Gliscor @ Toxic Orb
Ability: Poison Heal
EVs: 244 HP / 252 SpD / 12 Spe
Tera Type: Fairy
Careful Nature
- Earthquake
- Swords Dance
- Facade
- Roost

Both lack the ability to really touch you, with the best option being Tera + Haze from Toxapex. In return, you can boost up and drop them both with EQ/Facade. While Defog+Taunt Gliscor might also do well vs this core, its just going to stalemate Lando rather than actually keep Rocks off.
