Ferrothorn will be at least in the top 5 usage or top 3 at least. Funny enough if Ferro was in this gen it wouldn't lose any moves since knock off, toxic, and leech seed are eggs moves for it. Ferro will never be bad, look at National dex ou in Gen 9, it's top 2 usage which says something. It walls a good chunk of the ou mons that's for sure which gen 9 ou is clear lacking a good wall for both physical and special without Tera which Ferro doesn't really need to abuse it, only if it's a bad match up which Tera Water, Grass, Ghost, Fairy, are good Tera for Ferro . Has the best typing. Only thing Ferro lacks is recover which Game Freak needs to give it Strength Sap and then it will be good. But yeah Ferro is an important Pokemon and Gen 9 ou is seriously lacking something and it's this mon. Garg, Gliscor, and Zaptop cannot fill Ferro shoes
Strength Sap Ferrothorn is kinda horrifying. We don't need to give it reliable recovery too, it already has everything sob
