Yusei has just [[Limit Over Accel Synchro Summon]]ed "[[Shooting Quasar Dragon]]". Yusei explains that its first effect allows it to attack once for each [[Synchro Monster]] used for its Synchro Summon. Since Yusei used five Synchro Monsters, "Shooting Quasar Dragon" can attack 5 five times. Yusei also explains "Quasar's" the second, third, and fourth effectsof "Shooting Quasar Dragon": When it attacks, it can negate an effect that negates until the end of the Battle Phase; it prevents all effect damage to Yusei; and it is unaffected by his opponent's monster effects.

"Shooting Quasar Dragon" attacks "[[Michion, the Timelord]]". The third effect of "Michion" activates, which would inflict damage to Yusei equal to half of his [[Life Points]], but "Shooting Quasar Dragon's" third effect prevents all effect damage. The first effect of "Michion" would negate its destruction by battle, but the second effect of "Shooting Quasar'sDragon" second effect negates that effect. "Michion" is destroyed, but its second effect reduces the battle damage that Z-one would have taken to 0.

"Shooting Quasar Dragon" attacks "[[Hailon, the Timelord]]". The third effect of "Hailon" activates, which would inflict damage to Yusei equal to the difference between his and Z-one's [[Life Points]] (currently 2000), but "Shooting Quasar Dragon's" third effect prevents all effect damage. The first effect of "Hailon" would negate its destruction by battle, but the second effect of "Shooting Quasar'sDragon" second effect negates that effect. "Hailon" is destroyed, but its second effect reduces the battle damage that Z-one would have taken to 0.

"Shooting Quasar Dragon" attacks "[[Raphion, the Timelord]]". The third effect of "Raphion" activates, which would return "Shooting Quasar Dragon" back to Yusei's Extra Deck and inflict damage to Yusei equal to "Shooting Quasar Dragon's" ATK (4000), but "Shooting Quasar Dragon's" third effect prevents all effect damage and its fourth effect makes it immune to "Raphion's" effects. The first effect of "Raphion" would negate its destruction by battle, but the second effect of "Shooting Quasar'sDragon" second effect negates that effect. "Raphion" is destroyed, but its second effect reduces the battle damage that Z-one would have taken to 0.

"Shooting Quasar Dragon" attacks "[[Gabrion, the Timelord]]". The third effect of "Gabrion" activates, which would return all cards Yusei controls to his Deck, but "Shooting Quasar Dragon's" fourth effect makes it immune to "Gabrion's" effects (and Yusei controls no cards other than "Shooting QuasarDragon" to be returned). The first effect of "Gabrion" would negate its destruction by battle, but the second effect of "Shooting Quasar'sDragon" second effect negates that effect. "Gabrion" is destroyed, but its second effect reduces the battle damage that Z-one would have taken to 0.

Finally, "Shooting Quasar Dragon" attacks "[[Sandaion, the Timelord]]". The third effect of "Sandaion" activates, which would inflict 4000 damage to Yusei, but "Shooting Quasar Dragon's" third effect prevents all effect damage. The first effect of "Sandaion" would negate its destruction by battle, but the second effect of "Shooting Quasar'sDragon" second effect negates that effect. "Shooting Quasar Dragon" and "Sandaion" destroy each other in a [[Double KO]].

Since "Shooting Quasar Dragon" was removed from the field, its final effect activates, destroying all monsters on the field (there are none) and Special Summoning "[[{{Monster|Shooting Star Dragon]]" }} from Yusei's Extra Deck (3300/2500) in Attack Position with its effects negated. "Shooting Star Dragon" attacks Z-one directly (Z-one 4000 → 700). Yusei activates the effect of "[[Speed World 2]]", removing 7 to remove seven [[Speed Counter]]s to and draw 1 a card (Yusei's [[Speed Counter|SPC]]: 7 → 0). Yusei Sets 1 a card.

(Z-one's SPC: 8; Yusei's SPC: 1)<br />Z-one draws "Sephylon the Ultimate Timelord". He then activates During the Standby Phase, the final effect of "[[Infinite LightSpeed World 2]]" as activates (Z-one's SPC: 7 → 8; Yusei's SPC: 0 → 1). As 10 or more "Timelords" with different names have been Summoned so far during this Duel, allowing him Z-one activates the final effect of "[[Infinite Light]]" to send it to the [[Graveyard]] in order to and [[Special Summon]] "[[{{Monster|Sephylon, the Ultimate Timelord]]" from his [[hand]] (4000/4000) }} in Attack Position. Z-one then activates the first effect of "Sephylon, the Ultimate Timelord" to Special Summon "[[Metaion, the Timelord]]" (0/0), "[[Sadion, the Timelord]]" (0/0), "[[Gabrion, the Timelord]]" (0/0), and "[[{{Monster|Sandaion, the Timelord]]" (4000/4000) }} from his Deck and Graveyard in Attack Position and give all four Special Summoned monsters 4000 ATK ("{{Monster|Metaion": 0 → , the Timelord|atk=ATK+4000/0; "}}, {{Monster|Sadion": 0 → , the Timelord|atk=ATK+4000/0; "}}, {{Monster|Gabrion": 0 → , the Timelord|atk=ATK+4000/0}}). Due to the second effect of "Sephylon", it gains ATK equal to the total ATK of all other "Timelord" monsters on the field ("Sephylon": 4000 → 20000/4000).

"Sephylon" attacks and destroys "Shooting Star Dragon". The (Due to the third effect of "Sephylon" , it negates the effect of any monster it battles with, so Yusei cannot use the effect of "Shooting Star Dragon" to negate the attack). Yusei activates his Set face-down "[[Converging Wishes]]", whose first effect negates to negate the Battle Damage he would take. Its Yusei then activates the second effect allows Yusei of "Converging Wishes" to [[Synchro Summon]] "[[{{Monster|Stardust Dragon]]" (2500/2000) }} in Attack Position by removing from play "[[Power Tool Dragon]]" and "[[Turbo Synchron]]" in his Graveyard. Due to the third effect of "Converging Wishes", "Stardust Dragon" gains ATK equal to the total ATK of all [[Dragon]]-[[Type]] Synchro Monsters in Yusei's Graveyard ("Stardust Dragon": 2500 → 23000/2000).

Yusei then activates the final effect of "Converging Wishes", allowing him to return a Synchro Monster in his Graveyard back to the [[Extra Deck]] in order to force an opponent's monster to attack. Yusei returns "[[Ancient Fairy Dragon]]" to his Extra Deck ("Stardust Dragon": 23000 → 20900/2000) to force "Sephylon" to attack; since Yusei controls only "Stardust Dragon", "Sephylon" must attack it. Z-one activates the fourth effect of "Sephylon", removing from play "[[Metaion, the Timelord]]" in order to prevent "Sephylon's" destruction and reduce the Battle Damage he would take to 0 ("Sephylon": 20000 → 16000/4000).
