Bewear has the Fluffy ability, which halves the damage of moves that make contact, but doubles the damage it takes from Fighting type moves. Your best bet is to use special moves, Fire moves, or moves that don’t make contact. Hariyama’s Knock Off will do some serious damage if it uses it against a Pokémon with a held item, so beware. Crabominable has the Fightinium Z, so it can use its Z-Move, All-Out Pummeling.
Both Golem and Probopass have the Sturdy ability, so you can’t defeat them in one hit. Lycanroc has the Rockium Z, so it can use its Z-Move, Continental Crush.
Try not to let Drifblim set up Amnesia, since it can use Baton Pass to pass the boosts to another Pokémon in her party. Sableye and Froslass have Confuse Ray, which can cause you problems if you’re unlucky with your Pokémon hitting themselves in confusion. Palossand has the Ghostium Z, so it can use its Z-Move, Never-Ending Nightmare.
Skarmory has the Sturdy ability, so you can’t defeat it in one hit. It also uses Spikes, so that your Pokémon take damage every time you switch them. Crobat and Oricorio can confuse your Pokémon, which can cause you problems if you’re unlucky with your Pokémon hitting themselves in confusion. Don’t use a move that makes contact while Toucannon’s using Beak Blast; otherwise, it will cause your Pokémon to be burned. Toucannon has the Flyinium Z, so it can use its Z-Move, Supersonic Skystrike.
Lycanroc is Rock-type, so use a Water, Grass, Ground, or Fighting-type attack. Beware of Stealth Rock, which hurts your Pokémon when you switch them in (doing low damage to Pokémon that resist Rock type attacks, normal damage against Pokémon that have no weakness or resistance to Rock type attacks, double damage to Pokémon with a single weakness to Rock type attacks, and quadruple damage to dual type Pokémon whose types are both weak to Rock type attacks). Alola form Ninetales is Ice/Fairy-type, so use a Steel, Fire, Poison, or Rock type attack. Steel is especially good, since Ninetales takes quadruple the normal damage from it. Braviary is Normal/Flying-type, so use an Ice, Rock, or Electric type attack. Note that it has Tailwind, which doubles the speed of his entire team for 3 turns. Magnezone is Electric/Steel-type, so use a Fire, Fighting, or Ground type attack. Ground is especially good, since Magnezone takes quadruple the normal damage from it. It has the Sturdy ability, so you can’t defeat it in one hit. Snorlax is Normal-type, so use a Fighting type attack. Incineroar is Fire/Dark-type, so use a Water, Ground, Fighting, or Rock type attack. It has the Firium Z, so it can use its Z-Move, Inferno Overdrive. Primarina is Water/Fairy-type, so use a Grass, Electric, or Poison type attack. It has the Waterium Z, so it can use its Z-Move, Hydro Vortex. Decidueye is Grass/Ghost-type, so use a Fire, Flying, Ice, Ghost, or Dark type move. It has the Grassium Z, so it can use its Z-Move, Bloom Doom.
