Here is smogon page about Fling | SS | Smogon Strategy PokedexHow does Fling actually work? If I fling for example, a Leftovers Lando-T a Ring Target, will the effects of the ring target remain? Or would Lando have to be itemless, so the immunity negating effect can last? Or does it not get the effect at any point?
Since the mon has to be holding Ring Target to suffer its effects, it only does nothing but damage when flung.
