Of the 8 pokemon that were unbanned, only Meditite, Vulpix, and Carvanha remain.
Of those three I honestly only feel Meditite is the questionable one. Its big check Gligar is gone and Ice Punch's slot can be better filled with other moves now. It has pretty much three deadly sets, Eviolite, Scarf, and LO. All of which have the ability to check their respective counters/checks with the right moves. You can EV it to survive Misdreavus's Shadow Ball, an itemless Fletchling's Acrobatics, and a Spritzee's Moonblast with Eviolite; use Thunder Punch for Slowpoke, High Jump Kick for Vullaby, Poison Jab for Spritzee (ZHB from Eviolite can even 2HKO >50% of the time with SR), Return for Elgyem. You can even use Baton Pass to escape from Wynaut. It's just surprisingly hard to kill especially since it can get psuedo recovery from Drain Punch as well. Fake Out + Bullet Punch are still beautiful for all those annoying Sturdy + BJ Pokemon as well as just being general priority.
Drought took such a boon with the 5 turn nerf, as well as making lots of new enemies with Fletchling's Priority Acrobatics and Generation 6's new mechanics for Grass-Types and Overcoat, both of which grant an immunity to Sleep Powder and Stun Spore. If your sun team utilized Shadow Tag from Wynaut or Gothita even that was somewhat significantly nerfed due to Ghost-Types now being able to switch out of it. That's not to say sun isn't viable, but it is probably better to lean more towards balanced than hyper offense for sun teams. I don't particularly feel like Vulpix is enough of a problem to be near suspected, especially due to its low usage at the moment, but Sun boosted Fire Blast is still damn strong.
Carvanha is annoying with Life Orb/Focus Sash, and Destiny Bond, but I'm not exactly an expert on it since my teams tend to always be well protected against Carvanha by default.
