The way I see it, Honchkrow = Staraptor whereas Froslass pushed SL Pikachu like how Metagross pushed KL Pikachu so that's why I paired the 2 of them up in this hypothetical match. I think Metagross pushed KL Pikachu more and I'd put KL Pikachu slightly over SL Pikachu, so that's why I'd say Metagross would take that battle, but the win would be hard fought. Drapion won't be able to do the kind of damage to Alain's team that it could do to Ash's team because Alain has 2 flying types that won't immediately be poisoned and better yet 2 steel types that are outright immune to poison. Drapion can likely do to Unfezzant what it did to Staraptor, but it's definitely not overpowering Charizard like that and Charizard can also Blast Burn the field in a manner analogous to underground Flare Blitz in order to eliminate toxic spikes. Bisharp is basically the perfect counter to Drapion since all of its moves would be effective on Drapion, but Drapion can only spam Pin Missle. Alain's Weavile is shown to be very agile and evasive meaning that by the Time Magmotar KOs it, it will likely have accumulated significant fatigue. Paul would not switch out Magmotar since it would have the type advantage over Bisharp. Bisharp would immediately thunder wave Magmotar further hindering its mobility. Bisharp would then proceed to use Guillotine and Magmotar would use Flamethrower, but Gulloitine would slash right through it and Magmotar then goes down. Paul finally beats Bisharp by baiting it to use TW on Ursaring which triggers Guts and then Ursaring proceeds to overpower Bisharp. Torterra has incredible endurance, but it would still fall to Blast Burn. I would compare Paul's Pokémon to Ash's like so
-Tier 1
Torterra, Electivire, Drapion, Guts Ursaring
-Tier 2
Ursaring, Magmotar, Froslass, Nidoking, Ninjask, Gliscor
-Tier 3
Aggron, Gastrodon, Honchkrow, Weavile, Haryiama
If we exclude AG, Paul vs Ash would be a close match with their best teams, but Ash would take the match mid diff if he has AG.
