Wish Upon the Ancient Demon

(You may cast a legendary sorcery only if you control a legendary creature or planeswalker.)

You may pay 6 life, exile six creature cards from your graveyard and sacrifice six permanents. If
you do, draw thirteen cards.
"People who cease to believe in God or goodness altogether still believe in the devil. Evil is always possible. And goodness is eternally difficult."
- Anne Rice
