I think that Flygon takes one of the top spots. Having played in 3 states over the past two weeks I saw a LOT of Flygon especially among top players. Very strong and very consistent. I didn't see anyone playing FlyJolt, but had more variants like Royalty (Fly/Queen) or just pure Flygon with various techs.
Metanite is still easily one of the best.
I saw a lot more Speed Ban than Bandoom. With Lati-lock being reasonably common folks found other things to do with Banette ex.
Delta / RaiEggs is still pretty popular and a good strong deck ... but it seemed to have trouble with Flygon in the local metagame and so didn't do as well.
Flariados is nasty and I played 2 of them but it just didn't seem up there with Flygon and Metanite.
Muk Man was at NC States last weekend and he and I chatted for a bit. He played a Super Stantler variant but didn't do particulary well that day. Ryan V, was playing Bantler, a Stantler / Banette deck that was just plain mean, but he had some troubles at NC States too. I like SS, especially Ryan's version, though I would classify his as more of a Banette variant. However SS strikes me as an anti-metagame deck and thus almost inherently prone to inconsistency since the metagame changes a bit from event to event.
Only one guy in one of the three events ran MewTric that I’m aware of. Consistent maybe, but probably not one of the BDIF anymore.
Did not see Fusion, StingRay, or any Shiftry decks ... though my wife was going to run a Shiftry ex (cg) one had she been able to attend.
I would put Flygon & Metanite in Tier 1 (voted for Flyjolt since it was the closest). Delta, Boom, & Flariados in Tier 1a ... they are good and have a shot at winning but Flygon and Metanite are usually better.
