Spirit of the Raging Flames

Vigilance, Trample
Whenever Spirit of the Raging Flames attacks,
exile the top card of each player's library. It
deals damage to each creature that you don't
control and each opponent equal to the total
converted mana cost of cards exiled with it this
turn. You lose that much life.
{t}: Choose target card in exile. You may cast that
card this turn and you may spend mana as though
it were mana of any type to cast it.
