Ludicolo

Ludicolo is both a dangerous rain sweeper and a great special wall in NU. When given a single chance to switch in and a single turn to set up, it can shred entire teams to pieces within seconds. Its unique Water / Grass typing only benefits it, giving it excellent coverage, as well as handy resistances, with just its STABs alone. It also has an impressive Special Defense to work with, letting it take a more supportive role if needed. In addition, Ludicolo does not require excessive team support to function, having every tool it needs to sweep or wall right under its belt. Not all is well, though; for Ludicolo is heavily dependent on setting up Rain Dance, as it just isn't fast or strong enough without the rain up. This means that it is incredibly vulnerable on turns it attempts to set up, something that must be kept in mind when using it.
