Shuckle does 0 to Sticky Hold Muk/Swalot, Spikes fucks it, Sub Aggron eventually breaks it, Rain teams usually ohko it (Even 252 hp/sp def Shuckle can't take a surf from rain Gorebyss), any Taunt user laughs at it, etc etc etc
Shuckle is just bad, I don't see any well build team having trouble against it.
I already said what I think about Kingler/Granbull (Ban when?)
I think Fearow is beast, like a weaker version of Dodrio but with same speed and still enough power to clean up late game. I've seen a lot more Aggrons being used since Fearow became NU, even some mawiles and other weird shit.
Also, how is Claydol even NU? Lmao that thing is so annoying, even more when people put fucking Trick on its moveset.
Anyways, first thing to be discussed should defo be Kingler for the reasons Forfi mentioned.
