Cherrim

What sets Cherrim apart from other Grass-types is its unique ability, Flower Gift, which raises its Attack and Special Defense stats in sunlight. A few decent support moves such as Aromatherapy, Grass Whistle, and Leech Seed, not to mention Cherrim's above average defenses, make it a decent Sunny Day supporter. However, Cherrim is not as fast as it would like, and also has a pretty shallow movepool, greatly limiting its potential in battle. This makes it good for only one thing: Sunny Day. Honestly, if you don't use Cherrim with Sunny Day, don't use Cherrim, as it is otherwise worthless.
