I would, as follows, in an Episode Thought:
The Battle that Settles it All!
The episode would start out with Ash and Iris sleeping and Cilan is cooking (figures) for the trio. I would be battling my sister in a 3-on-3 battle, and we currently had my Leavanny and her Serperior out in battle. My sister would call out a SolarBeam which my Leavanny dodges due to the extreme heat, activating Chlorophyll. Serperior would try SolarBeam as I call out an Energy Ball, which causes an explosion, knocking out Serperior while Leavanny is terribly hurt. Cilan then walks over and sees the battle and wonders if Ash could take me on in a 6-on-6 battle, and wakes him up. I explain the explosion had caused my sister's Serperior out and my Leavanny needed to heal up. Ash uses a Lemonade on Leavanny perking her back up. We then engage in a battle. He sends out Pignite which, in response, I counter the Pignite with Dewott. Cilan comments that Ash would have a lot of work to do if he were to beat me. Then we start the battle, and I start by having Dewott use Razor Shell, which badly damages Pignite. I tell Dewott to use Water Pulse, which knocks Pignite out of the battle. Cilan says that in a traditional battle, the challenger (me in this case) can choose to switch Pokemon during the battle, which makes me recall Dewott. He sends out Snivy so I send out Leavanny again. I tell Leavanny to use X-Scissor, which puts Snivy on the brink of fainting, but instead, Snivy evolves into Servine, and Servine learns SolarBeam, and Leavanny (uncommandedly) uses Energy Ball as Servine uses SolarBeam, and Servine faints, Leavanny surviving the explosion. I recall Leavanny as Ash sends out Oshawott. I decide to send out Lilligant and have her use Magical Leaf. It is super effective, and causes Oshawott to faint. I recall Lilligant as Ash sends out Unfezant. I decide on sending out my secret weapon, a fully-evolved Scolipede, and have her start out by using Poison Tail. Ash counters with Air Cutter then Aerial Ace, knocking out Scolipede. I then recall Scolipede and settle on sending out Zebstrika. I then have Zebstrika use Charge Beam, severely hurting Unfezant. I have Zebstrika use Spark, knocking out Unfezant. The battle was officially 2-on-5, Ash at a disadvantage. He then sends out Pikachu, much to my dismay. I recall Zebstrika, and let Lilligant take over. Pikachu starts with Iron Tail, which I have Lilligant dodge. I then order Lilligant to use SolarBeam, but Ash knows either side can switch out Pokemon in case of a disadvantage, and he sends out Leavanny. I try to recall Lilligant, which works, and send out my own. The two Leavanny battle, and I have her use X-Scissor. Ash has his Leavanny use String Shot, which fails, as Leavanny runs at an amazing speed towards his Leavanny and uses the commanded X-Scissor. I then realize his Leavanny was near fainting, which it does. Ash makes a surrender, and I tell him it's all a part of the training. But then Cilan challenges me to a battle. I accept, and my second match goes under way. He sends out Crustle, and I keep Leavanny at the battle. With Leaf Blade and X-Scissor, Crustle faints. He sends out his Stunfisk. It faints with the same two moves. I eventually mop with Ash, Cilan, and Iris, and let Trip do the laughing.
