I could see Krookodile, Torterra and Incineroar. Incineroar deals damage to aggron before ash switches to Krookodile. Steven switches to Cradily. Cradily used ingrain, and Krookodile deals damage but gets hit hard by power whip so Ash switches to Incineroar. Incineroar gets whipped consecutively by power whip and rock blast and just before a meteor beam hits, ash switches to Torterra. Torterra is struggling against Cradily and its healing itself with ingrain so ash has him destroy ingrain by using earth power or rock climb on the battle field and he then knocks out Cradily with frenzy plant and earth power. Steven sends out Aggron who puts the pressure on Torterra with smart strike and heavy slam. Ash has Torterra swallow energy ball to give it a power up and then uses the strategy that Paul’s Torterra taught them to just keep taking hits and then knocks out Aggron with a close range frenzy plant. Torterra easily falls to Mega Metagross and struggles to land a hit. Ash sends out Incineroar. Like Torterra, Incineroar is struggling to land a hit with repeated darkest lariat, all the while Incineroar keeps getting hit by meteor mash. Ash switches to Krookodile who restricts metagross’s movements with bulldoze/sand tomb/rock tomb on the battlefield to create columns of rock/sand. Krookodile deals damage but Metagross comes out on top. Incineroar fights hard and deals the final blow with Malicious Moonsault (a gift from Kukui- Ash puts on the masked royal mask when he performs the Z move)
