>>20620645I have one of my own, and I went for a +speed, 31IV Atk/Spd with Limber instead of Unburden. Hawlucha is fast enough in the first place, and those +2 Acrobatics without item are strong enough to take enough of the opposition on. I did invest a bit of his EV's too in HP. He usually gets that one turn in to get a Swords Dance up.
I also tried running Encore, but it hasn't got as much successful use from me. It is fun to lock Garchomps into Earthquakes though.
