Neo-Spacian

The Neo-Spacians were introduced by Jaden Yuki in the Yu-Gi-Oh GX anime. He created the concept of these cards when he was a little kid. The theme relies on Elemental Hero Neos and was designed to give Jaden an alternate strategy to his deck. Unlike most fusions that require a Fusion Summoning card, a new tactic known as Contact Fusion comes into play, which only needs to have the Fusion Materials on the field . However, monsters summoned through this effect are only allowed to be on the field until the End Phase of the turn of on which it was summoned. This can be bypassed through the Field Spell, Neo Space, which allows the Fusion Monsters to stay on the field as long as Neo Space itself stays on the field.
