Ok This is my list of things that are most broken to least broken
1)

- This is the most broken by far, having a lot of set variety and just being able to nuke everything with CB, specs, use smth like sub to take advantage of switches is nuts. It has ok speed meaning it doesnt get outran by defensive pokemon and solid sp. def bulk allowing it to tank hits from special attackers and even super effective attacks
2)

- Booster energy, CB, and bulkier DD varients are ones that i picture are gonna be the best, after a booster energy boost the only things that can beat it are CB scizor (hope no tera steel/fire/water to beat CB BP), Tera fairy or water skeledirge (prob the one hard counter but it needs tera late game), mach punch breloom (gets owned by tera), quagsire (loses to taunt or CB)
So yeah the checks are shaky even then... and roaring moon can setup easily with 105/71/101 bulk esp since it can usually get one off by forcing smth out
3)

- Weakest out of the 3 and if you ban trick room setter hoopa-u then it has a ok shot at staying. It has bulk, power, and it has a ok typing so what is the catch? donphan, iron treads, and cyclizar is getting overwhelmed spinning and that means ur running often times 2 ground types which also which worsen ur MU into loom, quav, basculegion, gyara, etc.
"just switch it in" ok list me a mon that is good that it can switch in on, get a kill, and do smth else? even if it gets a switch in vs smth like gastro. alr cool, u do get to click a button and do a chunk of damage or you can eat a tera ghost surf/ ice beam which is pretty painful, tinkaton gigaton hammer is gonna hurt a decent amount
0 Atk Mold Breaker Tinkaton Gigaton Hammer vs. 252 HP / 0 Def Ursaluna: 130-154 (28 - 33.1%) -- guaranteed 3HKO after Stealth Rock and burn damage
Oooh that is alr like 40% chip dont forget the next time ur coming in ur gonna be below 50% and everyone who has played OU knows how hard it is to get value out of a mon with no priority, an ok typing, and being slow asf.
Bulk up is prob the set to go and I will test it out, flame orb is overated asf and a noob trap at the moment
