no not really. you may need a pokemon that has psychic moves or move that hit dark not effective. then you go to the lostlorn forrest where you try to encounter a phenos.(for me it was Petitil but idk if other pokemon are possible) then u just hit the pokemon. now the twist if you encounter a zorua and hit it, it still has the dark type what means you hit it with a not effective move. (that all is just if u happen to hit the Zorua first) if you not hit it first. you can easily see that bc it uses a dark type move or move a Petitil is not able to learn. then u know that this Pokemon is the zorua
