[[Declan]] [[activate]]s {{Monster|D/D Magical Astronomer Galilei (later anime)|pendulum=right}} and {{Monster|D/D Magical Astronomer Kepler (later anime)|pendulum=left}} in his left and right [[Pendulum Zone]]s, respectively. He then [[Pendulum Summon]]s {{Monster|D/D/D Abyss Ragnarok the Complete Oblivion Overlord}} from his [[hand]] in [[Attack Position]]. Since it was [[Special Summon]]ed, he activates its [[card effect|effect]], which allows him to Special Summon a "[[D/D/D]]" monster from his [[Graveyard]]. He Special Summons {{Monster|D/D/D Wave Overlord Caesar|overlay=0}}, via this effect in Attack Position. Declan [[Normal Summon]]s {{Monster|D/D Necro Slime}}. He then activates the other effect of "Abyss Ragnarok", which allows him to [[Tribute]] 1 other "[[D/D]]" monster he [[control]]s and then [[banish]] a [[Monster Card|monster]] his opponent controls once per [[turn]]. Declan Tributes "Necro Slime" and banishes {{Monster|Rune-Eyes Pendulum Dragon}} via this effect. Declan activates the effect of the "Necro Slime" in his Graveyard. By banishing it from the Graveyard, he can [[Fusion Summon]] a "D/D/D" [[Fusion Monster]] from his [[Extra Deck]], using monsters from his side of the field as [[Fusion Material]]s. Declan fuses "Abyss Ragnarok" and "Caesar" to Fusion Summon {{Monster|D/D/D Caesar Ragnarok the Wave Complete Oblivion Overlord}} in Attack Position. Since "Caesar" was [[send|sent]] from the field to the Graveyard, he activates its effect, allowing him to [[add a card|add]] a "[[Covenant]]" card from his Deck to his hand. Declan adds "[[Re-contract Covenant]]" to his hand via this effect. "Caesar Ragnarok" [[attack]]s and [[destroy]]s {{Monster|Beast-Eyes Pendulum Dragon}} (Yuya: 2000 → 1800 LP). Declan [[Set]]s two cards.

[[Yuya Sakaki|Yuya]] Pendulum Summons {{Monster|Stargazer Magician}} and {{Monster|Odd-Eyes Pendulum Dragon}} from his Extra Deck in Attack Position. He then Normal Summons {{Monster|Performapal Pendulum Wizard}}. Yuya then activates the Pendulum effect of "[[Creation Magician (anime)|Creation Magician]]", changing the Level of "Stargazer" to that of another monster he controls. He targets "Pendulum Wizard" ("Stargazer": [[File:CG Star.svg|16px|link=Level]] 5 → 4). He then [[Xyz Material|overlays]] his two Level 4 monsters to [[Xyz Summon]] {{Monster|Dark Rebellion Xyz Dragon}} in Attack Position. He activates its effect, [[detach]]ing an [[Xyz Material|Overlay Unit]] to halve the [[ATK]] of a Level 5 or higher monster Declan controls ("Caesar Ragnarok" 3200 → 1600) and add that amount to its own ATK ("Dark Rebellion" 2500 → 4100) until the [[End Phase]]. Yuya activates the effect again, detaching another Overlay Unit to halve the ATK of "Caesar Ragnarok" again ("Caesar Ragnarok" 1600 → 800) and add that amount to its own ATK ("Dark Rebellion" 4100 → 4900). "Dark Rebellion" attacks "Caesar Ragnarok", but Declan activates its effect, allowing him to [[return]] one other card he controls to his hand and then [[equip]] a monster Yuya controls to it, with "Caesar Ragnarok" gaining ATK equal to the equipped monster's ATK. Declan returns "Kepler" to his hand and then equips "Odd-Eyes" to "Caesar Ragnarok" ("Caesar Ragnarok" 800 → 3300), with this effect. The attack of "Dark Rebellion" continues "Caesar Ragnarok" is destroyed (Declan: 1900 → 300 LP). Yuya Sets a card.

Declan [[draw a card|draws]] "[[D/D/D Hell Armageddon the Cruel End Overlord (later anime)|D/D/D Hell Armageddon the Cruel End Overlord]]". During the [[Standby Phase]], the Pendulum effect of "Galilei" activates, increasing its [[Pendulum Scale]] by 2 ("Galilei": [[File:Right Pendulum Scale.png|16px|link=Pendulum Scale]] 1 → 3). Declan activates {{Monster|D/D Magical Astronomer Kepler|pendulum=left}} in his right Pendulum Zones. Declan then Pendulum Summons {{Monster|D/D/D Abyss Ragnarok the Complete Oblivion Overlord|nolink=yes}} from his Extra Deck and {{Monster|D/D/D Hell Armageddon the Cruel End Overlord|nolink=yes}} from his hand in Attack Position. Since Yuya controls only one monster and no cards in his [[Spell & Trap Card Zone]]s, he activates his [[face-down]] "[[Misdirection Wing]]", which allows him to increase the ATK of a monster he controls by 800, and [[negate]] the effects of all cards Declan controls until the End Phase. Yuya targets "Dark Rebellion" for this effect ("Dark Rebellion" 2500 → 3300). Declan overlays his two Level 8 monsters to Xyz Summon {{Monster|D/D/D Kali Yuga the Twin Dawn Overlord}} in Attack Position. Since it was Special Summoned, its effect activates, negating the effects of all other face-up cards currently on the field except itself, until the end of the turn. Thus, the effect of "Misdirection Wing" is negated and the ATK of "Dark Rebellion" returns to normal ("Dark Rebellion" 3300 → 2500). "Kali Yuga" attacks and destroys "Dark Rebellion" (Yuya: 1800 → 800 LP).
