Ah, Ludicolo. One of my favorites. Now I know Smogon banned Drizzle and Swift Swim, but Rain Dance is still useable.*
The Swift Swimmer (But only in Rain Dance)
- Giga Drain
- Ice Beam
- Hydro Pump / Surf
- Focus Blast / Hidden Power [Fight]
Item: Life Orb
Ability: Swift Swim
EVs and Nature: Modest
4 Hp / 252 Sp. Atk / 252 Spe
Standard Rain Dance abuse set. Giga Drain is primary STAB, and restores health. Very helpful when Life Orb reduces health every turn. Ice Beam is chosen as a reliable and powerful move, that can also destroy Dragons. Surf and Hydro Pump are secondary STAB. Hydro Pump is recommended for sheer power, although Surf is a reliable alternative. And the final move offers the same choice. Focus Blast can have enough power to obliterate Ferrothorn, but at a cost of lower accuracy. Hidden Power [Fight] is a much weaker, but safer alternative. In short, if you want power, go with the first set of slashes; if you want reliability, go with the second.*
Now here's a more gimmicky Rain Dance abuser:
The Swift Swimmer 2 (But only in Rain Dance)
- Seed Bomb
- Swords Dance
- Waterfall
- Drain Punch
Item: Life Orb
Ability: Swift Swim
EVs and Nature: Modest
4 Hp / 252 Atk / 252 Spe
Its not really "gimmicky", its just unexpected. Ludicolo has low Attack initially, so Swords Dance remedies that problem. Waterfall and Seed Bomb are STAB, that also gets good coverage together. Drain Punch rounds it out, and also restores health. This is a useful set that combines power with reliability, but also with unexpected-ness. (Is that even a word?)
Just ignore my post count, I've been a lurked for 2 years now and I know how to play Pokémon.
I need someone to teach ne how to RNG abuse and what programs to use. Please VM me!
