and your table always has the final say.
How It Works
Paste your decklist or deck URL
Paste a public Moxfield, Archidekt or MTGGoldfish link, or paste or drop a decklist exported from Moxfield, Archidekt, ManaBox, MTG Arena or any tool with one card per line.
We scan every card
The checker counts Game Changers from the official list, finds two-card infinite combos using a published combo database, and flags banned cards.

Frequently Asked Questions
What are Commander brackets?
Commander brackets are Wizards of the Coast's official framework for describing a deck's power before a game. There are five: Bracket 1 (Exhibition), 2 (Core), 3 (Upgraded), 4 (Optimized) and 5 (cEDH). They give a pod a shared language, and they guide a pregame conversation rather than acting as hard rules.
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 don't allow two-card infinite combos. Bracket 3 allows only the ones that don't tend to end games early: Wizards frames Bracket 3 as games where you can expect to play about six turns before anyone wins. Brackets 4 and 5 have no combo limits. To judge which combos fit Bracket 3, the checker uses a published combo database's bracket classification for each combo and counts any two-card combo that wins on the spot as Bracket 4.
Why does my bracket differ from Moxfield or other sites?
Game Changer counts should match across tools, since the list is official. Differences almost always come from combos. Whether a combo ends games too early for Bracket 3 depends on how a deck plays, which no decklist can settle, so every tool makes a judgment call. Spellweave uses a published combo database's classification and counts any two-card combo that wins on the spot as Bracket 4. The result lists every combo that affected your bracket, so you can see exactly where a difference comes from.
What deck formats does this tool accept?
Deck links from Moxfield, Archidekt and MTGGoldfish, plus decklists exported from tools like Moxfield, Archidekt, ManaBox and MTG Arena, including Arena exports in other languages. Paste the text or drop the file. Section headers (Commander, Deck, Sideboard), quantities (1 Sol Ring) and commander markers (*CMDR*) are recognized.
How accurate is the Spellweave bracket checker?
The Game Changer count is exact, because it comes straight from the official list. The combo part is an informed estimate: the checker finds two-card infinite combos in a published combo database, but whether a combo ends games early also depends on how your deck plays. Mass land denial and chained extra turns aren't counted yet. Use the result as a strong starting point for the conversation with your pod.
Can I use this for cEDH?
Partly. Bracket 5 is cEDH, and Wizards defines it by competitive intent and metagame rather than by a card list, so the checker's highest result is Bracket 4. A cEDH list will show as Bracket 4 here, along with the Game Changers and combos that put it there, which is still useful when comparing variants or trimming for a specific meta.
What counts as a Game Changer?
Game Changers are cards on the official list published for the Commander bracket system. Because that list can change, the checker uses the current official version rather than a fixed static list on this page.
Bracket vs power level: what's the difference?
Power level is the older 1 to 10 community scale for overall deck strength, speed and consistency. Brackets are Wizards of the Coast's official five-step framework. They combine objective limits on specific cards, like Game Changers, with descriptions of how games should feel, like how early a deck should be able to win. The two scales correlate but don't map one to one.
Do I need to sign up to use the bracket checker?
No. You can use the checker without an account, up to a daily free-check limit. A free Spellweave account removes that limit and unlocks the deck builder, optimizer, and bracket-aware tuning if you want to fix a deck after checking it.
