In this game, Exarion Universe appears as one of the Theme Duel opponents; it challenges the player to defeat it after first inflicting 10,000 points of Battle damage to its LPs during the Duel.
True to this Theme Duel's objective, Exarion Universe uses a Deck titled "Healing Universe". Compared to the "Spirit Smile" Deck piloted by the Raging Flame Sprite Theme Duel opponent in the same game, who has a similar objective (albeit to inflict 20,000 points of Effect damage to its LPs during the Duel before defeating it,) this Deck has slightly less vigorous LP recovering effects as it is much easier to inflict damage to LPs by battle in this game (e.g. having "Mooyan Curry" in this Deck as opposed to "Dian Keto the Cure Master", which Sprite uses for an identical purpose.) Furthermore, this Deck also puts slight focus on ploys ranging from Beatdown, field-removal micromanaging and even battle damage prevention (as seen with the inclusions of cards like "Winged Kuriboh", "Collapse" and "Sakuretsu Armor".)
