• This card can be Xyz Summoned by first using the effect of "D/D Swirl Slime" to use itself and a Level 8 "D/D/D" monster in your hand as Fusion Material to Fusion Summon a "D/D/D" Fusion Monster, then banishing "Swirl Slime" to Special Summon "Abyss Ragnarok" from your hand, and using its effect to Special Summon the Level 8 "D/D/D" monster from your Graveyard that was sent there with the effect of "Swirl Slime".
  • This card can easily be Xyz Summoned if there is a "D/D Savant Thomas" in your hand, "D/D Swirl Slime" in your Graveyard, and a "D/D" card in your Pendulum Zone. Use the effect of "Swirl Slime" to banish itself and Special Summon "Thomas". Then, use the effect of "Thomas" to destroy that "D/D" card in your Pendulum Zone and Special Summon a Level 8 "D/D/D" monster from your Deck. Overlay "Thomas" and the monster that was Special Summoned with its effect to Xyz Summon this card.
  • This card can more easily be Xyz Summoned by using the effect of "D/D Berfomet" on another "D/D" monster you control, changing its Level to 8. Then, another Level 8 "D/D" monster can simply be Summoned to fulfill this card's requirements.
  • Despite requiring specific Materials, "Xyz Universe" can also be used to Special Summon this card, making it usable in a great variety of Decks.
