I tried to make this Dusknoir Lv 99 with legit EVs and decent IVs with shadow sneak, thunder punch, will-o-wisp, and pain split. Held Item Leftovers. Happiness 255 (maybe the issue but i haven't checked). Nature Impish. Met Safari Zone, caught Safari Ball. In Box 13 slot 8.
It always comes up as a Bad Egg, is there something I'm missing?
This is the code it gave me.
