By talking to the attendant next to the arena, the player may start a battle challenge to earn Battle Points (BP) and increase their current win streak, which will be displayed on their Vs. Recorder along with their all-time record win streak. Battles held in the Battle Maison differ from regular battles in a number of ways. When challenging the Battle Maison:
All Pokémon above level 50 will be set to level 50. Those under level 50 will remain at their current level.
Pokémon are fully restored after each battle, including any held items lost or gained during battle.
The player may put the challenge on hold at any time without any penalties to their current winning streak.
Number of eligible Pokémon
2 per player

50 (Battle Chatelaine)
51 and more

Battle Chatelaines are sometimes fought instead of regular Trainers. Unlike regular Trainers who use a set of Pokémon randomly drawn from their roster, Battle Chatelaines have a predetermined team for every battle, although the team order does vary. The Battle Chatelaines also appear in Tag Battles, where they form teams. In Tag Battles, the Battle Chatelaines use two Pokémon from their Single Battle parties.
