I'm giving a shiny Flittle to my friend when they get the chance to start their game and was just trying to make it a good one for them. I've already changed the ability and nature so I thought I'd look into changing its tera type to something good. Any Ideas?
I think fighting or just psychic because fighting is supereffective on steel and dark types that could resist/be immune to its stab attack/s. Bug is also viable, as it is supereffective on dark and psychic and turns all of its original weaknesses into resistances. However, it gives it weaknesses to rock fire and flying.
