Moves
Hidden Power Fighting hits Alolan Sandslash, Aurorus, and Aggron harder than anything else, which can otherwise take advantage of Oricorio-E or even switch into it in the case of Alolan Sandslash. Taunt is an option that allows Oricorio-E to act as a stallbreaker, prevents Pokemon such as Clefairy and Audino from crippling it with Toxic, gives Oricorio-E more chances to set up, and shuts down entry hazards setters and removers like Mudsdale, Ferroseed, Qwilfish, and Skuntank. Finally, Revelation Dance is an alternative option for a weaker but more reliable STAB attack that also allows Oricorio-E to pressure Articuno and Regirock more easily.
Set Details
Dancer, albeit situational, allows Oricorio-E to punish moves such as Bellossom's Quiver Dance and Oricorio-G's Revelation Dance. Flyinium Z, when used alongside Hurricane, allows Oricorio-E to muscle past bulky titans like Audino, Mudsdale, Altaria, and even Pokemon that resist it like Lanturn. It also allows Oricorio-E to deal with frailer offensive threats, like Rotom-F and Skuntank, and ignore Hurricane's poor accuracy. Rocky Helmet is an alternative to Flyinium Z if you already have a Z-Move user on your team to chip down threats like Gurdurr, Primeape, Scyther, and Kangaskhan, which often use moves like Knock Off, U-turn, and Fake Out.
Usage Tips
Oricorio-E should take advantage of the Pokemon it checks and forces out to set up with Calm Mind, attack, or heal itself with Roost if it's weakened, which can also be used to reduce damage taken from Electric-type attacks from the likes of Lanturn and Eelektross. In order to prevent a momentum loss, it should wear down its checks such as Regirock and Alolan Sandslash before trying to set up with Calm Mind, although the latter struggles against Hidden Power Fighting variants. However, if the opponent only has checks unable to switch into Oricorio-E, such as Aggron, setting up with Calm Mind allows it to pressure the opposing team more easily. It's important to keep Oricorio-E away from status ailments, as they greatly cripple Oricorio-E and hinder its ability to check threats like Oricorio-G and clean with Calm Mind. Oricorio-E should be played differently depending on its last moveslot. Hidden Power Fighting hits Alolan Sandslash, Aurorus, and Aggron, which means that it can pressure them and even set up if they're the opponent's only check. However, if running Taunt, Oricorio-E can use defensive behemoths that could otherwise cripple it or set up alongside it like Altaria, Lanturn, and Clefairy as setup fodder.
Team Options
Oricorio-E greatly appreciates entry hazard removal, as it can be overwhelmed by threats like Gurdurr or forced to use Roost and lose momentum if Stealth Rock is present. Therefore, Rapid Spin and Defog users such as Alolan Sandslash, which checks Ice-types, and Skuntank, which chips Regirock, are heavily recommended. Lurantis is another good partner, as it can also pressure Regirock for Oricorio-E. Pokemon that appreciate Oricorio-E's ability to check threats like Gurdurr, Hitmonchan, Bellossom, and Oricorio-G work well alongside it. An example of this is Regirock, which can set Stealth Rock for Oricorio-E, cripple opposing Regirock with Toxic, and chip Alolan Sandslash. Oricorio-E also appreciates partners such as Substitute + Toxic Kangaskhan and Stoutland, which soften up walls like Regirock, Eelektross, and Lanturn for Oricorio-E; Stoutland can even Pursuit trap the latter two. Entry hazard setters like Aggron, Ferroseed, and Qwilfish make for decent partners to ease Oricorio-E's job; Qwilfish can also act as a secondary Fighting-type check, which reduces pressure on Oricorio-E. Oricorio-E often finds itself forced out by faster Rock-types like Lycanroc and Choice Scarf Kabutops. Due to this, it appreciates having a partner able to deal with them, such as Gurdurr, Mudsdale, and Tangela. In a similar vein, it also struggles against faster Ice-types such as Jynx and Choice Scarf Aurorus, which means that Pokemon able to switch into them such as Cryogonal and Lanturn or even Pokemon able to check them, like Choice Scarf Dodrio and Primeape, make for good partners.
