To summarize around 80% of people’s thoughts right now…
Terastalization has been cited as the hallmark of the generation, and quite possibly the most defining trait in our metagame to date, both for better or for worse. On one hand, Terastalization’s defensive attributes are known to be beneficial for their ability to reinvigorate the defensive roles of several Pokemon to combat the slew of offensive exchanges defined by a power level as high as the current generation, being reinforced by the tier’s ongoing struggles in accompanying for solid utility options, and allowing for highly unprecedented forms of role compression in the teambuilder. Examples among these can be seen in ordinary defensive Pokemon such as Unaware Skeledirge and Ting-Lu with Tera Water, extending themselves to checking threats such as Excadrill and Gyarados in pinch situations otherwise barred off by their weaknesses, or Galarian Slowking using these benefits to escape trouble against Dark and Ground-types that would limit its pivoting capabilities long-term, albeit not without the cost of utility in other areas upon transitioning which can force serious considerations, like when acting as a team’s check to Enamorus.
For all the positives Terastalization brings to the tier, there has also been a significant number of negatives brought upon by the grievances of the playerbase, as Terastalization’s offensive potential is not to be understated in the slightest. Mostly seen in the Adaptability-like boost it provides to several offensive Pokemon, wallbreakers such as Enamorus, Aegislash, and Latios are pushed into territories of being nigh-impossible to withstand, while said examples and more are made no easier to deal with through the ability to manipulate their resistances to attacks at a whim, thus becoming much better equipped to survive interactions normally planned out against them. As a result, many of the best defensive Pokemon in the tier are also seen as highly inconsistent at handling most of these threats throughout the game, often by folding to the sheer power of boosted attacks outright, or being easily picked off by a surprise option allowing them to bypass this, being forced to act in a barrier of respect that consists of far greater boundaries. This overpowering dynamic can be further reflected in how it affected previously banned Pokemon as well, notably Kommo-o, Garganacl, and Baxcalibur, all of which had their offensive capabilities put several steps forward from being able to rewrite their defensive integrity to a major degree.

Tera Fairy - Heightens STAB Moonblast on Specs and Scarf sets, allowing the former to more easily muscle past Pokemon such as Gastrodon, while making the latter far more effective at cleaning offensive teams that rely on outspeeding it in a vacuum.
Tera Ground - Boosts the power of Earth Power significantly, allowing it to easily muscle its way past checks like Skeledirge and Assault Vest Galarian Slowking, additionally turning Enamorus’ Stealth Rock Weakness into a resistance.
Tera Ghost - Provides a complete immunity to Seismic Tosses from Blissey, as well as resistances to Pokemon like non-AV Galarian Slowking, which is especially notable for turning them into complete fodder with Sub CM.

Tera Dragon - Allows Draco Meteor to pummel neutral walls like Slowking and Tyranitar with ease on Life Orb or Specs sets, can also remove weaknesses to types like Dark and Bug in a pinch.
Tera Electric - Provides great neutral coverage in conjunction with STABs against targets like Aegislash and Clefable, while tearing through defensive Celesteela and Tapu Fini.
Tera Steel - Provides a poison immune on Calm Mind + Stored Power sets, while also giving resistances to Fairy, Steel, and Dragon to limit revenge killing attempts.

Tera Fire - Sheds the Fire weakness by turning it into a resist against revenge killers like Cinderace, while also providing a burn immunity against Mega Sableye and Skeledirge. Fire STAB in Tera Blast also most notably eviscerates Buzzwole and Skarmory at +2.
Tera Electric - Outside of 2HKOing the previously banned Dondozo, Tera Electric also easily breaks walls like Slowbro or Alomomola at +2, while retaining coverage for Flying answers and even providing extra resistances against them.
Tera Steel - Makes Bullet Punch significantly stronger on Swords Dance and Choice Band sets, allowing the former to reach absurd feats like OHKOing Blaziken at +2 after slight chip, as well as revenge kill threats like Moltres-Galar more effectively with the latter.
There are examples of more precise interactions which can be made further down the VR, but I believe said point is made adequately as it is.
Defensive aspects of Terastalization, while less appealing at first glance, are also worth a mention as part of an offensive weapon in its own right, and can indeed serve as the main selling point for several Pokemon on the other side of the tiering coin too, this ranges from niche, albeit underexplored examples in Ceruledge, being given an arguable breath of fresh air for the take of a classic defensive setup sweeper with Bulk Up - types such Grass giving it a new lease of life against common roadblocks like against Water and Ground-types, to more extreme and centralizing examples in base Latias, a prime example of a Pokemon almost entirely bent on the viability of Terastalization, yet made into one of the most threatening Calm Mind sweepers alongside its Mega Counterpart, with types such as Poison and Steel being prime examples to negate common weaknesses while minimizing would-be downsides in tandem with its natural traits.
Overall, Terastalization remains an incredibly contentious topic in competitive play, while our metagame and its given context remains no exception to this. Followed by the results from our recent community survey, events leading up have laid the groundwork for a rather unexpected turn of events, albeit one with potential to shift tiering premises immensely. With this in mind, the council has ultimately decided to first put the Terastalization dispute in UU to rest once and for all.

You must use a fresh account that begins with the given prefix for this suspect test. That prefix is NDUU9TERA. For example, I could signup and qualify with the name NDUU9TERA Arishem.
- You may not impersonate or mock another user with your account name. If there is any slight hesitation, you're probably better off picking a different name. We reserve the right to null your voting requisites if you are found impersonating or mocking another user with your account name. Moderator discretion will be applied.
- If you are found trying to manipulate voting requisites in any way, you will be met with a harsh infraction. Manipulating voting requisites ranges from faking your screenshot to asking another user to forfeit.
- The aspect that's being suspect tested, Terastalization, will be allowed on the National Dex UU ladder for 2 weeks so that we can properly assess its position in the metagame.
