I managed to defeat Oleana. My Centiskorch took down her Froslass, my Toxtricity handled her Milotic, my Inteleon sniped her Salazzle, my Corviknight defeated her Tsareena, and my Copperajah was almost taken down by her Garbodor, but prevailed in the end.
After defeating Oleana, I didn't have to deal with Chairman Rose straight away, but instead was allowed to go to the Wyndon Stadium again, where I was ready for the finals, but got interrupted by Bede. Against his Mawile, I sent out my Centiskorch. I had my Centiskorch use Coil once, then use Flame Wheel against his Mawile, leaving it with little health and forcing Bede to waste his Full Restore. After that, a crit Flame Wheel took out his Mawile. My Corviknight took care of his Gardevoir. The rest of his team got swept by my Polteageist, with one Nasty Plot boost and one Weak Armor boost.
Afterwards, time for the finals. The finals started off with me fighting Nessa again. She started off with a Golisopod, and I started with my Toxtricity. I let my Toxtricity use Discharge, in case Nessa's Golisopod would survive it. It did not. For her Baraskewda, I let my Eldegoss use Cotton Spore. Her Barraskewda took down my Eldegoss, but the job was done. My Toxtricity finished off her Barraskewda, as well as her Pelipper. While I could let my Toxtricity take down her Seaking and Drednaw, I gave that honor to my Flapple instead.
My next opponent was Bea. I let my Grimmsnarl take down her Hawlucha. Against her Falinks, I let my Corviknight use Hone Claws, expecting her Falinks to use Close Combat. Instead, her Falinks used Rock Tomb to slow down my Corviknight. Despite this setback, my Corviknight was able to mow down Bea's team.
After defeating Bea again, I had to fight Raihan again. He started off with a Torkoal with Drought. I ruined his strategy by letting my Inteleon use Rain Dance. While his Torkoal had to charge up his Solarbeam, my Inteleon took it down with a Snipe Shot. My Flapple took down his Goodra and his Turtonator after setting up a few Dragon Dances. For his Flygon, I didn't want to try my luck with Dragon Rush, so I let my Grimmsnarl take care of it, although it did manage to use Sandstorm first. Finally, he sent out his Duraludon, and I sent out my Grapploct. Even with the sandstorm, my Grapploct won with just 2 hits.
After defeating Raihan again, Leon was prepared to fight me. However, Chairman Rose put his evil plan in action. To stop him, I have to go to the Slumbering Weald again, to search for Zacian.
