What the title says. Was the AI or the Pokémon teams improved in ORAS? Is it an exact copy of XY's Battle Maison?
The Battle Maisons in X/Y and ORAS are pretty much the same. The only differences are the items that you can buy with BP and possibly the design, but I'm too lazy to check if the design is any different. (You can see the item differences here.)
Hope this helps!
