>>55392021In Pokemon, positioning is a thing, which is more noticable in doubles as it has physical positions. It basically means what Pokemon you currently have out and in the back of your team vs what your opponent has.
A good position would be a Dragon Dance sweeper where your opponent has their resistances weakened, their faster Pokemon crippled, and your opponent currently has a Pokemon that can barely hurt you.
In the case of Cloyster, so long as your opponent doesn’t have shit faster than like Scarf Gengar, you can just cheese past your opponent’s healthy Toxapex with King’s Rock. You could have weakened the Toxapex more, but instead you just gambling on it flinching about half the time.
