The new World Premiere card coming with the Realm of Light Structure Deck later this month has finally been revealed!
Once per turn: You can send 1 “Lightsworn” monster from your hand to
the Graveyard, then target 1 other “Lightsworn” monster in your
Graveyard; add it to your hand. Each time a card(s) is sent from your
Deck to the Graveyard, place 1 Shine Counter on this card. If a
“Lightsworn” card(s) you control would be destroyed by a card effect,
you can remove 2 Shine Counters from your side of the field for each of
those “Lightsworn” card(s) instead.
Nice to know that it doesn't let you get back broken boss monsters like Judgment Dragon.
