My take prediction or wish on Fortune Teller
I really expect the class to revolve around Tarot Cards
open shop and tell fortunes on people which gives them temporary both buffs/debuffs these are in forms of fortune +/- effect, like bonus or minus Exp Rate, Drop Rate, Weapon Damage, Crit Rate, Magic AMP, Accuracy, etc.
Also throw cards at enemies like Twisted Fate/Gambit.
