Potential Leads:
Clefable/ninetales + Pheromosa: Start off with those two, and if there is a weather setter on the opposing team, switch in ninetales to set hail and use blizzard. Switch into cresselia and lunar dance when pheromosa's or blacephalon's hp is low.
Clefable + Blacephalon, high damage, follow me strategy.
