Crow draws. He then activates his face-down "[[Blackback]]", to Special Summon "[[Blackwing - Sirocco the Dawn]]" from his Graveyard (2000/900) in Attack Position. Next, Crow Special Summons "[[Blackwing - Gale the Whirlwind]]" from his hand (1300/400) in Attack Position via its own effect. Crow then activates the effect of "Gale the Whirlwind", halving to halve "Hook the Hidden Knight's ATK and DEF until the End Phase ("Hook the Hidden Knight": 1600 → 800/0 → 0).  "Gale the Whirlwind" then attacks "Hook the Hidden Knight", but Hermann activates the effect of "Hook the Hidden Knight", switching both battling monsters to Defense Position. The second effect of "Hook the Hidden Knight" then activates (Crow 2400 → 1600). The shadow hook tries to grab Crow's Duel Runner again, but he jumps to avoid it. "Sirocco the Dawn" then attacks "Hook the Hidden Knight", but Hermann activates the effect of "Dark the Hidden Knight", Tributing it to switch "Hook the Hidden Knight" into Attack Position. The effect of "Hook the Hidden Knight" then activates, switching both battling monsters to Defense Position. The second effect of "Hook the Hidden Knight" then activates (Crow 1600 → 800). The shadow hook again tries to grab Crow's wheel, but he activates the flight mode of [[Blackbird]] to avoid it. Since a "Blackwing" monster Crow controls had battled with one of Hermann's monsters and that monster is still face-up on the field at the end of the Damage Step, he Crow sends "[[Blackwing - Etesian of Two Swords]]" from his hand to the Graveyard to inflict damage to Hermann equal to the ATK of "Sirocco the Dawn" (Hermann 4000 → 2000).  Crow then activates his face-down "[[Urgent Tuning]]" to allow himself to Synchro Summon one Synchro Monster during the Battle Phase. Hermann activates [[Shadow Concealing Darkness]]. Now Defense Position monsters can't be destroyed in battle. If Crow has a LIGHT monster on his field, "Shadow Concealing Darkness" will be destroyed. Crow then tunes his two monsters together to Synchro Summon "[[Black-Winged Dragon]]" (2800/1600) in Defense Position. Crow then activates his face-down "[[Defenders Intersect]]", switching "Hook the Hidden Knight" and "Black-Winged Dragon" to Attack Position and negating both monsters' effects. "Black-Winged Dragon" attacks and destroys "Hook the Hidden Knight" (Hermann 2000 → 0). Due to the rulings of the WRGP, it goes immediately to Crow's End Phase. Hermann activates "[[Revival Knight]]" to Special Summon "Hook the Hidden Knight" (1600/0) in Defense Position, but Crow activates his face-down "[[Gravity Collapse]]", Tributing "Black-Winged Dragon" to negate the summon of "Hook the Hidden Knight" and destroy it.
