In my latest actually successful team I used offensive DD Dragonite as priority and midgame pressure. Lum berry makes it a decent check to Techniloom and it can occasionally pull off a couple of cheeky kills thanks multiscale. I feel like his late game potential has kind of decreased but he's still a monster midgame, especially if you manage to keep rocks off your side.
