Jaden Yuki's Deck has evolved greatly within both the anime and manga versions of Yu-Gi-Oh! GX. His Deck mostly contains "Elemental Hero" monsters, and his strategies normally focus of Fusion Summoning his weaker monsters for stronger ones with various effects. In Season 2, he gains a card called "Elemental Hero Neos" (which becomes his signature card), a card of his own design. This card is known for Contact Fusions with the "Neo-Spacian" monsters. He reveals that this kind of Special Summoning can be used without a "Polymerization" card.
