So, in the post-game of ORAS you can access the Battle Resort. I've beaten Nita and Everlyn two of the battle chatelaines. Is there any special reward from beating them or getting a high winstreak?
A victory against a Battle Chatelaine on the 50th consecutive battle on any of the Super challenges will reward the player with a commemorative monument in the lobby of the Battle Maison. There are 5 monuments to be won in total, corresponding to each of the Super challenges, with the color matching that worn by the appropriate Battle Chatelaine (purple in the case of Super Multi Battle).
After defeating the Chatelaine, the participants are awarded with a Skillful Battler Ribbon or an Expert Battler Ribbon.
You also get BP (Battlepoints). The number of BP you get is proportionate to how high your winstreak is so getting a high winstreak eludes to getting more BP :)
Lemme know if I missed anything and I hope I helped!
