Fusion ($3 )
Introduction to Fusion
A player can Fusion Summon a Fusion Monster from the Extra Deck by activating a card or effect that performs a Fusion Summon. An example of a card that can perform a Fusion Summon is the Spell card, "Polymerization". When that effect resolves, the player uses appropriate Fusion Materials listed on a Fusion Monster by moving them from some location(s) to another location, as specified by the effect performing the Fusion Summon (usually sending them to the Graveyard or banishing them). After that, the player Summons the Fusion Monster from the Extra Deck to an unoccupied Main Monster Zone that a Link Monster points to or an Extra Monster Zone in face-up Attack or Defense Position.
