Once per turn: You can pay 1000 LP, then target 1 card on the field; banish that target. When this card is destroyed: You can target any number of other "Lightsworn" monsters in your Graveyard; shuffle them into the Deck, and if you do, you gain 300 LP for each returned card. Once per turn, during your End Phase: Send the top 3 cards of your Deck to the Graveyard.
