I had previously decided to challenge the Elite Four again for the fun of it and also for experience I suppose haha. I entered Koga's lair and the battle soon began. His first Pokemon. Skuntank was easy to defeat thanks to Groudon's Earthquake but then things got complicated as Koga was able to Poison some of my Pokemon with some of it's Poison-type moves. Defeated Swalot and Muk with Earthquake as well, then used my Luxray's Thunder on his Crobat. Won that battle, but I had to heal everyone's status condition with Full Heal. Went to the next room and challenged Bruno. Every Pokemon was easy to defeat with my Espeon's Psychic, except Lucario. It used Close Combat twice and actually caused Espeon to faint. Had to switch to Houdoom and it's Flamethrower to win. Saved after that, I'll challenge Karen tomorrow.
