Yu-Gi-Oh! Loonatics

'''Yu-Gi-Oh! Loonatics''' is a mix of Loonatics Unleashed and the Yu-Gi-Oh! series.

Plot
After the world is saved from evil, the Loonatics (now guardians of the galaxy) return to Earth to discover a game created from Egyptian times and receive their own decks that are inspired by the famous legendary duelists before them. Now, Ace, Lexi, Danger, Tech, Rev, and Slam must duel with all their powers to protect the world from new and old enemies, with their new duel monster pals, spell cards, and trap cards that will make them not just the legendary duelists of the world, but also the legendary duelists of the galaxy!
