1 Tuner + 1 or more non-Tuner LIGHT monsters 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.
Michael’s removal effect is strong because it banishes any card on the field. Making him useful even outside of Lightsworn decks.
Lightsworn decks mill their deck which provides quick setup and can trigger some of their effects. Michael’s second effect can prevent you from decking out due to Lightsworn’s playstyle while also healing you.
