After having done some serious training on the S.S. Aqua ship, I decided to do even more training to level everyone on my team up to level 100 as is usually my in-game goal. I went to the Pokemon League and tried to challenge them but got interrupted by my rival since it was Wednesday. We fought and I beat him easily except his Meganium was a bit of a challenge in the end. After that I had to heal and buy recovery items since some of my Pokemon will probably receive battle damage against the Elite Four. I then entered Will's room and challenge him. Everything went well thanks to my Houndoom and it's Crunch but his Bronzong wouldn't faint even against a full-power Fire Blast. Had to switch and use Groudon's Eruption to seal the deal. Got money and was allowed to proceed to the next room. That was done and I saved before I challenged Koga since challenging him requires tactics.
