Devsisters released Festival Arena, a new booster set for CookieRun: Braverse TCG that reimagines fan-favorite Cookies as superstar idols. Every card in the set features the Arena keyword, marking the mechanic’s return since Arena of Glory.
Festival Arena is the first dedicated Arena set released following growing competitive interest in the mechanic. According to Devsisters, an Arena deck won the 2026 Braverse TCG World Championship, driving player demand for new cards built around the strategy.
The set contains 160 regular cards and 49 Hidden Cards. Individual booster packs cost $3.99 MSRP and contain nine cards, while booster displays with 28 packs are priced at $111.72 MSRP. Collector cards include Hidden Cards with Cookie signature artwork and autograph-signed in-character cards.
The set provides new tools across all deck colors, from Purple’s Blocker cards to new Special Play conditions in Black. Arena cards in Festival Arena work alongside existing Arena cards or in decks that don’t use the keyword at all.
Festival Arena caps what the studio describes as a strong year for Braverse. A related Starter Deck made Amazon’s 2026 Top 100+ Toys List, and according to Devsisters, Starter Deck orders on Amazon have nearly doubled since July.
