This is a record of Season M-3, where the team was revamped multiple times until 100 wins (Doctor title) were achieved, centered around Mega Mawile, a Pokémon I've been attached to since the XY era. Initially, I pushed with Trick Room (Farigiraf + Torkoal), but as weaknesses against Charizard Y and Garchomp continued to emerge, I finally settled on a form where Trick Room was safely set up with Vivillon's sleep, reinforced by Garchomp, Gallade, and Aerodactyl.[Key Pokémon Points]Mega Mawile: Confirmed for adoption after removing Sylveon from the team to handle Fairy types alone. The central firepower of the Trick Room combination.Farigiraf: Changed from Helping Hand to Protect (the author stated that the pros and cons were balanced, so it couldn't be definitively decided). Trick Room partner.Torkoal: Changed from initial Life Orb to Charcoal (because the item overlapped with Mega Mawile). The author later evaluated that Life Orb would have been better. Mentioned that Sunny Day was never used in actual battles.Vivillon (adopted when rating was highest at 2071): Role to put the opponent to sleep at the start to safely set up Trick Room or disrupt Eruption, with the side effect of breaking ground-type move consistency. Often makes opponents flinch with Rock Slide.Garchomp (adopted mid-season): Adopted to pressure Charizard and maintained thereafter.Gallade (finally readopted): For countering Rain and Duraludon. Sacred Sword was essential for dealing with Duraludon, so its adoption was confirmed.Aerodactyl (finally adopted): As a flying type that floats above the ground, it can use Rock Slide from above against Fire types, and secure a hit on Garchomp with Ice Fang. Evaluated that it also became advantageous against Sableye and Duraludon with Sunny Day.[Basic Lead and Operation](At rating 2071) The basic lead was Farigiraf + Vivillon, Mega Mawile + Torkoal. Against top-tier Pokémon (Charizard, Florges, Whimsicott, Garchomp, Kingambit, Basculegion), it was Vivillon + Hisuian Arcanine, Mega Mawile + Farigiraf. Against rain teams, it was Vivillon + Gallade, Farigiraf + Torkoal. Against regular Trick Room teams, it responded with a Vivillon-centric set of three. If Fake Out was seen on the opponent's team, Farigiraf was often removed from the lead and brought in later.[Opponents to Watch Out For]Mega Charizard Y was a weakness that was never resolved and could only be dealt with under Trick Room. There was almost no chance of winning against rain teams with simultaneous Pelipper + Politoed or Sableye's manual rain. Fire types in general, especially Incineroar, which increased in the environment, were a burden (based on the period when Hisuian Arcanine, weak to Intimidate, was adopted).
