Mechanics [ edit ]
A Fusion Summon can only be performed by a card effect. Effects that Fusion Summon first require the player to "use" appropriate monsters as Fusion Materials listed on a Fusion Monster by moving them from some location(s) to another, then after that Fusion Summon the Fusion Monster from the Extra Deck face-up to an unoccupied Main or Extra Monster Zone.
Most commonly, cards with effects that can Fusion Summon are Spell Cards (e.g. "Polymerization"). These effects typically involve using monsters from the player's hand or field as Fusion Materials. If not otherwise specified in the card text, monsters used as Fusion Material are sent to the Graveyard.
When an effect to Fusion Summon resolves, if the required Fusion Materials cannot be used or the Fusion Monster cannot be Fusion Summoned, no Fusion Summon occurs, nor are any Fusion Materials moved. For example, if the activating player cannot Special Summon when "Polymerization" resolves, no monsters are sent to the Graveyard as Fusion Material.
Even if all of a player's Monster Zones are occupied, a Fusion Monster can still be Fusion Summoned as long as at least one of the monsters in these zones is used as Fusion Material, so that there is an available zone when the Fusion Monster is Summoned. Otherwise, if there is no room to Fusion Summon a monster when a Fusion Summoning effect resolves, the Fusion Summon is not performed.
Face-down monsters on the field can be used as Fusion Materials, as long as they are controlled by the player performing the Fusion Summon and the card performing the Summon allows it. [1]
Fusion Summoning effect variations [ edit ]
As Fusion Summons are always performed by card effects, the specific actions involved in Fusion Summoning are exclusively determined by the individual effects that do so, meaning that their details can vary significantly.
- Cards of all card types can have Fusion Summoning effects. For example, "D/D Swirl Slime" (Monster Card), "Polymerization" (Spell Card), "Necro Fusion" (Trap Card).
- Fusion Summoning effects can use monsters from various locations as Fusion Materials, sometimes moving materials to different locations based on their original location. Examples:
- "Super Polymerization" (uses monsters from either player's field as material)
- "Miracle Fusion" (banishes monsters from the field or Graveyard as material)
- "Cyberdark Impact!" (shuffles monsters from the hand, field, or Graveyard into the Deck as material)
- "Parallel World Fusion" (shuffles banished monsters into the Deck as material)
- "Brilliant Fusion" (uses monsters in the Deck as material)
- "Odd-Eyes Fusion" (uses monsters in the Extra Deck as material)
- "Ghost Fusion" (uses monsters from the field as material, but can also banish a monster from the hand, Deck, or Graveyard as material)
- "Magistus Invocation" (can use Monster Cards treated as Equip Cards as material)
- "Pendulum Fusion" (can use Pendulum Monsters in the Pendulum Zones as material)
- "Vision Fusion" (can use Monster Cards treated as Continuous Traps as material)
- "Rapid Trigger" (Fusion Summons by destroying Fusion Materials)
- "Dark World Accession" (Fusion Summons by discarding Fusion Materials)
Interactions with effects [ edit ]
- Some cards have effects that allow the player to use monsters from locations other than the ones specified in the Fusion Summoning effect as materials when Fusion Summoning (e.g. "Cybernetic Fusion Support", "Chain Material").
- Fusion Substitute Monsters can be used in Fusion Summoning effects in place of a material with specified conditions that the Fusion Substitute Monsters inherently do not fulfill. Usually, they can substitute for a material with a specifically listed name, but "Shaddoll Core" can substitute for materials of certain Attributes instead.
- Some Fusion Monsters have a condition that they must be Fusion Summoned with their listed Fusion Materials, which prevents Fusion Substitute Monsters from substituting any of the Fusion Materials. However, this restriction only applies to Fusion Material substitution effects—it does not prevent using monsters whose names have been changed to or treated as a different card name from being used as a material according to that name.
Treating a Special Summon as a Fusion Summon [ edit ]
Main article: Treats Special Summon as Fusion Summon
Some card effects can Special Summon a Fusion Monster, treating that Special Summon as a Fusion Summon. This type of Special Summon is not a Fusion Summon despite being treated as one, so it does not necessarily follow any mechanics of a Fusion Summon.
