When a player enters the Challenge Hall when the Challenge Cup is occurring, they are brought on stage and seated at a table. There, players are challenged by three consecutive opponents, which are Club Members chosen at random from the eight Clubs in the game. The first and second times the player participates in the Challenge Cup, the third opponent is always Ronald.
The Challenge Cup will automatically start at certain points in the player's adventure, with a specific prize guaranteed at that time. If a player obtains another Master Medal without participating in the Challenge Cup, the Cup will end and the promotional card will be missed (although it is still possible to obtain later after all the pre-set Challenge Cups have come and gone).
After all of the pre-set Challenge Cups have come and gone, and once the player has defeated the Grand Masters, the Challenge Cup can occur at any time. Every time the player loads their save file, there is a chance that the Challenge Cup will be happening, although the exact chance of this happening is not currently known. If the player wins the Challenge Cup, they will receive a random Promotional Card (excluding the Legendary Cards and the Phantom Cards).
