Lêbat Ravenkeeper

When Lebat Ravenkeeper dies, you may exile her instead. If you do, until end of turn you may play cards from your graveyard and any card that would go to your graveyard is exiled instead.
"Ravens sing forgotten songs, of things that haven't been.They mourn for all unrighted wrongs, both outside and in. Raga Vith's remembered, so he's never truly gone. So harken to the lonely, know what path you're on." Myth of the Ravens, final verse
