Is it good for battles?

It'd make more sense if you actually gave us details such as each Pokemon's abilities and natures so we can help. For example, a Water Absorb Politoed works different than a Drizzle Politoed and a Rough Skin Sharpedo is virtually useless especially in comparison to a Speed Boost one. Natures matter so you can determine if you want the Pokemon to be physically or specially defensive/offensive
