Fusion Summon

A Fusion Summon can be conducted by activating a Fusion Spell Card such as Polymerization, while the necessary Fusion Material Monsters are either in the hand or on the field. Fusion Material Monsters are sent from the hand or the field to the Graveyard and the Fusion Monster is Summoned from the Extra Deck. Certain cards allow you to fuse monsters in your Graveyard such as Miracle Fusion or Dark Calling.
