Pokémon Trading Card Game/Science Club

The Science Club uses Pokémon cards of the Grass type that are Poison types in the mainline games. The club master Rick is in the middle of an experiment and does not want to be disturbed so you cannot face him right away.

Club Master: Rick
You'll have to defeat Joseph who stands guard just beyond the doorway of Rick's room in the club. He'll move aside once you've won, letting you enter and challenge Rick.

A victory over Rick results in you obtaining the Science Medal.

Ishihara's Rare Cards
There is a boy in the lounge of the Science Club who will tell you about Ishihara, a card collector. Once you have talked to this boy Ishihara will appear in the house in the northwest of the world map. He'll want to be traded some rare cards and will give you some rare Pikachu promotional cards in return.
