Been a while, I must've used x defenses or something. But, Araquanid has water bubble. It doubles the base water attacks, which is actually calculated before the stab. I really didn't need to outspeed her pokemon. Araquanid is a decent tank, I just had to tank a little and keep myself high enough in defenses to stay alive. So, what happened was, I sent out araquanid, let it take a hit while buffing my defenses. Don't remember, but I think I may have healed, but it just on with tanking and getting my stockpile up. I don't particularly know if I used the stat boosting items, but I was able to tank a hit from most of her pokemon.
