Fall of Elesh Norn

(You may cast a legendary sorcery only if you control a legendary creature or planeswalker.)
Fall of Elesh Norn deals 4 damage to target creature or planeswalker. If the permanent dealt damage this way was legendary, Fall of Elesh Norn deals 1 damage to each creature and planeswalker target player controls.
When Koth led the remaining Mirrans to kill Elesh Norn, hope for the rebirth of Mirrodin returned.
