This set gives Goodra more physical bulk, while still taking advantage of it's natural special bulk.

Ability: Sap Sipper
EVs: 252 HP, 252 Def, 4 SpD
Impish Nature
- Curse
- Earthquake
- Rest
- Body Press/ Outrage/ Counter/ Iron Tail
Curse is to increase power and physical bulk. I don't mind the speed drop since 80 base isn't much anyway. Sap Sipper is a good ability so you can't get seeded by Ferrothorn or Appletun. Earthquake hits Pokemon like Excadrill, Tyranitar, and Toxapex hard. If Goodra gets worn down after stacking Curses, then Rest is there along with a held Chesto Berry to instantly heal. Unfortunately, since Goodra can't learn Dragon Tail this gen, you may have to substitute it with Body Press for Ice types, or Outrage for a hard-hitting STAB move, but fairies like Mimikyu are common in BSS, so I wouldn't run that. You can sash Counter in there to surprise strong physical attackers. Iron Tail is another option too if you want to hit fairies super effectively, but the accuracy is a bit shaky.
This set is unexpected and can take people by surprise! I hope this set pleases you.
