If a porygon uses conversion 2 on struggle or curse what happens. Can it become ??? type? Does ??? type even have resistances? I'm guessing he'll just become normal.
Edit: I think curse would have to be used by a ghost type
Edit2: Assume curse is not being used in GEN V
When Conversion 2 is used after Curse, nothing will happen as Curse isn't an attacking move. If used against Struggle, nothing will happen either, because nothing can resist Struggle.
