I don't know much about MFA, but it looks pretty similar to OU with the exception of some things like Swellow, Guzzlord, and Goodra thrown in there.
No surprises in the Eternal Pokemon stats, you have the two Steel overlords, Lando-T, and then some common threats on offense and balance like Togetic-E or Cranidos-E.
Type Optimisation is also largely what you would expect. The almost busted things have the highest (I think Hariyama and Zangoose are going to be nerfed, if they haven't been already.)
I know nothing about Optimons, but it looks like Primarina got a pretty good buff.
The ATT stats really show that the new terrains shake up the metagame a lot. Unfezant in first is a little surprising to me, but I guess Elevated Terrain is a good choice because it doesn't benefit grounded opponent. Hawlucha is, unsurprisingly, high in usage because of it's potential on every team using a Terrain seed. Moltres is very high in usage because it benefits from Elevated terrain, I guess. Tapu Koko is the second highest usage terrain setter, unless Diancie is? But I thought Regirock set Rocky Terrain and Fini definitely sets Misty, so idk. Salazzle is also up there, so the Poison terrain was popular as well.
Those are just my quick thoughts on the usage stats.
