It pains me to say this. But as much as Lunatone completely shreds Nidoking like a Toxapex catching an Earth Power, Lunatone sadly is not ranked. You'll have to choose a different pokemon
Lunatone @ Leftovers
Ability: Levitate
EVs: 252 HP / 4 SpA / 252 SpD
Calm Nature
IVs: 0 Atk
- Stealth Rock
- Earth Power / Psychic
- Moonlight / Pain Split
- Toxic
Lunatone acts as a defensive counter to Nidoking.
Being able to both resist and immune to both of nidoking's stabs allows it to safely come in and set rocks as well as threaten it with earth power.
