I was just about to move all my pokémon to my pokebank and start my game over to work on my living national dex when a harrowing thought came to me. What about the unique hold items that come from special events?
Since hold items can't be transferred to pokebank, is there any way to get those items back (or again) if you're pulling those legendary Pokémon out of pokebank rather than from an official event? Namely, the two items that made me think of this were Marshadium Z and Pikashunium Z in the Sun and Moon games, but the concept applies to X and Y as well as ORAS.
