If we're not gonna ban Tera as a whole, IMO not a single mon in Ubers deserves to drop to OU, and as a matter of fact Gliscor, Kingambit and Gholdengo should all still get suspected and (hopefully) get banned. If we're banning it on the other hand, the only mons that could realistically drop and be fine in OU are Regieleki, Moon (I guess it could be manageable without Tera? Not so sure as of yet tbh) and MAYBE Volc. And yeah, I believe that the legendary Trio of assholes mentioned above should still stay banned, if we end up actually banning them after the sus tests. Gholdengo's main problem is Good as Gold, Kingambit's is Supreme Overlord + Sucker Punch creating a toxic environment of guessing games that award bad plays, and we all know what Gliscor's problems are, so Tera shouldn't be much of a factor in this decision.
I have a question regarding the potential ban of Tera though, what's gonna happen to Ogerpon? I guess we'll end up banning the Embody Aspects since they are completely dependent on the Tera mechanic, but will this make Firepon and Waterpon any less OP than they are now?
