Since Ralts isn't a ghost type, Earthquake isn't my strongest attack anymore, strong move ye, but my Normal moves are like Frustration and even Return do alot more just fyi . Setting Up Misty Terrain is good because 1, it boosts Fairy moves hurting my Komala and hurting Tyrogue even more and 2 I have no way of stopping you from doing it. Bewear (heh) That I may be at low EN, I can still recover it by using the Command Chill and since you're using Misty Terrain as a main order you'd allow me to have a free action to Chill without suffering anything major.
Komala Frustration -> Chill -> Frutration
Komala Frustration -> Chill -> Frutration
