The biggest things I've been seeing are a surge in Heatran, Tapu Bulu, Rotom-W, Celesteela, and Toxapex. Heatran runs rampant now that its best check is gone, and it's best partner Tapu Bulu has one less thing it has to check and can be more reliably switched into Ash-Gren and Lando-T. Rotom-W and Celesteela are great now because their Ground immunity actually means something again. Toxapex naturally compliments Celesteela, as well as stall which doesn't have to worry about how to break through defensive Zyggy anymore. Toxic Spikes I feel aren't as good now because of the popularity of ground immunities again, as well as Pex everywhere to absorb them.Since it's been like 20 days since the Zygarde ban, the meta's still fairly fresh. Though I was wondering, what are some current Pokémon that seem more viable or less viable since the departure of the snake?
A sleeper threat I see is Charizard X. The DD+FBlitz+EQ+Roost set takes advantage of the BuluTran surge, and fairly reliably takes on much of the top-used mons besides LandoT (which it does outspeed at +1, but Intimidate sucks). That's just my quick thoughts on what I've been seeing about.
