Invasion: Vengeance provides more support for this archetype's Fusion and Gemini Summoning strategies.
As only one of its effects can be used per turn, "The Black Stone of Legend" can alternate each turn between Special Summoning a "Red-Eyes" monster from the Main Deck, and returning itself to the hand and a "Red-Eyes" monster from the Graveyard to the Deck.
The Fusion version utilizes "Red-Eyes Fusion" to use Normal and Gemini Monsters as Fusion Materials from the hand, Deck, or field, but it cannot use Gemini monsters from the Deck, as they are not treated as Normal Monsters there. Afterward, the Fusion Materials can be revived using "Return of the Red-Eyes". While "Archfiend Black Skull Dragon" has powerful effects in preventing the opponent from using card effects during its battles and recycling "Red-Eyes" Normal Monsters after inflicting damage, it has very strict Summoning requirements, as it requires a "Red-Eyes" Normal monster and a Level 6 "Archfiend" Normal Monster, forcing the inclusion of "Summoned Skull", "Red-Eyes Archfiend of Lightning", or "Beast of Talwar" in the Deck. "Meteor Black Comet Dragon" is a more flexible alternative that can be Summoned with "Red-Eyes Fusion", as it only requires any Level 6 Dragon-Type monster in addition to a Level 7 "Red-Eyes" monster. "Red-Eyes Fusion" and "Return of the Red-Eyes" can be searched by "Red-Eyes Insight".
"Black Metal Dragon" can equip itself to a "Red-Eyes" monster for an ATK boost and can search for a "Red-Eyes" card when sent to the Graveyard. "The Black Stone of Legend" and "Black Metal Dragon" can be revived by the effect of "Kinka-byo".
"Red-Eyes Darkness Metal Dragon" benefits from this archetype's support cards and can Special Summon a Dragon-Type monster from the hand or Graveyard every turn, greatly improving field presence. While it can be Special Summoned by banishing another Dragon-Type monster, an easier way to do this is with "Paladin of Dark Dragon". "Dark Dragon Ritual" can banish itself from the Graveyard to search for a "Red-Eyes" Spell/Trap. "Catalyst Field" can Normal Summon the "Red-Eyes" Gemini monsters without Tributing, then the second Normal Summon granted can unlock their effects.
The "Hieratic" archetype has support for Dragon-type Normal Monsters, which can be used in combination with "Return of the Red-Eyes" and "Meteor Black Comet Dragon", which requires any Level 6 Dragon-Type Monster as Fusion Material.
