Rulings
- If a Sangan or a Witch of the Black Forest equipped with Horn of Light is Tributed and you activate the effect of Horn of Light, Horn of Light goes on top of your Deck and then Sangan or Witch of the Black Forest is resolved. If Sangan is destroyed (not Tributed) the effects of Sangan and Horn of Light are simultaneous and form a chain.
