The world of Yu‑Gi‑Oh! features many iconic characters. Some are tied to legendary cards, others famous for their duel antics—but Seto Kaiba is unique: he combines both.
It's common knowledge that Kaiba's strategy is brutally straightforward: raw power. Even starting with a modest Level-4 Vanilla monster, he'll drop a Vampire Lord (1900 ATK)—a big threat right from turn one. Then in his mind, everyone plays like he does.
He ignores all the times he got steamrolled by puny Level‑2 or Level‑3 monsters. Because in his world, big numbers equal dueling skills—and if that's the standard, then his go-to weapon is always:
The Virus Card
Specifically, Crush Card Virus—a staple tied directly to Kaiba's deck.
In the anime, activating it by sacrificing a Dark monster under 1000 ATK wipes out your opponent's entire deck… absurdly powerful. In the TCG, it's refined—but still clever.
The virus-based descendants like the one You Ming played follow the same logic: condition + mass destruction.
> "Monsters with 1500 DEF or lower..."
Keith eyed his field:
Cannon Soldier (DEF 1300)
Motor Minion (DEF 1200)
Of course, both were smothered in swirling black virus goo and instantly collapsed.
> "Cannon Soldier and Motor Minion are destroyed."
Keith recovered quickly:
> "Even so—when Motor Minion is destroyed, it leaves behind two Tokens!"
He shook off the shock:
> "Now, will I summon Motor Omega next? And then use the 7-Ka Spell to boost its ATK?"
At his question, the tension in the air thickened. Even the dim candlelight felt crushing. Keith sensed his hand exposed by the virus card and smirked.
> "But so what?"
He held up his sole card—his monster of hope.
At that moment, the two lone Motor Tokens sparked with overcharged energy.
> "Now, using both Tokens as Tributes, I summon my ace!"
Lightning arced through the hum of mechanical engines. A flash of red steel: a hulking robot with bladed arms appeared.
> "Motor Omega!"
This was Keith's ace from the manga's storyline (even though it only appeared briefly).
> Motor Omega (Level 8)
DARK / Machine
ATK: 2800 / DEF: 2000
A solid 2800 ATK—but now it faced a new rival.
> "Dark Blade of the Dark World also has 2800 ATK."
The two giants stood off—different designs, equal presence.
Keith broke the tension:
> "Your monster only has that ATK because it's equipped. My Machine is on another level!"
Zzzt.
Above Motor Omega, a slot-machine screen materialized. The first reel revealed:
> 7
> "Equip Spell—Seventh One."
> "This attaches to a Machine monster and gives it +700 ATK or DEF."
> Motor Omega ATK: 2800 → 3500
> "But that's not all."
Keith clenched his fist.
> "Engine Overload!"
Boom!
Electrical arcs plus grinding pistons. Thick black smoke roiled from Motor Omega, and its screen glowed blood-red.
> ATK: 3500 → 4500
> "4500 attack! That's the same as Kaiba's signature monster—this battle's over!"
The roar of machinery filled the air.
> "Battle phase! Motor Omega attacks Dark Blade! Overload Punishment—let's finish this!"
Even on the brink, Motor Omega surged forward, its spinning arm-blade aiming to obliterate the warrior.
> "I win…"
Clang!
But instead of the sound of crushing victory, there was an unexpected clang.
Dark Blade had blocked the attack with its axe.
> "Impossible. Motor Omega should have higher ATK!"
> "It did… until damage calculation."
Hum.
Amid the standoff, the golden accessory Dark Blade wore suddenly blinked.
A palpable pressure rose. Even the roar of engines seemed to quiet.
> "What is that...?"
> "It's the effect of Overturn Pendant."
You Ming explained, locking eyes with Keith, who had grown pale from shock.
> "When equipped to a lower-Level monster battling a higher-Level monster, its ATK only increases during damage calculation."
> "By how much?"
> "500 ATK per Level difference."
Keith's eyes widened.
> "Motor Omega is Level 8!"
> "Dark Blade is Level 4."
You Ming inhaled deeply.
> "That means Dark Blade's ATK increases by 2000."
> "So its final attack…?"
Keith was speechless, but the numbers made it clear:
> Dark Blade (ATK: 2800 → 4800)
Crack!
Metal split. Sparks flew. Motor Omega shattered in two.
