Featured Duel: Tai Kamiya vs. Kari Kamiya
 Turn 1: Tai 

Tai draws. He then Normal Summons "Shining Honor Knight" (1600/1400) in Attack Position. He then equips "Shining Honor Knight" with "Bravery Sword", increasing its ATK by 500 ("Shining Honor Knight": 1600 → 2100/1400). Now whenever "Shining Honor Knight" attacks or is attacked, it gains 300 ATK.

 Turn 2: Kari 

Kari draws. She then Normal Summons "Angel Archer" (1200/1100) in Attack Position. Since "Angel Archer" was Normal Summoned, its effect activates, allowing Kari to Special Summon "Twilight Tiger" (1400/0) in Attack Position. She then activates "Celestial Siege" to Tribute "Angel Archer" and "Twilight Tiger" and Special Summon "Ophanimon" (2700/2000) from her hand in Attack Position. "Ophanimon" attacks "Shining Honor Knight". The effect of "Bravery Sword" activates ("Shining Honor Knight": 2100 → 2400/1400). "Ophanimon" then destroys "Shining Honor Knight" (Tai 4000 → 3700). She then activates "Crystal Striker" to inflict 1000 damage to Tai and destroy all cards in Tai's hand (Tai 3700 → 2700).

The duel continues in the next episode.
