MTG Arena launches Competitive Brawl with unique ban list, no mulligan
Commander instincts still apply, but the free mulligan is gone. Competitive Brawl also arrives with rank-based matchmaking and a ban list built for the ladder.
If you carry paper Commander habits into Competitive Brawl, the free mulligan is the first one that will punish you. MTG Arena’s new ladder format launches on June 23 with rank-based matchmaking, a separate ban list, and none of the safety net that Brawl players are used to in casual play.
The shell still looks familiar to Commander regulars. Competitive Brawl uses 100-card singleton decks, one commander, 25 starting life, and color-identity rules, with a legendary creature, planeswalker, Vehicle, or Spacecraft leading the list. That is where the comfort ends. Unlike normal Brawl, Competitive Brawl gives no free mulligan, so the loose keeps that work fine at a kitchen-table pod become a much bigger gamble on Arena.
Wizards of the Coast is also treating the format as its own lane rather than a ranked clone of the casual queue. The matchmaking uses a player’s Constructed rank and rating, and the company says Competitive Brawl follows different goals and a different banned-list philosophy. That distinction matters immediately because the new list is loaded with cards Commander players know well as problems: Ajani, Nacatl Pariah; Nadu, Winged Wisdom; Lutri, the Spellchaser; Oko, Thief of Crowns; Ragavan; and Wrenn and Six are all out.
The ban philosophy grew out of earlier Brawl testing in late 2025 and early 2026, when Wizards described Ajani, Nacatl Pariah as a dominant commander that narrowed deck diversity. Wizards has said it will issue wildcard refunds for any future bans in Competitive Brawl, another sign that the format is being managed like a serious competitive queue rather than a casual side project.
The name changed on June 8 after player feedback that Ranked Brawl sounded like the ranked and unranked queues would share the same ban list. Before launch, Wizards used a June 2-15 Modified Ranked Brawl, later framed as a competitive Brawl Metagame Challenge, to preview the rules under the same special bans. The June 23 debut also lands with Magic: The Gathering | Marvel Super Heroes, and Wizards says Brawl is now the second most played Constructed format on MTG Arena. For Commander players, the message is blunt: the deckbuilding rules feel familiar, but the first hand and the banned list will demand a very different instinct from the very first match.
