I was wondering if moves like Knock Off are useful against trainers in Pokémon unbound. How common do trainers/gym leaders have Pokémon with held items in Difficult Mode for Unbound. I got Alolan Muk and see many forums discussing how useful Knock Off is for him but it’s weaker than Crunch so I wanna know if I should replace it for the latter.
