What Is Commander Box League?

Offered during the Prerelease period, Commander Box League is a Sealed event in which players open a Play Booster box, build a 60-card Commander deck, and play in Commander Box League games throughout the Prerelease period.

Players purchase a Play Booster box as part of entry. Games are played with normal Commander rules, but deck building follows modified rules for Commander Box League.

Commander Box League Deck Rules

After players open their Play Booster box, they construct a 60-card Commander deck from the contents. Buy-a-Box and Commander promos may not be used in deck building.

• Decks may include multiple copies of cards opened from the Play Booster.
• Any legal commander opened is allowed.
• Color identity rules in deck building are ignored; players may build decks with any colors they want, regardless of their commander's color identity. Note: commander color identity still applies when cards refer to color identity (for example, with Arcane Signet).

Players may adjust their decks between games using cards from their Play Booster box.

Pairing and Gameplay

Pods are composed of three to four players, with pairing left to the store to decide. The entry fee is at the store's discretion, and stores are responsible for providing the Play Booster box for entry.

Normal Commander rules apply for gameplay in these events (e.g., 40 starting life, commander damage tracking, etc.).
