Luna's Decks

Luna plays an Ancient Fairy Deck, consisting of folkloric creatures and enchantments, mostly in the form of Fairy, Plant and Beast-Type monsters. Several of them are based on the spirits that Luna befriended while at the Duel Monster universe, notably her Spirit Partner; "Kuribon", "Regulus", and her Signer Dragon; "Ancient Fairy Dragon". She carries many support cards that protects them from harm, including the field spell, Ancient Forest, which prevents any monster from switching to Defense Position and destroys them after they attack.

Season 1
Luna's First Season deck was based around mythological creatures and spiritual folklore. This Deck helped her in the Consolation game of the Fortune Cup.

Season 2
Luna's season 2 ground Deck had more Support Cards for her "Ancient Fairy Dragon" and "Regulus". This Deck helped her in school duels, and assisted in the defeat of Aporia and the fall of the Divine Temple.

Manga
Luna's Deck within the manga seems to consist of a mix of her Forest cards along with Leo's Morphtronic cards in order for her to successfully Summon their Duel Dragons.
