[PlatinumDude]

Kyurem-Black @ Life Orb
Ability: Teravolt
EVs: 252 Atk / 4 SpA / 252 Spe
Naive Nature
- Freeze Shock
- Fusion Bolt
- Ice Beam
- Earth Power

Man, how come my Tapu Fini is never this tenacious? Took forever to find something to come anywhere near to OHKO.

Not a counter because it can't switch in on Moonblast.

Countering Fini instead:

Time to be a bit more creative with Gogoat:

-Bulk Up
-Horn Leech
-Earthquake
-Milk Drink
Nature: Careful
EVs: 252 HP/4 Def/252 SDef
Item: Leftovers
Ability: Sap Sipper

Gogoat can shrug off Fini's attacks while setting up with Bulk Up, then heal off the damage with a boosted Horn Leech.

Ah, but it would be a counter to Gogoat, but it would be boring to just repeat the post so,

Butterfree @ Buginium Z
Ability: Tinted Lens
EVs: 4 Def / 252 SpA / 252 Spe
Timid Nature
- Quiver Dance
- Bug Buzz
- Energy Ball
- Sleep Powder

Might take a few Quiver Dances, but Horn Leech is a 7HKO so...

Graveler-Alola @ Choice Band
Ability: Galvanize
EVs: 252 HP / 252 Atk / 4 SpD
Adamant Nature

Graveler is at best 3HKOd by bug bite and OHKOs back with Return. (switching in on +2 Scyther, crit has a small chance to kill).
