Inuyasha_Riku
the drumming duelist
i was planning on going to a tourney tomorrow using a deck with The Light - Hex-Sealed Fusion but im a bit confused about how it works...like can i just use its first effect(fusion sub) and Polymerization to fusion summon lets say Cyber Twin Dragon and NOT use the second effect(tribute it and a correct fusion material monster to special summon a light attribute fusion monster)? the second one is can i use either of its effects to special summon any of the XYZ fusions?
