In the rare case where a legendary creature becomes a copy of another legendary creature with greater mana value (for example, if Sakashima the Impostor is a copy of a legendary creature with mana value 5 or greater), then when that creature dies, if it's still a legendary creature card in your graveyard, Havi's last ability will be able to target it
