I've been using Swords Dance+Baton pass on the ladder with some moderate sucess. It's amazing when it works out, but it's quite hard to pull off against more offensive teams, as Hawlucha is very frail. Still, it's amazing how it can catch people completely off-guard. Hawlucha's typing has very few weaknesses too, meaning you can easily get a recipient that resists them. For example, you can use Charizard X or just about any ground type to Baton pass into an electric move (remember you outspeed Thundurus and are immune to its Prankster thunderwave ;) ). Or maybe use Mega Mawile, who resists Ice, Fairy AND Psychic? There's a lot of possibilities.
