The player can't duel Murray until the player has four Master Medals. Players who are able to beat Murray will receive the Psychic Medal and two booster packs.
The Psychic Club is the only club whose main hall cannot be entered at the beginning of the game. It's being blocked by Stephanie, who urges the player to go to the Lightning Club.
Once the player scares GR-4 away from the Lightning Club to here, the player may enter the top room and battle Stephanie and Club Master Murray. Defeating Murray frees him from the mind control, at which point GR-4 demands a battle. Once GR-4 is defeated, he leaves the club and both Murray and Stephanie remain to battle on request. The other club members, though present, are still missing their cards at this point and cannot battle.
