The metal energy from Neo genesis reduces both the damage done by the pokemon is attached to(if the pokemon is not metal) and the damage done to the pokemon is attached to. So, If you have 2 metal energys attached to the piloswine, then it does to itself 30 base damage minus 20 on account of protection, minus 20 more on account of pilloswine not being metal type.
