Gligar @ Eviolite
Ability: Hyper Cutter
EVs: 252 HP / 4 Atk / 252 SpD
Careful Nature
-
Earth Power Earthquake
- Defog
- Roost
- U-turn
Basically the easy way to do this is switch in on a obvious STAB move. Scout for Ice Beam, if it has it go to said check or counter, if not, proceed to beat the living crap out of nidoking here. You always 2hko, none of his other moves even
4HKO you besides Ice Beam, which honestly isnt as common with the myriad of options people have found for king now, including Fire Blast (Gligar tanks it) and rocks (Gligar defogs it) U-turn for momentum, Stealth Rocks if you need them. Very simple. Also cockblocks Mega Ampharos extremely hard. Just avoid Knock Offs or you don't tank special hits well.
