I wanted to take the time to briefly highlight a couple sets I have been playing around with. First, Porygon Z.

Porygon-Z @ Choice Specs
Ability: Adaptability
Tera Type: Ghost
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Tera Blast
- Trick
- Psyshock
- Tri Attack
As one of the few powerful Normal special attackers, it was a candidate to test the limits of Tera Blast. As most people familiar with this mon know, its main STAB is often the 80 BP Tri Attack. Tera Blast is the same base power, but you can trade hax for the ability to switch STAB types while choice locked. Ghost Tera on Normal is also useful defensively since the types cover for each other's weaknesses. Full disclosure, I'm not done testing the concept. I still felt it was time to get it out there.
This set is a wallbreaker. The speed tier is kinda slow for OU, so I put it on webs for power rather than trying to make scarf work. I have tried scarf Indeedee to some success, but I wanted to make full use of the wallbreaking power of Z here. In the process, I realized that I don't play webs nearly enough to know it, and therefore, don't really know how to play it well. I know HO, but not this form I guess.
I have a couple lower ladder replays that show the use Tera on Porygon-Z pretty decently. One in particular is rather a poorly played game I'm not proud of, but it still showcases the base concept well enough.

With this, I can say that I have now experimented some with 2 of the 3 Normal special attackers I wanted to try out with TB tech. While I think Porygon-Z is probably still niche because of its speed tier, this can work in OU. The one I need to test now is H-Zorark. I think that one will be the best because of the speed tier. Anyways, I encourage people to play around with Tera Blast more because I sincerely believe the move is still underutilized.
Speaking of TB, the next mon I want to highlight is something I have been harping on for awhile: Roaring Moon.

Roaring Moon @ Booster Energy
Ability: Protosynthesis
Tera Type: Fairy
EVs: 252 Atk / 4 Def / 252 Spe
Adamant Nature
- Scale Shot
- Knock Off
- Tera Blast
- Dragon Dance
The main thing here is Tera Fairy. Dark/Fairy is one of those magic type combinations that is very tough for an opponent to deal with defensively. In addition to that, Fairy is a great defensive typing. So you get offense and defense. This gives you a great alternative to the Tera Flying sets that everyone with no creativity spams everywhere. The lack of needing EQ to balance out Acrobatics means you can fit on Grassy Terrain easier. Anyways, I have Scale Shot here because it is a decent Dragon move that allows you to get to +2 with only one DD as setup. Or even +1 speed with BE attack and no setup when it suits you. It's maybe not the most necessary tech on webs, but it's still more than fine for most teams. I think Taunt could maybe be better on this team, though I haven't tested that yet. Either way, I find Scale Shot to be a lot more fresh of an idea.
This replay can show this mon setting up in Lando-T's face:

That speaks for itself. It's not exactly high ladder, but I don't think anyone can say this wouldn't translate to high ladder. RM does what it does well. I highly encourage people to try more set diversity than just Tera Flying Acrobatics. The sooner people realize that this thing isn't just a set or two, the sooner they will realize just what a monster it has always been.
