In my younger years and even when I got back into Pokémon after years of not playing, I used to go for brute force alone. The higher the number under "Power", the better.
But as I played on and joined challenges, I slowly realized how wrong my play style was.
So I slowly started relying on status changing moves as well. Ever since then, I've used moves such as Thunder Wave, Attract, Confuse Ray, Screech, Swords Dance and so on and so forth to suit my needs.
And I always include such moves when planning out teams for challenges. Or well, at least I try to xD
