2 booster boxes 1e edition Engels Duelist Nexus is a Yu-Gi-Oh! TCG booster set introducing the new "Illusion" monster type (which can't be defeated in battle but disrupts opponents) and powerful support for Synchro strategies, featuring cards from Yu-Gi-Oh! 5D's like the Crimson Dragon, plus new Infernoble Knights and Dinosaur support, plus it's the first set with Quarter Century Secret Rares. Key Features: Illusion Monsters: The first new monster type since Cyberse, focused on unique battle-avoidance and disruptive effects (e.g., Nightmare Magician). Synchro Support: Fast-paced cards inspired by Yu-Gi-Oh! 5D's, bringing the powerful Crimson Dragon into play. Infernoble Knights: Continues the story of these fiery knights with new Link and support cards. Dinosaur Support: New Grenosaurus and Evolsauri cards for evolutions. Quarter Century Secret Rares: Special rare versions of 25 cards to celebrate 25 years of the game. In essence, it's a core booster set focusing on speed, new monster mechanics (Illusion), and nostalgic support for 5D's fans, offering a mix of new strategies and powerful additions to existing archetypes.
