Realm of Light focuses on the Lightsworn Deck theme, which has been a very popular Deck for a number of years; reprints of Lightsworn cards have been the primary drivers for other products. Lightsworn Monsters are blessed with incredible effects, high ATK/DEF, or both; this Structure Deck comes with the most powerful of the Lightsworn forces.

Lightsworn have never had Extra Deck monsters before, but that all changes with the all-new Synchro Monster, Michael, the
Arch-Lightsworn, capable of banishing any enemy card while refilling your Deck and your Life Points! The Deck also includes 2 Lightsworn Tuner monsters! Finally, a vulnerability of Lightsworn Decks is finally redressed with Lightsworn Sanctuary, a world-premiere Spell Card!

The Realm of Light Structure Deck comes with a total of 41 cards:
- 2 Ultra Rares
