In preparation for the Battle City Tournament, Yugi developed a new strategy using Magnet Warriors monsters that could combine to form one huge monster whose power could rival even Kaibas Blue-Eyes White Dragon! Structure Deck Yugi Muto refits the Magnet Warriors into new Electromagnet Warriors that attract each other from the hand, Deck, and Graveyard, and combine into the mighty Beserkion the Electromagna Warrior! Duelists can play these new cards on their own, but if they use them with the original Valkyrion the Magna Warrior they can Summon the new Imperion Magnum the Superconductive Battlebot, a 4000 ATK bruiser that can also negate your opponents Spell Card, Trap Card, or monster effect.

Each Structure Deck comes with a 40-card Main Deck and a 5-card Extra Deck for a total of 45 cards (40 Commons, 3 Super Rares, 2 Ultra Rares).
