Clobbopus doesn't have great stats overall, but has good Physical Attack and Defense, which are good in LC, at 68 and 60 respectively.
Clobbopus @ Eviolite
Ability: Limber / Technician
EVs: 212 Atk / 58 Def / 58 SpD / 180 Spe
- Power-Up Punch / Brick Break
- Detect / Bulk Up
- Liquidation / Waterfall
- Ice Punch
This is quite a defensive Clobbopus, but it can pack quite a punch! The Ability is Limber which can be pretty clutch sometimes, but Technician is if you choose Power-Up Punch over Brick Break. 212 Atk makes it really strong, and equal Def and SpDef spreads, boosted farther by the Eviolite. The Jolly Nature let's it invest more EVs in Attack whilst still boosting Speed.
Onto the moves.
Power-Up Punch and Brick Break are both STAB, but it depends on whether you want an Atk boost over stronger BP or not, as well as Limber vs Technician. Detect is Protect but less PP, and Bulk Up boosts Atk and Def. Liquidation and Waterfall are both solid choices for a Physical Water move, Liquidation is 5BP stronger and 20% Def drop chance, and Waterfall might Flinch. Ice Punch is because it doesn't really have much other coverage.
Have fun using this set!
