I think I'll bring up a pretty underrated and somewhat irrelevant pokemon because there's nothing to do and I am out of hot pockets.
boner joke here (Marowak) @ Thick Club
Ability: Rock Head/Battle Armor
EVs: 252 HP / 252 Atk / 4 SpD
Adamant Nature
- Bonemerang/Earthquake
- Stone Edge
- Knock Off
- Double-Edge/Stealth Rocks
Thick club is essentially a huge power boost that gives marowak a nice and meaty maximum 568 attack stat.
252+ Atk Thick Club Marowak Bonemerang (2 hits) vs. 252 HP / 0 Def Vileplume: 296-350 (83.6 - 98.8%) -- guaranteed 2HKO after Black Sludge recovery
252+ Atk Thick Club Marowak Bonemerang (2 hits) vs. 252 HP / 0 Def Audino: 294-348 (71.7 - 84.8%) -- guaranteed 2HKO after Leftovers recovery
252+ Atk Thick Club Marowak Stone Edge vs. 252 HP / 252+ Def Crustle: 214-252 (62.2 - 73.2%) -- guaranteed 2HKO after Leftovers recovery
However, marowak does have its drawbacks, that being that it must hold thick club in order to be able to stand out; meaning it wont be able to use anything like leftovers or assvest to help its alredy bad special bulk.
