Presenting: Super Colo Bros! They're awesome cleaners, as they're great at Sweeping!
Physicolo
Ludicolo @ Muscle band
Ability: Swift Swim
EVs: 252 Atk / 252 Spd / 4 HP
Adamant Nature (+Atk, -SAtk)
- Nature Power (Aka Earthquake)
- Seed Bomb
- Waterfall
- Swords Dance // Ice Punch // Zen headbutt // Drain Punch.
A Physical sweeper. You set up with SD, then use two powerful Physical STABs along with the ever Useful Earthquake (via Nature Power) to inflict damage.
Alternatively, having another attack instead of Swords Dance could save your skin. Ice Punch, for example, for those Nasty Flying types that'll destroy you. Zen headbutt deals with Poison types that aren't hit by EQ (Crobat). Drain Punch has a lot of SE strengths.
Specolo
Ludicolo @ Wise Glasses
Ability: Rain Dish
EVs: 252 SpAtk / 252 Spd / 4 HP
Modest Nature (+SpAtk, -Atk)
- Surf/Hydro Pump/Scald
- Energy Ball
- Ice beam
- Focus Blast
The same set, but special and without a power booster. However, Ludicolo's special attack stat is higher than its Attack stat anyway.
Ice and Fighting is a fantastic combination (excellent normal damage coverage with fantastic SE coverage), and Energy Ball is the strongest STAB Ludicolo has. The other possible STAB can be chosen from Hydro Pump, Scald or Surf.
Hydro Pump is the most powerful, but I personally hate moves with lower accuracy, so I don't use it. Surf, which I use, is useful ingame and is a powerful and reliable attack competitively. Scald is a little weaker but does provide a chance of burning the opponent, particularly useful for stopping flyers and Bugs from doing too much harm.
And the Forecast today...
Ludicolo @ Icy Rock // Heat Rock // Damp Rock *Focus Sash
Ability: Own Tempo
EVs: 252 HP / 252 Def / 4 SDef
Calm Nature (+Def, -Atk)
- Hail // Sunny Day // Rain dance *Hail
- Focus Blast *Rain Dance
- Ice Beam // Synthesis // Surf *Sunny Day
- Giga Drain
This Ludicolo is very useful for teams trying to closely follow Smogon's word and needing a way to set up their weather. Ludicolo can learn three of the four weather inducing moves making him very useful indeed.
The set Ludicolo uses depends on what weather you need.
The Hail Set uses an Icy Rock, Hail, Focus Blast, Ice Beam and Giga Drain.
The Sun Set uses a Heat Rock, Sunny Day, Focus Blast, Synthesis and Giga Drain.
The Rain set uses a Damp Rock, Rain dance, Focus Blast, Surf and Giga Drain.
Alternatively, there is a set using all three weather inducing moves, useful if you want a team of various Pokemon that need weather conditions to become super strong. This set is denoted by the moves/items after the asterisk in the example.
