I am. Its the bane of my existence

When your team consists of Skeledirge, Kilowattrel, Quaquaval, Grimmsnarl, and Haxorus, you need a reliable way to take a Ghost/Fairy Type down, and fast.

Wow. I don't know why I like them so much, but you could have a couple of staller Pokémons on your mostly offensive team.

like what?

I don't play much, but like any Pokémon that can reset the playing field if the battle is going against you. Like sending Amoongus in and using Clear Smog to reset a sweep, then Toxic stalling, using Clear Smog any time they try to set up. Just an example(And it won me a battle. Hee-hee-hee).

Answer 2

If sun is up, you're outta luck. You need an assault vest with max hp and 80 spd with +spd nature

252+ SpA Protosynthesis Flutter Mane Shadow Ball vs. 252 HP / 80+ SpD Assault Vest Tinkaton: 103-123 (27.5 - 32.8%) -- guaranteed 4HKO

Or max hp and 184 spd

252+ SpA Protosynthesis Flutter Mane Shadow Ball vs. 252 HP / 184 SpD Assault Vest Tinkaton: 103-123 (27.5 - 32.8%) -- guaranteed 4HKO

If sun isn't up, you're gonna get three shotted regardless

252+ SpA Flutter Mane Shadow Ball vs. 252 HP / 0+ SpD Tinkaton: 129-153 (34.4 - 40.9%) -- guaranteed 3HKO

252+ SpA Flutter Mane Shadow Ball vs. 0 HP / 252+ SpD Tinkaton: 103-123 (33.1 - 39.5%) -- 100% chance to 3HKO

With an assault vest, no defensive investment is needed if +spd nature

252+ SpA Flutter Mane Shadow Ball vs. 0 HP / 0+ SpD Assault Vest Tinkaton: 87-103 (27.9 - 33.1%) -- guaranteed 4HKO

If not +spd nature, then 116 hp evs

252+ SpA Flutter Mane Shadow Ball vs. 116 HP / 0 SpD Assault Vest Tinkaton: 94-112 (27.6 - 32.9%) -- guaranteed 4HKO

Or 104 spd evs

252+ SpA Flutter Mane Shadow Ball vs. 0 HP / 104 SpD Assault Vest Tinkaton: 85-102 (27.3 - 32.7%) -- guaranteed 4HKO
