When you use this monster's second effect, you also get its first effect. So this monster enables you to perform a Special Summon of a Fusion Monster without "Polymerization", etc., and also acts as a "substitute" for one of the Fusion Material Monsters.
(1) You can substitute this card for any 1 Fusion Material Monster. The other Fusion Material Monster(s) must be the correct one(s). (2) By Tributing Fusion Material Monsters on the field, including this card, Special Summon 1 DARK Fusion Monster from your Fusion Deck.
Using the second effect of this monster does not "properly" Fusion Summon the Fusion Monster. So it cannot be revived from the Graveyard, etc. If you use "Polymerization" then you can revive the Fusion Monster from the Graveyard, even if you used this monster as a "substitute" Fusion Material Monster.
The (1) effect does not have any classification. It is not an Ignition, Trigger, Quick, or Continuous Effect.
To use the second effect of this monster, you must Tribute this monster plus the legal Fusion Material Monster (s) written on the Fusion Monster. For example, to Special Summon "B. Skull Dragon" you must Tribute "The Dark – Hex-Sealed Fusion" as well as either "Red-Eyes B. Dragon" or "Summoned Skull".
This effect does not target.
This monster's second effect cannot be used to Special Summon Fusion Monsters that can only be Summoned by Fusion Summon, such as "Dark Paladin".
Using The Dark – Hex-Sealed Fusion as a Fusion Material does not start a Chain Link.
This effect does not apply if The Dark – Hex-Sealed Fusion is in the Deck / removed from play.
This card cannot be sent to the GY to when Special Summoning Chimeratech Fortress Dragon or XYZ-Dragon Cannon.
If The Dark – Hex-Sealed Fusion is named by Prohibition, you cannot use its effect.
The (2) Ignition Effect activates & resolves on the field.
Tributing this card and the legal Fusion Material Monster(s) on the field is a cost.
This effect does not perform a Fusion Summon, so it can activate while Non-Fusion Area applies, but it cannot Special Summon "Dark Paladin".
The Fusion Monster Summoned by this effect cannot be Special Summoned from the GY / removed from play, since it was not properly Fusion Summoned.
