Eria, Blight Sorceress

When Elanor enters the battlefield, you lose the game unless you pay {3}{b}{p/b}.
{0}: Cast an instant, sorcery, enchantment, or creature card from your graveyard, replacing its cost with: {p/b}{p/b}{p/b}.
If this creature blocks or becomes blocked, deal 6 damage divided among any number of creatures or players, but each creature or player can only receive up to 1 damage each, and you must target yourself as one of the targets.
