This is a great card for Synchro Summoning. If you have a "Herald of Orange Light" on the field, you can Special Summon this card and tune for a level 8 Synchro. Then banish those materials to special summon another "Soul of Purity and Light" and Normal Summon another "Herald", Synchro Summon for another monster, and have two powerful level 8 Synchro Monsters on the field in one turn.
Use this card in conjunction with "Miraculous Descent". You'll be able to Special Summon "Soul of Purity and Light" from your hand, as well as another powerful Fairy-Type monster that you just banished from your Graveyard.
