Efreet Awakener

Whenever Efreet Awakener attacks, you
may have it deal 1 damage to you. If you do,
exile target card from your graveyard at
random. If it's an instant or sorcery card,
you may cast it until end of turn. If it's a
land card, add {r}{r}, and until end of turn,
you don't lose this mana as steps and phases
end.
