I dunno, I've been using a bulk up/drain punch/bullet punch/pyscho cut, experimented with both bulky and just max offensive spreads.
It's been fairly effective as both a lead and a late game sweeper, but then again I'm only around 1500 right now.
I paired it with a specially defensive mandibuzz to absorb the psychics coming it's way, and a defensive rotom - H as a status absorber/burn spreader/fuckyoutalonflame.
