This was Gogoat for a while, but the team has no Stealth Rock without it. I chose Perrserker as it is an Ice and Fairy Resist. It is Spdef to try and handle Calm Mind Carbink better. If the opposing Carbink is just ID + Body Press Misdreavus will beat it. If it is Calm Mind + Moon Blast you go Perrserker and Iron Head, Tera Ghost is just in case it is CM + Moon Blast and Body Press. The Speed lets it outpace a paralyzed Charizard. Protect + Leftys helps longevity. Also Para spam + Iron Head helps cheese things it otherwise could not beat.
Gogoat is another really good wincon for this team if you want to try the team rockless, which might be ok right now because of all the boots spam. Tera Water actually adds a decent Charizard check while giving the team a much-appreciated Water resist. Rock Slide + para spam is also some hot cheese.
