Okay nvm, the cloyster I saw wasn't right nature.
Will you accept doing the 2 B.P.s for me? ^^
EDIT: Also, since your RNG breeding, you can choose to make it shiny if you want. I don't mind about shininess. Since you need to use the 'shiny egg' tab for nature and abilities, you can tick shiny if you want aswell since it causes no further delay.
EDIT2: Hariyama - Thick Fat is Ability 0
Cloyster - Shell armour is Ability 0
