Members of the Mezastar Club could access new features with the launch of this set, including the ability to customize their avatar with Dress-up Items (Japanese: きせかえアイテム), use Battle Tickets (Japanese: バトルチケット) to challenge Trainer and Battle opponents again at will, and redeem Present Tickets (Japanese: プレゼントチケット) to unlock special in-game items or limited Dress-up Items. Five new Trainers could be challenged during gameplay and defeating them all would unlock their Battle Tickets on the Mezastar Club. The tickets would also become available to members a certain period of time after the set's launch, regardless if they had yet to defeat all five opponents. Mezastar Club members could also receive a Flygon digital Support Pokémon Ticket for the duration of this set.
Battle Tickets displayed the name of a Trainer, the player's highest score against them, the overall rank of that score, and a QR Code for use with the console Multi-Scanner. The tickets also tracked any Dress-up Items a player could earn from them. One item, typically clothing matching the opponent's attire, could be unlocked for defeating them once, while challenge items could be unlocked by completing a set of three challenges during battles. These items could be differently-colored versions of the regular clothing, or new items entirely. Players could update the appearance of their avatar through the Mezastar Club, which would subsequently update on any machines after scanning their Memory tag. A limited Battle Ticket that allowed players to challenge Mezastar Navigator Sakura could be accessed through the Mezastar Club between May 7 and September 15, 2021. A Present Ticket that unlocked school-themed Dress-up Items could be redeemed through the club for the duration of the set.
Much like the fourth Pokémon Ga-Olé set, the Trade Chance! (Japanese: こうかんチャンス！) feature was added with the launch of this set, which had a chance to trigger during the Get Time! or Last!! Get Time! phases. An icon would appear on the "throw a ball" option if the player could activate Trade Chance! If selected, an Experienced Trainer (Japanese: せんぱいトレーナー Senpai Trainer), a more senior version of the player's avatar, would appear after a Pokémon had been caught and present the player with a random Pokémon to trade. The player could select either the offered Pokémon or the one captured originally using the "L" and "R" buttons.
Three new Partner Pokémon were available to players with Memory tags from this set: Gastly, Beldum, and Impidimp. More Support Pokémon could also be added to the player's starting roster with the release of physical Support Pokémon Tickets in Shogakukan publications.
