Since I had nothing better to do, I decided to push on and see how far I could take my winning streak in the Battle Maison after taking out Nita. Oddly enough, near-misses were much less frequent after Nita than before, and I saw a lot less legendaries than in the six or so battles right before her as well.
The first occurence of things going wrong, at battle 69 (hur hur its funneh cuz its a secks thang), would also be the last, with a Protect-loving Tauros in the lead. Of course, this meant I couldn't land Entrainment, so I had to send Heracross to clean up. Durant was quite damaged, and as a result I was hoping for a Pokémon that was bad with special attacks.
What I got was a Latios.
My only chance at this point was to click Pin Missile, hoping that Heracross could tank the incoming Psychic with its improved defenses and perfect IVs. Of course, that didn't happen, so in desperation I sent out Durant to X-Scissor it. It did about 75%, which wasn't enough, and Durant got obliterated, which meant the end of my streak, since Blaziken didn't have anything to deal damage.
So that's how it ended, sadly. I was hoping the final fight would be a little more epic at least, not like... this.
