Pokémon Masters EX has launched the Daily Battle Roll Cake Challenge, running until June 27, giving players a limited-time way to earn valuable upgrade materials. In this event, Sync Pairs can take on daily battles to collect Roll Cakes, which are used to raise move levels and unlock stronger performance in tougher content. The challenge refreshes each day, encouraging consistent play and team optimization throughout the event period. For players looking to power up their roster, this is one of the more efficient farming opportunities currently available in Pokémon Masters EX, especially for long-term progression and late-game builds.
