Competitive is very luck based, but is great against Pokemon with the ability Intimadate. This also comes in handy when the opponent uses a move with additional effects that lower stats. Milotic is enough of a tank that it can take a hit from at least one grass or electric attack in order to utilize the weakness policy, so long as the opponent hasn't used anything like Swords Dance.
Nothing is funnier then poisoning another Milotic, and double-teaming while it tries to recover.
Milotic's greatest weakness is when Pain Split is used against it.
