Ash realized that only one of his Pokémon would be able to endure the attacks from Clay's Excadrill and keep enduring them until there was a chance to counterattack and that was Ash's Roggenrola. Ash's Roggenrola kept on enduring all the attacks for quite awhile until it evolved into Ash's Boldore. After evolving it learned two new moves and it became even stronger than when it was a Roggenrola. The battle then turned into a frontal power match between two Pokémon with strong bodies and Ash's Roggenrola was able to counterattack against Clay's Excadrill. Clay's Excadrill was unable to match the power of Ash's Roggenrola's Rock Smash and Clay's Excadrill was knocked out giving Ash the overall victory in the gym battle.

Tag Battle VS Bianca and Professor Juniper

After Bianca's Shelmet and Professor Juniper's Karrablast evolved via link trade, Professor Juniper suggested to Bianca that they team up and have a tag battle against Ash and Cilan. Ash's Boldore and Cilan's Crustle had recently evolved so they decided to use them against Bianca's Escavalier and Professor Juniper's Accelgor. The beginning of the battle went well for Bianca and Professor Juniper as Bianca's Escavalier's Fury Attack was excellent but Bianca hadn't commanded it to use it. Realizing that Bianca's Escavalier wasn't following commands, Ash and Cilan decided to focus their attacks on it. Professor Juniper's Accelgor managed to protect Bianca's Escavalier as Professor Juniper explained that tag battles were all about teamwork. Professor Juniper's Accelgor lost a lot of stamina defending Bianca's Escavalier after it used Substitute and Bianca's Escavalier finally realized that it needed to listen to Bianca otherwise it would loose the battle. After Professor Juniper's Accelgor did a quick Recover, Professor Juniper's Accelgor and Bianca's Escavalier started working together and they combined their Hyper Beam attacks which knocked out Ash's Boldore. Cilan's Crustle fought back with its powerful Rock Wrecker to knock out both Bianca's Escavalier and Professor Juniper's Accelgor and give Ash and Cilan the tag battle win.
