Help with Purple Team? (sacred gold / storm silver)

As title says, I'm doing a Purple Only run of Sacred Gold (drayano's HG hack).

I am wondering if somebody can give me advice for team composition, to build the most balanced/powerful team possible.

Any ideas for other purple mons to use? The picture shows the pool im working with so far (Staryu of course becoming purple after evo so still counts!)

Maybe could use Sableye, Nidoking, Weezing... I'm not sure.

Any tips for this team?
