Current one I've been using with a lot of success on Skarmbliss' PO Server is this, Draco Meteor, Surf, Dark Pulse and Protect, it is paired with Burungeru seeing both can work well in both TR and Tailwind in this VGC and Sazandora can check Ghost types and resists dark and electric type attacks.
All sets have Dark Pulse, either Draco Meteor or Dragon Pulse, Surf/Fire Blast, and normally Protect or another offensive attack.
Net Ball looks like the color scheme on both fit really well with being primarily blue with some black/dark colors. The RNG for flawless IV pokemon/near flawless pokemon seems like it is much easier on BW than what it was in 4th Gen, other than the fact that you have the somewhat random nature generator which was a pain for Mystery Gift pokemon, but you can at least use synchronizers now.
