Sap Sipper Saws on a Sun team works somewhat. It bluff Chlorophyl, so it can get a free attack boost on a Spore and dent things early on without having to sack half of its HP. Sawsbuck is a major threat, as noted, as really only steels beat it. With Chlorophyl, it is dang near unstoppable if it get Belly Drum off. With a Lum Berry it even beats Sableye since Sawsbuck lures it out instead of switching in on it. Ferrothorn is still a pain, but I'm not sure how prevalent in the meta he will be. Plus, Sun teams. I'm really lovin' him.
Cresselia with Cosmic Power+Stored Power is pretty great. With either Rest or Moonlight for Recovery, it can keep healthy and even take some critical hits and recover the damage. In the sun, it has Boosted Moonlight, but with Rest, it avoids the timer that is Toxic, but with Walls almost non-existent and being immune to TSpikes, Moonlight is pretty viable. HP[Fighting] can be used to hit Dark types, or Calm Mind can get more boosts while boosting SAtk.
Thundy-T seems like it would be deadly with STAB Thunder and Hurricane coupled with its 101 base Speed. Give it Agility/NP and watch it go.
Sableye seems like it would be pretty good. It can burn/Sleep almost anything. The only thing with Sleep immunity that would be good is Primape, but Sableye is immune to Fighting and can just burn it.
Sadly, I've only got to battle once, but it was fun.
