Commander Bracket Checker

Paste your decklist and get its bracket the way the rules actually define it — by counting. Every Game Changer, every extra-turn card, every land wipe and every two-card infinite combo gets named, so when your pod asks “what bracket is that?” you can hand them the receipts instead of a guess.

How the brackets are decided

Wizards' bracket system (in beta since February 2025, last updated February 2026) draws its lines with four countable things. Tutors were dropped as a criterion in October 2025 — we still count them, but they don't move the bracket.

Bracket	Game Changers	Extra turns	Mass land denial	Two-card infinite combos	Games end
1 · Exhibition	None	None	None	None	Turn 9+
2 · Core	None	A few, not chained	None	None	Turn 8+
3 · Upgraded	Up to three	A few, not chained	None	None that go off early	Turn 6+
4 · Optimized	Any	Any	Allowed	Allowed	Turn 4+
5 · cEDH	Any	Any	Allowed	Allowed	Any turn

The Game Changers list currently holds 53 cards; we read it from Scryfall every week, so a change reaches this page within days. What no checker can see is intent: a deck with none of these flags that still wins on turn five is a Bracket 4 deck, and the honest thing is to say so at the table. What we give you is the floor.
