Ludicolo

Ludicolo is a niche pick on rain teams in RU as a Swift Swim sweeper due to its ability to threaten annoying bulky Water-types such as Gastrodon, Suicune, and Milotic with Giga Drain. It also has perfect coverage to hit the tier for at least neutral damage, making it sometimes difficult to deal with it. However, Ludicolo is very dependent on rain to make up for its mediocre offensive presence; otherwise, it is very easy to check and revenge kill. Even under rain, Ludicolo still struggles against specially defensive Pokemon that are not weak to its STAB moves, such as Assault Vest Reuniclus, Umbreon, and Porygon2. Many Pokemon can also revenge kill Ludicolo such as First Impression Golisopod, Trace Gardevoir, and Choice Scarf Flygon, even under rain. Ludicolo is also difficult to fit on many rain teams, as they prefer other Swift Swim sweepers like Kingdra and Kabutops or teammates such as Tornadus and Noivern that can handle problematic foes like Toxicroak and bulky Grass-types.
