Information is an extremely important aspect of this competitive game of dueling.
Even though there are many times when, even if you know what your opponent's deck is or what cards they have in their hand, you still end up in situations like "Sky Striker loses to healthy Tearlaments," this doesn't mean that information is meaningless.
If a Duelist knows what cards their opponent's deck contains and the type of cards they have prior to the duel, preparing counter cards in advance, even if it doesn't guarantee a win, can still make the opponent break into a cold sweat—like preparing Holy Spear and Sanaphond the Sky Prison if you know your opponent has an Infernoid deck; or preparing a few shots of Thunder Strike if you know your opponent has a Hero Deck.
These cards may not guarantee victory, but they can certainly make your opponent sweat.
Judai looked at the cards in his hand. Through his memory of The Supreme King's impression of Yubel and Tenjo Hikari's tutoring, he's not unfamiliar with Yubel.
He came here to duel with Yubel, not to "atone for sins," but to make Yubel understand that "pain" is not love.
Just as he promised Tenjo Hikari, he will not let his relatives and friends endure the cost and pain of "losing Yuki Judai."
Therefore, before the duel, he made up for everything he needed to know.
"Phantom of Yubel has the effect of releasing itself when the opponent's monster activates. It changes the effect to [the opponent destroys one Yubel from their hand card, Deck, or field]."
Hearing Judai articulate the effect of his Phantom, Yubel's expression turned even darker.
Judai actually knows this effect!
How is this possible?
While she was in a panic, the duelists around her also exchanged looks, with quite a few taking a sharp breath, clearly startled by this effect.
Because this is not a simple effect.
Changing the effect...
This effect means it's not nullifying or interfering, but altering the opponent's monster effect, in other words, even monsters unaffected by other card effects will have their activation changed to "destroy Yubel."
One might say it's both domineering and self-destructive.
"Yubel's monsters can't be destroyed by battle, and battle damage they take becomes zero, but after the battle, the opponent receives that damage." Judai continued to explain Yubel's effect, making the surrounding friends squirm.
As he spoke, his eyes began to emit a golden glow, and his whole demeanor shifted from calm to domineering: "Not only that, while your Nightmare Pain is on the field, my monsters must attack Yubel, and I must bear the inflicted damage...
In other words, any monster I summon to attack your Yubel will take double the battle damage."
"Eesh..." Kenzan felt uncomfortable just listening to it, his deck didn't seem to handle such a scenario.
Marufuji Shou listened and also shook his head non-stop, thinking that his and his classmates' cards might not deal with this either.
What about big brother?
Can big brother's deck handle this?
Judai looked at the cards in his hand and calmly raised one: "Pay 1000 Life Points, activate the Spell Card, Cosmic Cyclone."
"What?"
"This card can be activated by paying 1000 Life Points, targeting one Spell·Trap Card on the field. That card is banished. I want to banish Nightmare Pain."
From the depths of the dark cosmos, a golden storm appeared from nowhere, sweeping over Yubel's field, instantly engulfing Pain, tearing space, and taking it away.
Yuki Judai, LP: 4000→3000.
"Yubel, I know, although you haven't used that effect, while Opening of the Spirit Gates exists on your field with a LV 10 monster, you can once per turn retrieve one Continuous Spell Card from the Graveyard to your hand.
If I simply destroyed Nightmare Pain, you would retrieve that card next turn and continue dueling with pain and torment, right?"
"This... you..." Yubel didn't know how to describe her feelings now.
Whether in the past or the present, in dealing with Judai, she was always the proactive one. To her, Judai's thoughts and ideas were always within her grasp, and she could "help" Judai achieve anything he wanted.
But now, she felt out of step!
"Yubel, when I wasn't aware, seeing me in sadness and pain, you secretly knocked those kids who made me unhappy unconscious. This excessive protection made me suffer even more as a child, but you thought that was protection.
At that time, I wasn't aware of your existence, so when my parents sent you out of this world, I just thought my card design was recognized by Kaiba Company.
In the Other Dimension, you must have endured a lot of inhuman suffering, right?
That was my fault, due to my ignorance, so there's no need to forcibly consider that suffering as love, there's no need to justify my actions, no need to... endlessly torment yourself with pain."
He extended his hand to Yubel: "I am willing to offer my true love, as long as you are willing to abandon this cycle of pain."
