I wanna talk a bit about Iron Thorns real quick bc I think he's quite slept on:

Iron Thorns @ Booster Energy
Ability: Quark Drive
Tera Type: Water
EVs: 56 HP / 252 Atk / 200 Spe
Jolly Nature
- Dragon Dance
- Stone Edge
- Earthquake
- Stealth Rock (this can be so much more! coverage out the ass, tera blast is nice too)
Water is just a generic defensive Tera that I used for the sake of resisting Jet Punch; other decent options ime include Flying (immune to EQs thrown at you, resist Mach Punch from Breloom which ime is a big danger for HO, neutral to a lot of other prio), Rock (haha stone edge go brr), Grass (good midground for resisting Jet Punch + Ground), but anyway I think this mon is really good on HO. You can say that about like all the paradox mons but shrug, I really wanna talk about how nuts this is though.
Nothing in SV OU really tanks these 2 moves at +2, p much everything that could got snapped; Toedscruel and Breloom are the only 2 mons that resist both and they both get wiped off the face of the earth:
+1 252 Atk Choice Band Tyranitar Stone Edge vs. 0 HP / 4 Def Breloom: 225-264 (86.2 - 101.1%) -- 12.5% chance to OHKO (+1 + booster energy, dies guaranteed if ur rock tera obv)
+1 252 Atk Choice Band Tyranitar Stone Edge vs. 252 HP / 96 Def Tentacruel: 233-274 (64 - 75.2%) -- guaranteed 2HKO after Black Sludge damage (idk if anyones running this mon or what spreads theyre running if so but ya not much chip required, dies if u rock tera, u wall it if grass tera, etc)
Its Speed tier is really nice, it's unfortunately slower than Chien-Pao even at +1 but these EVs let you outspeed Meowscarada at +1; you could go higher if Kilowattrel or Weavile end up being relevant but I don't see either happening (assuming Chien-Pao stays in the tier that is). Obviously after a DD you just kinda obliterate shit, like a lot of the mons ppl use to "check" this are just not answers at all lol, for example:
+1 252 Atk Choice Band Tyranitar Earthquake vs. 252 HP / 4 Def Iron Treads: 428-504 (111.4 - 131.2%) -- guaranteed OHKO
+1 252 Atk Choice Band Adaptability Tyranitar Stone Edge vs. 252 HP / 252+ Def Amoonguss: 452-532 (104.6 - 123.1%) -- guaranteed OHKO
+1 252 Atk Choice Band Adaptability Tyranitar Stone Edge vs. 252 HP / 168+ Def Corviknight: 374-442 (93.5 - 110.5%) -- 62.5% chance to OHKO
+1 252 Atk Choice Band Tyranitar Earthquake vs. 0 HP / 0 Def Garchomp: 261-308 (73.1 - 86.2%) -- guaranteed 2HKO after Leftovers recovery
It's not perfect obvs, you're walled pretty hard by Quagsire unless you're Ground Tera (or Grass Tera Blast) and stuff like Hippo can soft check, but being super bulky & having overall solid coverage against everything while being so strong with Booster Energy and compressing the SR slot for HO makes this mon worth looking into imo.
Here's the 5 min team I built with it; I played like 5 games so I'm sure there's a ton I'm missing, but it was fun to mess around with and I won em all (albeit on very low ladder).
