From Bulbapedia, the community-driven Pokémon encyclopedia.
Miyuki (Japanese: ミユキ Miyuki) is a member of Team Great Rocket from Pokémon Card GB2: Here Comes Team GR!. She's one of the Trainers at the GR Grass Fort.
She refuses to duel against the player unless there are only Energy Cards in the active deck. Her deck, Sticky Poison Gas Deck (Japanese: どくのベトベトガスデッキ), focuses on Pokémon.
When defeated, she gives out one We Are Team Rocket booster pack. Also, when defeated for the first time, she opens the door to the next room, allowing the player to reach Morino, the Fort Leader of GR Grass Fort.
