Fire Lord Azula [Avatar: The Last Airbender]

Cost: 1 U B R Firebending 2 (Whenever this creature attacks, add R R. This mana lasts until end of combat.)
Whenever you cast a spell while Fire Lord Azula is attacking, copy that spell. You may choose new targets for the copy. (A copy of a permanent spell becomes a token.) I'm sorry it has to end this way, brother.
