What if Torterra learned Shell Smash? That'd be pretty fun, I think, and Torterra is definitely underrated in the current meta. First of all it would obviously (I would think, anyways) eliminate the Rock Polish set (because who uses Rock Polish Carracosta? :p) Anyways, after 1 Shell Smash, Torterra only fails to 2HKO a handful of Pokemon (if it's using Wood Hammer / Stone Edge / EQ), most notably Tangrowth and Exeggutor. This would make fire types like Emboar and Entei decent partners, covering each others' weaknesses (although Torterra is neutral to Water moves.) Infact, Torterra as a part of a FWG core would be excellent, something like Entei or Emboar/Torterra/Qwilfish, maybe with Uxie or someting else with access to Thunder Wave since even after +2 it doesn't outspeed everything. Despite it's new move, I can imagine the Tank sets that are onsite still being used, albeit not as often. And something I was thinking of earlier, What if Sigilyph learned Nasty Plot?
