Psyduck

At first glance, Psyduck looks vastly inferior to the majority of usable Water-type Pokemon. Psyduck, however, has two things working for it that sets it apart: access to Cross Chop and its ability, Cloud Nine. Cross Chop allows Psyduck to threaten Snover, who walls most other Water-types easily. Cloud Nine, however, is the main reason that Psyduck is a viable option in Little Cup play. With Cloud Nine, Psyduck is able to stop weather-based teams cold. Furthermore, its respectable base 65 Special Attack and base 52 Attack stat allows Psyduck to retain general utility if the opposing team does not have a weather abuser.
