Azraeon, the Soul of War

Flying, Vigilance, Haste
Creatures can't be sacrificed.
Whenever a player casts a noncreature spell, if it isn't the first spell that player cast this turn, Azraeon, the Soul of War deals 5 damage to that player or target creature that player controls.
Young warriors want nothing more than to witness the flames of Azraeon. Their predecessors pray for nothing more than to forget.
