Ludicolo

Ludicolo is a strong rain attacker, firing off powerful Water-type attacks in order to punch holes in the enemy team. It has access to Fake Out, which is a useful move for disrupting opposing strategies, and under rain, Ludicolo is the fastest Fake Out user in the metagame. Immunity to powder moves can be handy, making Ludicolo unaffected by Spore and Rage Powder, which allows it to get around Amoonguss, an annoyance to rain teams. Ludicolo has Grass-type STAB coverage and can deal with traditional rain checks such as Tapu Fini. However, Ludicolo lacks useful resistances, has mediocre bulk, and falls easily to more powerful attacks. Additionally, it is very dependent on rain, thus being limiting towards teambuilding.
