Yūya Sakaki vs. Noboru Gongenzaka
At the start of the Duel, the Field Magic Card "Sword's Graveyard" is activated, as per the rules of an Action Duel. It will allow the players to use Action Cards, but they may only have one in their hand at a time.

Turn 1: Gongenzaka

Gongenzaka Normal Summons "Superheavy Samurai Kageboshi" (CG Star 3/500/1000). As it was Normal Summoned this turn, he activates its effect, letting him Release it to Special Summon a "Superheavy Samurai" monster from his hand. He Releases it to Special Summon "Superheavy Samurai Big Benkei" (CG Star 8/1000/3500) in Defense Position.

Turn 2: Yūya

Yūya draws and subsequently Normal Summons "Entermate Silver Claw" (CG Star 4/1800/700). He finds and activates the Action Card "Extreme Sword", increasing the ATK of a monster on the field by 1000 until the End Phase ("Silver Claw" 1800 → 2800). He then finds and activates the Action Card "Over Sword", which increases the ATK of a monster on the field by 500 for the Battle Phase only ("Silver Claw" 2800 → 3300), and prevents its attacks from being negated. "Silver Claw" attacks "Big Benkei", with its effect activating and increasing its ATK by 300 ("Silver Claw" 3300 → 3600) during damage calculation. Gongenzaka activates the effect of the "Superheavy Samurai Soul Fire Armor" in his hand, sending it to the Graveyard to target a Level 5 or higher Defense Position "Superheavy Samurai" monster he controls. It cannot be destroyed by battle this turn, but its DEF is decreased by 800 ("Big Benkei" 3500 → 2700). Yūya Sets a card.

Turn 3: Gongenzaka

Gongenzaka draws and subsequently Normal Summons "Superheavy Samurai Horagai" (CG Star 2/300/600). He then tunes the Level 2 Tuner monster "Horagai" with the Level 8 "Big Benkei" to Synchro Summon "Superheavy Koujin Susano-O" (CG Star 10/2400/3800) in Defense Position.
