Swords Dance (Mudaimer) @ Gaia Berry / Leftovers
Ability: Abnormal  
Level: 50  
Tera Type: ???  
EVs: 52 HP / 4 Atk / 204 Def / 156 SpD / 92 Spe  
Impish Nature  
- Swords Dance  
- Mighty Blow  
- High Horsepower  
- Protect  

Mudaimer's niche compared to Snorlax comes from its much greater speed, higher Attack stat and ground STAB. Mighty Blow hits most Pokemon for full damage after a Swords Dance. High Horsepower is a secondary STAB that hits the Rock and Steel types that resist Mighty Blow super effectively. The EVs give it a HP number divisible by both 4 and 16, letting it get the best from both Gaia Berry and Leftovers, with the Def EVs hitting a jump point, enough Speed to outrun Kolbolt in Tailwind and the rest in SpDef.

Ability: Abnormal  
Level: 50  
Tera Type: ???  
EVs: 4 HP / 228 Atk / 252 Def / 20 SpD / 4 Spe  
Adamant Nature  
- Fake Out  
- Mighty Blow  
- High Horsepower  
- Crunch

Assault Vest Mudaimer serves as more of a support tank than a late game bulky cleaner. Fake Out provides priority and lets it support its teammates. Crunch hits Wizareetin, Matakoda and Illophyr for super effective damage, who could otherwise wall Mudaimer.

Pairs well with: Matakoda, Sneasler, Wizareetin, Illumise
