Panpour

Panpour, at first glance, seems completely outclassed, having low stats which are eclipsed by many other Water-types. However, there is one move in its arsenal that makes it usable. Nasty Plot allows Panpour to quickly boost its Special Attack stat without lowering its defenses, meaning that it can take a hit much more easily than more common sweepers such as Clamperl. Though not great, Panpour's movepool is also good enough for it to take advantage of the boosts it acquires. Overall, Panpour might not be the best Pokemon, but Nasty Plot certainly makes it a usable choice for almost any Little Cup team.
