CookieRun: Braverse is heading back to the Arena.
Devsisters has released Festival Arena, the newest booster set for CookieRun: Braverse TCG, bringing the Arena mechanic back into focus after an Arena-based deck won the 2026 Braverse TCG World Championship.
This isn’t just a handful of cards supporting an older strategy, either. Every card in Festival Arena features the [Arena] keyword, making this the first opportunity since Arena of Glory for players to build new Arena decks or expand the ones they already have.
AdvertisementThe set contains 160 regular cards and 49 Hidden Cards, and Festival Arena goes all-in on another part of its identity as well: turning its Cookies into superstar idols.
Devsisters sent me a Festival Arena booster display ahead of release, so alongside the official artwork, I’ve also included some photos from my own box throughout the article.
Arena Is Back After Winning the World Championship
Festival Arena arrives at an interesting time for the Arena mechanic.
An Arena-focused deck won the 2026 Braverse TCG World Championship, and now an entire booster set is arriving with additional cards built around that keyword.
AdvertisementFestival Arena also doesn’t replace what came before it. The new cards are designed to work alongside Arena cards from Arena of Glory, giving players the opportunity to revisit existing Arena strategies with considerably more options.
At the same time, having the Arena keyword doesn’t lock these cards into an Arena-only deck. Cards from Festival Arena can also be incorporated into decks that aren’t completely built around the mechanic. Which is most of mine, for now. I will be changing some to this soon.
Six Colors, Six Different Approaches to Arena
Red is all about activation and additional attacks. Festival Arena introduces effects that can activate your own Cookies and additional abilities that trigger when Cookies become active. Shining Glitter Cookie, Candy Apple Cookie, and Strawberry Mochi Cookie are among the featured Red Cookies.
AdvertisementYellow takes advantage of something players normally aren’t particularly excited to see: Cookies piling up in the Break Area. Its Festival Arena strategy intentionally builds up Arena Cookies there, with additional effects becoming available as their numbers increase. Madeleine Cookie, Financier Cookie, and Kouign-Amann Cookie represent Yellow.
Green turns its attention toward the Support Area. Arena cards can activate effects when they enter Support, while other cards interact with Arena cards already sitting there. Herb Cookie, Apple Faerie Cookie, and Mint Choco Cookie are featured.
AdvertisementBlue gets one of the stranger strategies of the set, manipulating the bottom of its own deck. Cookies can be placed there before other effects bring them back to the hand, with additional benefits available when the card on the bottom is a Level 2 Arena Cookie. Cream Soda Cookie, Popping Candy Cookie, and DJ Miya lead Blue’s Festival Arena lineup.
Purple introduces new Blocker cards. These can be used to protect Cookies during battle, while putting enough Arena Cookies with Blocker into the Break Area can enable additional effects and help bring Extra Cookies into play. Rockstar Cookie and Black Lemonade Cookie are the featured Purple Cookies.
AdvertisementFinally, Black expands its options around Special Play, introducing new conditions for triggering it and additional ways of bringing Extra Cookies into play. Red Velvet Cookie, Licorice Cookie, and Agar Agar Cookie are among the featured Black Cookies.
Putting all six together makes Festival Arena more interesting than simply bringing back a successful archetype. Arena acts as the common thread across the set, but what you’re actually doing with it depends heavily on the color you’re playing.
Festival Arena Takes Its Idol Theme Seriously
Then there’s the other half of Festival Arena.

And Devsisters did not exactly approach that concept with restraint.
Festival Arena reimagines its featured Cookies as performers, with different musical aesthetics, visual concepts and signature designs running through the set. The official artwork ranges from the bright pop styling surrounding the Red Cookies to Rockstar Cookie and Black Lemonade Cookie’s much heavier Purple presentation.
It gives each group an identity beyond simply changing the color around the border.

Braverse Continues to Grow
Festival Arena also arrives during a pretty significant year for CookieRun: Braverse.
AdvertisementDevsisters says more than 90 million cards have now been distributed globally, a substantial increase from the 50 million milestone the company reported at the end of 2025. Devsisters also launched the game on TCGplayer this year, while one of its Starter Decks was selected for Amazon’s 2026 Top 100+ Toys List. Devsisters
For a game that only launched in North America in July 2025, Braverse has been moving quickly. Devsisters
Festival Arena feels like another step in that growth rather than an isolated booster release. It’s revisiting an established mechanic, supporting a strategy that has already succeeded at the game’s highest competitive level, and giving all six colors new ways to interact with it.
And it manages to do all of that while dressing a bunch of Cookies like pop stars.

Festival Arena Is Available Now
CookieRun: Braverse Festival Arena releases October 2, 2026, through participating hobby retailers and game stores.
Individual booster packs contain nine cards with an MSRP of $3.99, while a booster display contains 28 packs with an MSRP of $111.72.
For players who already have cards from Arena of Glory, Festival Arena provides an obvious reason to dig those decks back out. For everyone else, having every card in the set tied to Arena makes this a pretty interesting starting point into the strategy.
AdvertisementI’m excited to see what players actually build from it. Arena just won a World Championship. Now everybody gets another set’s worth of pieces to start messing with it.
Festival Arena builds on one of CookieRun: Braverse’s strongest strategies without making every color play the same way. Its excellent idol-inspired artwork and collectible card treatments make opening packs nearly as enjoyable as exploring the new Arena combinations.
Pros
- Arena support extends across all six colors rather than focusing on a single deck
- Works with existing Arena of Glory cards
- Strong and cohesive idol/music theme
- Excellent artwork and card treatments
- Hidden Cards and signatures add collector appeal
Cons
- Arena was already a World Championship-winning strategy, so the amount of new support raises legitimate balance questions
- Players uninterested in Arena may get less out of a set where every card carries the keyword (the art is still worth it though)
- 49 Hidden Cards creates a sizable chase for collectors trying to complete the set
