Contact Fusion

You do not use "Polymerization".

Contact Fusion (コンタクト融 (ゆう) 合 (ごう) Kontakuto Yūgō) is a semi-official term which means to Special Summon a Fusion Monster with its own Summoning procedure, instead of requiring "Polymerization" or card effects.^[1]

General rules

• Contact Fusion is not a Fusion Summon, and instead is a built-in Special Summon (like Synchro Summon, Xyz Summon and Link Summon).
  • Attempting to Special Summon via Contact Fusion opens the Summon negation window and does not start a Chain.
  • Fusion Substitute Monsters cannot be used for Contact Fusion.

• All Fusion Materials involved in the Special Summon must be on the player's field, unless stated otherwise as per card effects.
  • The Fusion Materials used are then removed from the field via either banishing them, returning them to the Deck, sending them to the Graveyard, or Tributing them.

• If using a face-down monster as a Fusion Material for a Contact Fusion that returns it to the Deck, the player conducting the Summon must reveal that monster before shuffling it into the Deck to allow your opponent to verify the card's identity.
  • This is redundant for Contact Fusions conducted via banishing, sending to the Graveyard, or Tributing, as their Fusion Materials can be publicly verified afterwards.

• Much like all Extra Deck monsters, most Fusion Monsters that use Contact Fusion can be Special Summoned from the Graveyard or while Banished, as long as they were successfully Special Summoned from the Extra Deck via Contact Fusion first.
  • Like all Extra Deck monsters, this does not apply if the monster is returned to the Extra Deck; in that case, the monster must be Special Summoned via Contact Fusion again.

History, Anime and Manga

The first instances of this Summon were in the original Yu-Gi-Oh! manga, where specific monsters could be fused into a Fusion Monster without the use of "Polymerization". The first monster that was Summoned in this manner was "Valkyrion the Magna Warrior". Unlike Fusion by "Polymerization", monsters created by this method could attack in the same turn they were created.

This term was first widely introduced in Power of the Duelist, and was originally a term from the Yu-Gi-Oh! GX anime used to describe the Special Summoning method of the "Neos" Fusion Monsters, which are Summoned by shuffling their Fusion Material Monsters from the field into the Deck. This term was later applied to the "Gladiator Beast" Fusion Monsters by players, as those monsters Special Summon themselves via the same method.

The term has never appeared in the rulebook or any card effect text, but it does appear in the flavor text of "Elemental HERO Neos" and is often used in rulings.

This Special Summon can be considered to be a precursor to Synchro Summoning, Xyz Summoning, and Link Summoning, as it only requires the proper monsters on the field and the appropriate monster in the Extra Deck, without the need of a Spell Card (as used in most Ritual Summons and Fusion Summons).
