So lots of people are suggesting doubles. I don't intend on aiming for an amazingly-long winning streak; I just want to get the BP that I need for the good items, along with the Starf and Lansat Berries. Is doubles the best way to do this in the most timely manner?
Also, I thought that the Level 1 Aron was a singles gimmick, and I've only seen it hold Shell Bell and with Sandstorm support. In theory, it sounds so poor in doubles because it can just be double-targeted circumvent Sturdy. How exactly does this doubles Berry Juice version work?
Eppie has a write up of how his doubles team setup as well as some battle videos demoing how he uses his team over here:

The idea behind a level 1 Aron is to exploit the AI of the Battle Maison. In the BM, AI pokemon have a tendency to go for the OHKO above all else and since Aron has low HP, it becomes AI's favorite target. Aron has sturdy however preventing it from being OHKO. Furthermore with berry juice Aron will fully restore its HP after taking its first hit. This allows Aron to take 3 hits before it's KOed. Its starting partner, Dusclops with Eviolite has great bulk and can take a ton of hits before it's KOed, allowing it to set up trick room which allows Aron go first each turn. Furthermore, Dusclops has night shade so when Aron uses endeavor on an opposing pokemon, it'll reduce it to 12 HP which will allow Night Shade to easily finish off that pokemon. So a run-of-the-mill match with Aron will go something like:
Turn 1: Aron uses Protect, Dusclops uses Trick Room
Turn 2: Aron uses Endeavor, Dusclops uses Night Shade. 1 opposing pokemon is KO-ed.
Aron is hit by the remaining pokemon, Sturdy activates, berry juice restores Aron to full HP.
Turn 3: Aron uses Endeavor, Dusclops uses Night Shade. 1 opposing pokemon is KO-ed.
Aron is hit by the remaining pokemon, Sturdy activates, Aron has 1 HP.
Turn 4: Aron uses Endeavor, Dusclops uses Night Shade. 1 opposing pokemon is KO-ed
Aron is hit by the remaining pokemon and Aron is KO-ed.
Now at this point having KO-ed 3 opposing pokemon Conkeldurr and M-Kang should easily finish off the match.
With this there are things to watch out for like priority users that will KO Aron before he manages to land endeavor (however even in cases like these I've managed to KO at least 2 of their pokemon before Aron is KO-ed). However the big pain in the ass is status moves like burn, poison, and frozen (100% of my runs ended because of a Glaceon freezing me). Then there is the Hail weather condition that will break Aron's sturdy which is really annoying as well so you might want to switch out to Conkeldurr during such times.
EDIT: Forgot to add that Walrein and its Sheer Cold is another big pain in the ass when it KOs OHKOs Dusclops before it manages to setup trick room (it happens in one of Eppie's videos).
