To make this set better (I will assume UU), change it's Ev's to 252 atk, 252 spe, 4 def, adamant nature. Clangorous soulblaze will be used to set up initially, then you sweep. You need to set up first so your defenses are enough and you speed hits 400+, allowing you to destroy most things in your way. don't send Kommo-o out against a fairy type, it will most likely need the boosts to defeat it. Never use clanging scales unless your fighting a physical wall that has low special defense and only if you need to.
