There is no reason to use kommo-O as it gets outclassed by like...everything in series 9. lel. If you really want to use it, then don't use that set lol.
Kommo-O @ Leftovers
Ability: Overcoat
EVs: 212 HP / 4 Atk / 132 Def / 12 SpD / 148 Spe
Careful Nature
- Iron Defense
- Body Press
- Protect
- Clangorous Soul
Please, don't use this. If you really are hellbent on using kommo-O, then I suppose a good partner would be eleki, as it is quite slow. Speed control is appreciated.
