Sixtro #14 Sets Cosmo Ban for Brawl Stars
Sixtro Tournament #14 has an unusual rule combination on its October 11 Brawl Stars listing: Cosmo is banned, while Buffies are allowed. The community bracket uses a Power League-style pick-and-ban phase, with each team permitted to remove up to three brawlers. Those choices shape preparation before any match result exists.
The organizer’s Matcherino page lists the event for Sunday, October 11 at 1:00 PM GMT+1. Its status was still shown as registering when checked; the page establishes the published rules and schedule. Competitors should treat the live bracket as the source for any later outcomes. A listed start time is operational information that can move; check-in and match notices on the event page take priority.
The format grows longer as the field narrows. The published rules label top-128 through top-64 play as Bo1 of Bo3, the next stage through the semifinals as Bo3 of Bo3, and the final as Bo5 of Bo3. Those are the organizer’s format labels. The practical point is that a squad preparing for later rounds needs more than one narrow strategy; the bracket’s later stages allow more repeated decisions.
The map pool spans Gem Grab, Bounty, Brawl Ball, Knockout, Hot Zone and Heist. The organizer says maps will be chosen at random from its selected BSC 2026 pool. Preparation therefore has to cover several objectives and routes across the published pool. The event page also says using bugs can cost a set.

One exclusion changes the draft
Cosmo’s explicit ban is a tournament rule, not a claim that Supercell has removed the brawler from normal play. Conversely, the page says all Buffies are authorized for this bracket. Teams should interpret both rules together: they can prepare empowered picks, but not Cosmo. Because each team can ban up to three additional brawlers during the Power League draft, actual match options will narrow further once opponents make their selections.
That structure makes the map pool relevant. A draft for a Gem Grab map asks different questions from a draft for Heist or Knockout. Random map selection and up to three bans per side make flexibility valuable throughout the bracket. This is an interpretation of the published format; it does not predict any winner or imply a specific brawler will be picked.
The tournament also has practical participation rules. A team registers through Matcherino, and one member must join the event Discord for organizer information. Check-in begins one hour before the listed start and is mandatory. Player tags must match the tags connected to Matcherino so the in-game invitation can reach the correct accounts.
The listing describes automated results recording in the Matcherino bracket and asks teams to bring proof if a dispute occurs. A captain who arrives without the right account tag or misses check-in can face an avoidable administrative problem before draft strategy ever matters. The event’s check-in and Discord instructions deserve as much attention as the headline ban.
This is separate from the site’s Ready4 coverage. Ready4 ran Turkish team and solo events with their own prize terms. Sixtro #14 is a different organizer, a multi-mode Power League bracket, and a rule story centered on Cosmo’s exclusion and allowed Buffies. Combining the events into one result or treating their formats as interchangeable would mislead readers.
A short pre-match checklist
Read the live event page before joining. Confirm the current schedule, complete team registration, make sure the needed Discord member is present, and check in during the organizer’s window. Check that each player’s in-game tag matches the account used on Matcherino and leave unrelated lobbies when a match invitation is due.
For strategy, plan across all six named modes and expect map selection from the published pool. Remove Cosmo from practice drafts for this bracket, then consider how three bans on each side can change available answers. Buffies being allowed may affect a team’s choices, but the event page does not rank those choices.
The verified October 11 story is the published format and its distinctive restrictions. After play, a results article would need the organizer’s bracket and recorded scores. No result is inferred from a registration label or scheduled final.
- Cosmo is banned in Sixtro #14; Buffies are allowed.
- Each team can ban up to three additional brawlers in the Power League draft.
- Teams need Matcherino check-in, correct player tags and one Discord representative.

| Rule area | Organizer listing | Competitor takeaway |
|---|---|---|
| Brawler pool | Cosmo banned; Buffies allowed | Prepare legal alternatives |
| Draft | Up to three bans per team | Keep several options ready |
| Maps | Six modes, random maps from stated pool | Practice more than one objective |
Sixtro #14 stands out less for an announced favorite than for the decisions its rulebook forces. The Cosmo ban, permitted Buffies and up-to-three-ban draft create a narrower and more flexible strategic problem across six game modes. The organizer’s October 11 listing also makes registration, check-in and account tags part of the competitive preparation. At the time reviewed, there was no completed bracket result to report. Readers following the event should use the live Matcherino bracket for outcomes and keep this preview tied to the published rules.
