Persian-Alola @ Focus Sash
Ability: Technician
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
Snarl
Parting Shot
Hidden Power [Flying]
Nasty Plot
This set is the sweeper variant, which is the most common. Snarl is for it's STAB, Hidden Power Ice is for coverage, Parting Shot is to cripple the opponent and pressures a switch, and also allows you to switch as well. Nasty Plot changes Persians normally mediocre special attack stats into a powerful threat.
I hope I helped!! :D
