Lack of STAB hurts, you know; Goodra is supposed to take advantage of bulk, not Speed.
Goodra @ Wide Lens
Nature: Jolly (+Spd, -SAtk)
Ability: Hydration
EV: 252 Atk, 252 Spd
Aqua Tail
Rock Slide
Rain Dance
Rest
Resists Fire Blast and Energy Ball, while high natural special defense will take the other two hits. Out-speeds and has two super-effective attacks with 100% accuracy thanks to Wide Lens.
Suicune @ Leftovers
Trait: Pressure
EVs: 252 HP / 252 Def / 4 SDef
Bold Nature (+Def, -Atk)
- Calm Mind
- Scald
- Rest
- Sleep Talk
Due to Choice Band, Rhyperior would be stuck to Stone Edge, which Suicune is bulky enough to endure. After it's sent out on the field, it would immediately use Scald and take down Rhyperior. If it's ever in low HP, it should always be able to recover itself with Rest. With Sleep Talk, it could continue attacking while it's asleep. :]
Rhyperior can actually take a Scald and 2HKO with Stone Edge, so Suicune can't really switch in.
Rotom-W @ Choice Scarf
Trait: Levitate
EVs: 4 HP / 252 SAtk / 252 Spd
Timid Nature (+Spd, -Atk)
- Volt Switch
- Hydro Pump
- Hidden Power [Ice]
- Trick
Staraptor @ Choice Band or Life Orb
Nature: Adamant
Ability: Intimidate
EVS: 252 Atk, 252 Spd, 4 HP
Moves: Brave Bird, Close Combat, U-Turn, (Idk the last move)
Staraptor would OHKO (i think) Ludicolo w/ Choice Band/Life Orb Brave Bird.
(Excuse me If I am incorrect I only really got into battling a few months ago...)
