Persian (M) @ Silk Scarf / Life Orb
Ability: Technician
EVs: 4 HP / 252 Atk / 252 Spe
Jolly Nature / Adamant Nature
- Hypnosis / Taunt
- Fake Out
- Feint
- U-turn / Bite
This role is mostly supporter, the fast Hypnosis is a great gift but the accuracy is a problem. You can choose Taunt for stopping hazards setting Pokemon or annoyer Pokemon in general.
The combination of Fake Out and Feint let you play some mental games with your foe , if your opponent predict you will use Fake Out and use Protect and similar moves, the next turn you can U-turn and switch in a good counter, then send Persian again but this time use Feint in your foe that will think you will be use Fake Out again, then break his/her protect and attack.
Feint is a weak move but with Technician and STAB become a move with enough power to be decent, priority + 2 and the plus to able broken Protect and similar moves.
If you use a Technician Persian, don't remove Feint, it is the attack that differentiates Persian from similar Pokemon like Ambipom and Purugly that can run a similar set.
You also can use an Adamant Nature and boost the cat's power, and still be fast enough to outspeed speed base 95 Pokemon with a speed boosting nature, and with two priority move you can attack first even to Pokemon that outspeed Persian.
Persian is frail, some good teammates are Pokemon with Intimidate like Arcanine and Salamance. If Ghost-type Pokemon are a trouble for you, you can replace U-turn for Bite.

Ability: Unnerve
EVs: 4 HP / 252 Atk / 252 Spe
Jolly Nature
- Charm
- Fake Out
- Return / Shadow Claw
- Play Rough
This set take advantages from the two Fairy moves Persian can learn :
Z-Charm turn this little cougar in a physical wall reducing your opponent attack two stages and raising his defense 1 stage.
Twinke Tackle inflict massive damage to commons Dragon-types like Garchomp and also Fighting-type Pokemon that want to threat Persian.
Shadow Claw rounds his coverage against Ghost-types, is preferred over Night Slash for hitting Gardevoir, Tapu Lele and Mimikyu super effectively. You can also ditch the Ghost coverage and choice more power with a STAB Return.
Unnerve is the prefered ability , you can stop Gluttony Alolan Muk and other berry reliant Pokemon.
Limber is a option if you want keep that very good speed.
