yes i tried it once, have a pokemon platinum card and injected the flute item got a shiny Arceus from Hall of Origin leveled it to 100, then sent it to pokebank, later to HOME when the bank/HOME connection released and nothing happened.
i was little scared about the thing because many people was sending shiny locked mythicals and they got bad eggs, so later i decided to delete it, instead i sent my GTS Arceus from my old pokemon White card.
