Extinguishing Flame

(You may cast a legendary sorcery only if you control
a legendary creature or planeswalker.)
Continue (If you would lose the game this turn,
instead you exile your hand, graveyard and library,
and get an emblem with "You can't win the game".)
Extinguishing Flame deals 15 damage to any
target and 10 damage to you.
