Sensu Form: Gen 9 NU Defog
Oricorio-Sensu @ Heavy-Duty Boots
Tera Type: Fighting
EVs: 64 HP / 252 Def / 192 Spe
IVs: 0 Atk
- Revelation Dance
- Hurricane / U-turn
A Defog set for Oricorio-Sensu. Defog allows Oricorio-Sensu to clear hazards from your side of the field. Defog is also nice for getting rid of the opposing team's screens should you face Screens HO. Revelation Dance is used for a Ghost STAB. Hurricane is for a Flying STAB that hits Passimian and Medicham super effectively. Hurricane is also nice vs opposing Oricorio so you can attack Oricorio without worrying about Dancer activating. U-turn can be used instead to switch out and generate momentum for the team. Roost is used to give Oricorio-Sensu a source of HP recovery.
Heavy-Duty-Boots is used to avoid getting chipped by Stealth Rock. 192 Speed EVs with a Timid Nature allows Oricorio-Sensu to outspeed base 85 Pokemon such as Toxicroak, Mabosstiff, and Qwilfish. 252 Defense EVs are used to help Oricorio take physical moves damage. The leftover EVs are used in HP. The Tera Type is Fighting to allow Oricorio-Sensu to throw Dark-type Pokemon off guard.
For those wondering why I have 252 EVs in Defense over HP, it's because investing in HP in this case is a little worse than using 252 EVs. Here are some calcs to prove it:
252 Atk Passimian Knock Off (97.5 BP) vs. 64 HP / 252 Def Oricorio-Sensu: 198-234 (64.4 - 76.2%) -- guaranteed 2HKO
252 Atk Passimian Knock Off (97.5 BP) vs. 252 HP / 64 Def Oricorio-Sensu: 246-290 (69.4 - 81.9%) -- guaranteed 2HKO
252 Atk Life Orb Pure Power Medicham Zen Headbutt vs. 64 HP / 252 Def Oricorio-Sensu: 207-243 (67.4 - 79.1%) -- guaranteed 2HKO
252 Atk Life Orb Pure Power Medicham Zen Headbutt vs. 252 HP / 64 Def Oricorio-Sensu: 255-302 (72 - 85.3%) -- guaranteed 2HKO
The EV spread with 252 Defense EVs take less damage than the set with 252 HP EVs. You can check for yourself with the damage calculator.
