Physical Clauncher Clauncher @ Eviolite Ability: Mega Launcher Level: 5 EVs: 252 Atk / 172 SpD / 84 Spe Adamant Nature - Hone Claws / Swords Dance - Crabhammer / Waterfall - Aqua Jet - Rock Slide / Facade
Hone Claws boosts your attack and accuracy. Crabhammer is powerful STAB that appreciates the attack and accuracy boost from Hone Claws. Aqua Jet is priority STAB. Rock Slide is for coverage. Facade can be used instead as a surprise for if you're inflicted with a status condition. Swords Dance can be used instead of Hone Claws to double your attack stat. If you decide to go with Swords Dance, use Waterfall over Crabhammer for STAB that has better accuracy.
Shrimpy (Clauncher) @ Choice Scarf Ability: Mega Launcher Level: 5 EVs: 36 HP / 212 SpA / 12 SpD / 244 Spe Timid Nature - Water Pulse - Dragon Pulse - Aura Sphere - Sludge Bomb
Choice Scarf Special set. Mega Launcher boosts Pulse moves, other moves for coverage. Messy EVs because LC is odd XD
Have fun using this set! :))
