Ugghhh, I feel so stupid, my streak at the Battle Maison just ended at 54, but not because of hax, because I stopped paying attention. Damn I was confident that I could get a good streak going, and start farming BP.
It was my Rotom-H / (Mega) Gyarados / Aegislash against a Ludicolo / Quagsire / Samurott.
The problems started with Ludicolo, who I should have used to set up Aegislash on, but instead I figured screw it, I'll use Gyarados for once. I set up a couple of Dragon Dance's, but it Leech Seeded me, and they killed each other, rather than have a +6 Aegislash and a Ludicolo corpse. Anyway, out comes Quagsire against Aegislash, I get to +4, and finish it off because it kept using Earthquake and I didn't want to keep stalling with King's Shield. I then use Shadow Sneak to finish it off, and do the same thing to Samurott, which puts it at 70%, but then it KOs Aegislash. I send out Rotom-H to finish the job, but that thing was Scarfed, and OHKO'd with Hydro Pump. I'm surprised it managed to one shot it, Rotom has tanked a lot of Surfs along the way.
I feel so stupid for not paying attention, which is Rule #1 in the Tower / Subway / Maison. And ironically I lost while looking at the Pokemon X/Y Soundtrack on iTunes, while playing a game which has the entire soundtrack on it already.
tl;dr - streak ended because i'm an idiot.
