Hello there.
First, I want to say that, while I'll try to be as 'objective' as my game experience allows me to, I'm a human being, and thus, my opinion and subjectivity will have to be present somewhere in what will follow.
I love Tera. That was fast. I do think that Tera is a very good mecanic, and I agree deeply with what Vert and CBB have already posted here.
TLDR of my opinion for the lazy bummers:
Tera should not be restricted, and should stay allowed.
Now, as to 'why' I think this way. Why is Tera Preview a bad option imo? Why is Tera Blast not a real key? Why is Tera healthy in any way?
I'll try to give you all my humble experience on this matter here on out.
History bit (skip if you don't care about context):
First, as you can see on my little profile icon, I'm not top contributor, tournament winner, or social media ambassador. I'm deeply invested in my national community, as well as the leaking one, but then why do I come here to talk about SV OU?
Welp, I've had a very special relation to Tera this whole year. Last summer, when it was announced, I stated right after the first trailer ever showcasing the mecanic that I'd vote DnB if this was ever suspected (Dynamax was still fresh in our minds, so banning a main mechanic was not out of the question).
The game released, I played a lot of SV OU, and finally, this suspect came out. This was the first suspect I've ever had the faith to participate in, in my years of playing this game, simply because I judged the mecanic to be not only unique, but indeed very skillfull. And the Pao suspect confirmed that to me.
During both suspect (I think CBB stated the same somewhere), I've never dropped a single game on a 'Random Tera'. If I lost a game, it was because of me clicking too fast, misjudging the opp, or forgetting an option. Tera was never an 'X' factor to me, perhaps because I played it since the beginning of the Gen.
This mechanic, and Generation as a whole, forced me to step up my in-game, as well as building level, a lot more than the past two Generations ever did. Achieving both requs with my self-built teams allowed me to understand the meta way more, and I think some (not all) people who didn't play enough games in Gen 9 should take notice of how much encountering the metagame face to face, and learning the hard way, in game, how and when to Tera, is a very important skill, and is a big plus to competitive Pokémon.
Which leads us to :
Flashforward to WCup Qualifiers :
I had the chance to be an helper in Belgium's World Cup team, which will, sorry you guys, serve as a great example as to why I think lack of experience in the metagame generates misunderstanding of the mechanic, frustration, and thus, a ban-worthy feeling.
When I arrived on the Discord, I did a few testgames, and... well the level was cataclysmic, even for some very good players. They Tera'd T1 setup sweepers, sac'd important Terad wincond, or checks to some of my Tera threats. It was a one way massacre. I heard very often that 'Tera had to be nerfed, banned, restricted'. But after I spammed the hell out of their test games, and explained to them their Tera errors, they began questionning themselves, thinking more outside of the box, and taking fully their Tera into account.
We started building together, exchanged ideas on Tera users, explored the possibility of multiples types on pivots, spinners, sweepers, rockers (yeah alright basically Great Tusk, you got me), every single Mon we built with, and we could use Tera as a way to 'patch' certain very strong and threatening Pokémon (hum, Volc, hum). We had so much fun, we built tons of teams, and we tested all of them a lot, which led to improved results, and a very good R2 of qualifiers.
HOME meta dropped, we studied, we played a lot, a lot, a lot of games. And look at them go, they went into the main event, and didn't drop again, because they took into consideration, and as a central aspect, the question of using Tera, and of actually practicing it. Like stated by many others, it's not an auto win button, it has no intention of ever being such a thing, and is a very nuanced mechanic. I've seen many players, who's name I won't quote, but who'll recognize themselves, lose tons of matches in important tournaments because they just showed up, grabbed a team, and went into battle without much Gen 9 knowledge to back it up.
I invite those of you who didn't read
Mimikyu Stardust 's Doc to give it a read, what's explained there is so simple, but so extremely crucial, just like Tera itself:
https://docs.google.com/document/d/1tWPdrX0vXYaTqV9vpqsbQ1O8eS8TdhVqEwxYaMvN0og/edit. It may seem very 'well yeah, duh', but I assure you rereading it sometimes helps a lot in refocusing on the crucial aspects of a Gen 9 Game. Most importantly tho, everything that's written here should be practiced. This all becomes muscle memory, at some point.
As for the matter of the actual suspect test, I won't repeat what
Vert,
njnp and
CrashinBoomBang said (linked their posts), it would be a waste of time.
Tera raises indeed the skill level of the metagame, and forces you to actually play the Gen, instead of being a penultimate previous Gen player who just loads up a random team in SCL and performs well.
I just think:
- Banning Terastallization outright would be a terrible idea imo. The mechanic brings so much depth into the metagame, and has been such a clever and unique principle that it would be to me like banning items at this point.
- Tera Blast is something I'd rather argue about on a separate thread, although I'd like to point out that... action on Tera Blast should imo be taken before any action on Tera, since banning Tera basically makes this useless, aside from like one Mon which likes to run it as a STAB/Coverage.
- I've only experienced, like many others, Preview in Drafts, but I think as a whole, this doesn't solve a lot of issues, and bring a new bunch to the table. Whereas before, you could force a Tera by scouting it, when the opp was sure to have the surprise advantage, making scouting skills even more useful, it will now realy be a 50/50 at each action. The opponent knows you know their types, and as such, more turns of inactions, or 50/50 Teras could occure. It could also very well create a metagame without the Chestnaughts/Moltres-G of this world. It would be in the best interest to play more standard Mon with more standard Tera types, as the surprise factor would be out of the question. Those are all suppositions anyway, so no need to take them into account, we don't know what would occur.
- What I do think is that preview removes the sole beauty of Tera, being the meta knowledge and tier engagement, while bringing nothing to the table, as a lot of people would still complain if this was applied. I do think an in-between is not a good thing, and that preview is the first step to the downfall that is outright banning Tera.
As for the format/formulation of a potential suspect test, Amaranth already said everything
in their post. It's a very important part of tiering, so I'll appreciate if everything is formulated correctly. What
this post suggests is also very good, I'd recommend reading it.
Thanks for reading my rumbling, I'll probably post further opinions once the public thread releases. I tried to stay short and keep the main points of my experience into this. I really think Tera brings a endless world of possibilities, and will help make the Generation more unique, competitive and interesting than ever before (above Gen9 that's for sure).
Again, everyone can have their own opinion, mine after building and playing TGs a ton in World Cup is that Tera is fine as is, but please do stay respectful to one another, especially in the public thread
(I'll post a bit more later on, I'll answer some well written post that I thing deserve more attention/credit, from both sides, and will continue reading this thread in search of those

)
