MTG Avatar The Last Air Bender Commander Box League

Buy a box, gameplay starts Friday 21st November 6pm to 23rd January 2026

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 matches.

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 box.
• 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.
