Ash will use 2 Pokémon + Pikachu in the first round of 3 Pokémon, where Shota beats Ash's second Pokémon with Clawitzer, Pikachu beats Clawitzer and Pikachu and Aegislash fights until one of them is defeated and the field is changed from Forest to Rock/Fire. There, Ash-Greninja will fight Mega Sceptile.
There are 2 greyed out Pokéballs on Ash's portrait, meaning he's lost 2 Pokémon by the time Pikachu and Clawitzer fights.
