Mimikium Z
The page claims that the player picks up the Mimikium Z after defeating the Totem Mimikyu in the back room Grand Trial battle. But I don't ever remember seeing anything dropped by Totem Mimikyu after defeating it and don't even remember if you can walk around in the back room after defeating it. Since it disappears after the trial and the page claims it is in the back room, how else are you possibly supposed to get the Mimikium Z? Because I never once got a chance to get it.
