For in-game use something like this:
Mudsdale
Ability: Stamina
- Earthquake
- Body Press
- Iron Head
- Body Slam ( S / V Tera Blast if you have unique tera)
Use the super effective move. Simple.
Competitively, here’s a Smogon set:
Mudsdale @ Leftovers
Ability: Stamina
EVs: 252 HP / 252 Def / 4 SpD
Tera Type: Steel / Water / Ghost
Impish Nature
- Stealth Rock
- Earthquake
- Body Press / Stone Edge.
- Roar / Protect
Leftovers for recovery. Stealth Rock is a hazard. Earthquake is STAB. Body Press is to take advantage of Stamina, or Stone Edge to cover for flying types. Roar allows you to toss your opponents across the rocks. Protect is to scout and give more time for Leftover recovery. Tera’s are all defensive. Steel is a great defensive type. Water gives only two weaknesses, making it harder to break through Stamina. Ghost spin blocks. Use whichever one you need. Hope this helped!
