I´ll try to help you.
First Superpower( If you got access to a Gen IV movetutor)/ Brick Break over Pursuit, otherwise you will get walled to much. Milotic looks fine.
Standart Garchomp works always, or you try timid Gengar@ Sash, Shadowball/Thunderbolt/Fokus Blast/Destiny Bond as a lead.
Pretty standart and nothing special, but at least it works.
