If you could all please format your additions to look like the one below (i.e., DPP sprite, link to DPP analysis, Type, Base Stats, and Ability, followed by the paragraph), it would make my job of organizing all of the write-ups at the end easier, just sayin'~
Ludicolo
Type: Water / Grass
Base Stats: 80 HP / 70 Atk / 70 Def / 90 SpA / 100 SpD / 70 Spe
Ability: Swift Swim / Rain Dish
While it might not look like much, Ludicolo is a top threat in the rain. It's unique Water / Grass typing offers good offensive coverage, resisted only by Dragon- and Grass-types, which Ice Beam hits super effectively. Usually, Ludicolo will set up rain to power up its Surf or Hydro Pump while doubling its Speed thanks to Swift Swim. Although normally a special attacker, Ludicolo can also run a surprise Swords Dance set that punishes Blissey switch-ins, though it needs Rain Dance support from a teammate to function optimally. Resistances to the common Earthquake, Surf, and Bullet Punch provide it with several opportunities to set up rain or a Swords Dance throughout the battle. Once Rain Dance's timer runs out, however, it's a sitting duck for any powerful physical hits from faster sweepers.
Smeargle is my next pick, btw :3
