>>54700421>>Espathra (no more tera blast)Still has Dazzling Gleam for Dark types, which is just about the only thing stopping Stored Power sweeps. Of course it now is still weak to Sucker Punch.
>>Annihilape (no more defensive tera)It’s honestly hardest to say if Annihilape needs Tera to be broken or not. You can technically get a free RF boost with good timing of Tera and can avoid things like Specs Shadow Ball from Dragapult, but that’s about it honestly. It has great stats, a great typing, and STAB Rage Fist.
>>Chien-Pao (no more tera dark crunch spam or defensive tera)Absolutely did not need it what so ever. Chien-Pao is a frailer Zacian with dual STAB, priority, and an ability that’s always active.
>>Regieleki (no more tera blast)One of the few things definitively broken by Tera (Blast)
>>Volcarona (no more tera blast or defensive tera)One of the few things definitely broken by Tera
>>Ogerpon Hearthflame (no more tera form)Even without its Tera form, she’d still be a great Pokemon. She still has a x1.2 boost to all stats and with Mold Breaker + Play Rough is actually extremely hard to wall.
>>Roaring Moon (no more tera flying acrobatics or tera dark CB knock off)Still would probably be problematic now that it has Knock Off and also not competition with Baxcalibur. Still hits like a truck when it has x1.3 from its ability and x1.5 boost from Dragon Dance.
>>Kingambit (no more defensive tera)Would probably still be broken because its a fucking Bisharp evolution with a really great ability in SO.
>>Ogerpon Wellspring (no more tera form)Doesn’t affect it that much too be honest. It would have a weaker Ivy Cudgel, but otherwise it has the worst Tera Form of the Ogerpons.
Basically, only Pokemon you’d surefire save with Tera ban are Regieleki and Volcarona. You could argue for Annihilape or Espathra being broken by Tera, but could be broken on their own.
Rest are definitely too much for OU with or without Tera.
