Secrets of the Lighthouse

|Aria of Relentless Waters|??|????|Spell Card|Spell||Ritual|||This card is used to Ritual Summon "Ghost of the Lighthouse". You must also banish WATER and/or LIGHT monsters whose total Levels equal 8 or more from either player's Graveyard.|

|Ghost of the Lighthouse|??|????|Aqua/Ritual/Effect|Water|8||0|0|This card can only be Ritual Summoned with the Ritual Spell Card, “Aria of Relentless Waters”. This card cannot attack. If this card would be destroyed by a card effect, you can banish 1 LIGHT or WATER monster you control instead. Once per turn, you can Special Summon 1 WATER or LIGHT monster from either player’s Graveyard, but its effects are negated. If you do, increase this card’s ATK by the ATK of the Summoned monster. When a WATER or LIGHT monster you control is attacked, you can banish 1 WATER or LIGHT monster from your Graveyard to redirect the attack to this card.|

Interesting - I think I would personally just use it in a WATER deck though.
