RU is an absolute blast to play, lotta offensive options to try out but a decent chunk of defensive mons too so you don't have to just play: Who dies first? 
I wanted to just note a one of my favorite sets in the Meta right now:

Weavile @ Focus Sash
Ability: Pickpocket
Tera Type: Dark/Water
EVs: 252 Atk / 4 SpD / 252 Spe
Hasty Nature
IVs: 0 HP / 0 Def
- Swords Dance
- Beat Up
- Low Kick/Tera Blast
- Poison Jab
No surprises on the Mon, but the set may be a little unexpected. I think Bulky Physical Offense is the way to go in this tier right now. You've got a glut of options for setup sweepers, revenge killers, wall breakers, physical and special walls, hazard setters, and hazard removers. It's laughably easy to bring a well balanced squad of 6 mons with 110+ atk each, which turns Beat Up into a 100-110 BP move that doesn't miss and breaks sash. This thing actually just wins games on turn 1 if the opponent leads a hazard setter and doesn't have the right walls. But for the most part, it usually claims a mon, steals an item, and goes maybe 50/50 in forcing a terastalization. The beauty of going low kick over tera blast is of course that you save Tera for another mon down the line *cough Haxorus* who surely appreciates weavile forcing the physical walls in early and chipping them. Tera fire or Lum berry are other options to absorb wilo and get another dance but those are pretty niche.
Weavile @ Choice Band/Heavy-Duty Boots
Ability: Pressure
Tera Type: Water
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Tera Blast
- Beat Up
- Low Kick/Icicle Crash
- Poison Jab
Non-setup, Beat-Up weavile is a very nice mon to pressure opponents throughout the game. Super hard to switch into and blazing fast is unsurprisingly a great combination. Once again, it really appreciates the litany of mons with high base atk stats who keep hazards off your side, hazards on their side, and run through the holes that weavile cracks in the other team.
Here are some Beat-Up team options
Setup sweeper: Haxorus, Primeape, Honchkrow, Cloyster (not great atk but it's only 1.5 BP less than Primeape as far as beat-up goes)
Revenge killers: Heracross, Mabostiff, Krookodile, Passimian, Lycanroc-Dusk
Wall-breakers: Hariyama, Heracross, Copperajah (sneakily decent cuz it always lives 1), Ursaring
*be careful activating status orbs early cuz they will weaken Beat-Up
Physical walls: Mudsdale, Avalugg, Tauros-Paldea, Sandaconda, Arcanine
Special walls: Goodra, Arcanine, Hariyama, Primeape
Hazard setters: Mudsdale, Copperajah, Sandaconda, Heracross, Krookodile, Coalossal (again not great but as long as it's your only low atk it's fine)
Hazard removal: Braviary, Scyther, Avalugg, Coalossal, Altaria (see coal and cloyster)

One funny addition to Beat-Up teams is Sneasel who can force in and tera to beat the same mons that Weavile does, which then allows Weavile to act as a midgame breaker/cleaner. Its speed is freaking awesome letting it outrun Lycanroc and Espeon. Sneasel runs the first set on these teams while Weavile runs the second.

		 Massively overrated Altaria. It can't switch into the physical attackers at all, bar I guess Flamigo. Haxorus, Weavile, Murder Dog, they all destroy it. Now, if you want a physical wall to replace Altaria with and you've somehow left off the list entirely, let me introduce you to...

Ever since I faced it in OU once and it was weirdly difficult to deal with, I've been waiting for the tier where it can be great in, and RU appears to have the right power level for it. Makes amazing use of parabolic charge, especially when paired with its ability. You can use acid spray to lower spdf or soak to catch a ground type.

It's a hugely consistent game-to-game performer and can sometimes just win games by itself, very similar to its dad in OU. Believe the hype, the salt stack is good.

There's a couple of sets this thing can run. I've used the calm mind agility stored power set, and it can win games remarkably easy. It's ability preventing priority is amazing for an agility sweeper, and it has the bulk to get those boosts off reliably. Probably not in the A tiers, but definitely a lot higher than C-

Regenerator is just that good of an ability, and it has knock + rocks.

 Haxorus, much like Dragon Dance users in tiers above it, is a prime example of what can break Tera. Lose to Sableye and Slowbro? Tera Dark. Lose to Fairy- and Ice-types? Tera Steel. These are the two best examples but Haxorus has a very malleable movepool and bulk. Haxorus can also use Swords Dance with Trailblaze probably more effectively than Dragon Dance but that's up for debate.

Fantastic offensive presence even when defensively oriented, able to check a lot of the tier and reliably spread burns. Offensive sets are also quite good in their own right, with either Choice Band or Cud Chew strats. Intimidate and Fire-Fighting typing lets Tauros check big threats like Weavile, Slush Rush sweepers, and Heracross.

Particularly Choice Scarf sets are amazing offensively in a tier lacking good Steel-types while Trick and Trace give Gardevoir amazing utility.

I think the Shift Gear Tera-Normal set is quite overrated, but Choice Specs is nearly uncheckable and Shift Gear sets are still good, just not the auto-win button some people make it out to be.

  Insane Snow core, Cetitan is very difficult to check, especially with Tera. I've used Tera-Dark to wall Sableye but Tera Ice can make for even stronger +6 Ice Shards and Fairy, Fire, and Ghost can make for great defensive Teras to enable a safer Belly Drum.

 (Heat and Mow) The SSNU IronPress set that I made way back when is still super dumb. Basically the only good Steel-type with SR and good coverage too.

		 I am addicted to Knock Off, and Passimian is one of the few Pokémon that retain this move while also having a pivot option, good coverage and a good stab. Great mon, I think it's probably one of the top two fighting types right now, alongside Flamigo

RU actually favours this mon a lot, dangerous physical attackers suich as Haxorus exist in the tier rn and Avalugg is one of the only counters while also packing hazard control. I doubt this will stay long after Haxorus and other dangerous physical attackers leave but its certainly interesting how Tera has breathed life into this Pokémon.

This gen it got Stealth Rock and Spikes, topped with the fact that it has Oblivious to block Taunt from the likes of Froslass, so it definitely has a niche here.

Tera + Levitate is a great combo on any mon, give it to a strong special attacker with Nasty Plot and you have a recipe for success. My favourite set so far has been Tera Steel SubPlot Mismagius sets, using steels valuable resistances to get a plot up and ruin the opposing team. Cool Mon.

Lumping all three together because I think these 3 are all banworthy in the tier. Haxorus is crazy, when Avalugg is seeing usage to counter something, i think we have a problem. Toxtricity is a Tera Abuser with Boomburst + Punk Rock, absolutely shatters teams. You know something is strong when Blissey is 2HKO'd by it. Venomoth is probably the weakest of the 3 but still incredibly strong on screens teamstyles with Quiver Dance and also abuses Tera a lot, i prefer Tera Fire to hit Steels like Revaroom while also being able to hit Bronzong for Super Effective Damage. Overall, i hope when Beta comes that these 3 are looked at :)
