From Bulbapedia, the community-driven Pokémon encyclopedia.
Kristin (Japanese: ハルナ Haruna) is one of the three Club Members from the Grass Club, under Club Master Nikki, in Pokémon Trading Card Game.
The player is required to battle with Kristin, in a 4 prize card match, in order to challenge Club Master Nikki. Upon defeat, Kristin awards the player with two Evolution booster packs.
Glittering Scales Deck
Glittering Scales Deck (Japanese: かがやくりんぷんデッキ) is the only deck played by Kristen in a 4 prize card match. Defeating Kristin gets the player a Legendary Power booster pack.
Kristin initially will not battle the player. If the player speaks to her in the communications room while GR-2 is in control of the Grass Club, she will give the player a free Legendary Power booster pack. After GR-3 leaves the Water Club, Kristin will have this deck ready for battle. If GR-3 leaves the Water Club before the Grass Club is freed, Kristin will be ready to battle immediately following the Grass Club being freed.
