I'm running a mono flying team, and I didn't think I'd have trouble with a psychic team but this field is super strong.
The main issues are I have no fake out to stop the trick room, and can't get a flying fakeout user at this point, and I also can't get stomping tantrum to destroy the field.
My current team is all lv. 59 -
Charizard - Flamethrower, Flame Burst, Dragon Rage, Strength
Swoobat - Psychic, Assurance, Air Slash, Calm Mind
Emolga - Acrobatics, Discharge, Volt Switch, Light Screen
Mantine - Wide Guard, Hydro Pump, Air Slash, Agility
Yanmega - Air S
