Superpower for Contrary boost in both defense and attack by one stage. Moonblast for fairy STAB. You can use Mystical Fire or Earth power for coverage and to hit types it’s weak to for super effective damage like Steel, Ice, Poison, and Rock.
You can also use Zen Headbutt or Iron head for physical side and as coverage. You can get a good switch in on Kingambit since it resists dark and even with this bulky set it can outspeed and use Superpower (4x Effective against Kingambit)
