Light Human J/resonators you control gain Precision and Barrier (Chant).

Enter or whenever this card attacks ⇒ If you control a J/ruler with "Lumia" in its name, target a resonator card in your graveyard. If the total cost of the chosen target is 2 or less, it doesn't share a name with this card, and it is a mono-attribute light resonator, a mono-attribute fire resonator or a dual attribute light/fire resonator, put it from your graveyard into the field.

Whenever this card leaves the field ⇒ Search your deck for a card named "Blessed Knight" and put it into the field, then shuffle your deck.
