=== Spellcaster ===At first, Romin pretended to not own a [[Main Deck|Deck]] of her own, but still acquired "[[Prima Guitarna the Shining Superstar (anime)|Prima Guitarna the Shining Superstar]]" from [[Princess G]] and kept the card as a good-luck charm. For her first [[Yu-Gi-Oh! Rush Duel|Rush Duel]], she used [[Yuga Ohdo|Yuga]]'s spare '''[[Spellcaster]] Deck''', adding "Prima Guitarna" to it and focusing on Summoning [[Summon]]ing it as quickly as possible to empower her [[Monster Card|monstersmonster]]s.

=== Psychic ===

After betraying [[Yuga Ohdo|Yuga]] and her [[Lucidien Kallister|other]] [[Gavin Sogetsu|friends]], Romin revealed her true '''[[Psychic Musician]] [[Main Deck|Deck]]'''. Her [[Deck]] puts an emphasis on managing her own [[LP]], [[pay]]ing LP to generate advantage, such as [[destroy]]ing cards or increasing [[ATK]], and using cards that increase LP to mitigate the [[cost]]. Her [[Signature card|ace monster]] is "[[Prima Guitarna the Shining Superstar (anime)|Prima Guitarna the Shining Superstar]]", which can increase the [[ATK]] of all monsters she [[control]]s by the number of her [[Monster Card|monsters]] her opponent [[controlmonster]]s by paying 1000 LP, which also enables this strategy. After her [[Duel ]] with [[Gavin Sogetsu]], Romin added "[[Powerful Pierce!! (anime)|Powerful Pierce!!]]" to her Deck to use in combination with her [[ATK]]-manipulation [[card effect|effects]]s. She also makes use of cards to [[send]] cards from her Deck to the [[Graveyard]], which she can retrieve with "[[Romanpick (anime)|Romanpick]]".

=== JAM ===After [[Gwendoline Purdy|Princess G]] gave Romin "[[CAN:D (anime)|CAN:D]]", Romin incorporates it into her [[Main Deck|Deck]] and introduced several cards that work in tandem with "CAN:D" and her low stats, such as "[[JAM:P Start! (anime)|JAM:P Start!]]", "[[JAM:P Up! (anime)|JAM:P Up!]]" and "[[Psychic Raid]]", as well as a new [[Signature card|ace monster ]] in "[[CAN - Re:D (anime)|CAN - Re:D]]", which can [[return]] "[[Romanpick (anime)|Romanpick]]" to Romin's [[hand]] and allow her to use its [[effect]] again, or as fodder for the effect of "[[Endoll (anime)|Endoll]]". She dubs this strategy "'''[[JAM]]'''". During the second season, Romin adds "[[Fusion (anime Rush Duel)|Fusion]]" to her Deck, allowing her to [[Fusion Summon]] the [[Omega Psychic]] [[Type]] "[[CAN:D LIVE (anime)|CAN:D LIVE]]" and "[[Princess Omega the Shining Megastar (anime)|Princess Omega the Shining Megastar]]".
