Heroic Spirit Deck in Yu-Gi-Oh!-Chapter 415

Ruby valiantly sacrificed herself. After being struck by the energy of Elemental HERO Cosmo Neos, the only monsters remaining on Hoshino's field were Cú Chulainn Illya and Illya. Even the Continuous Spell Card Phantasm Summoning was destroyed.

"Now it's my turn..."

"Right at the start of your turn, Sensei, I activate my Set Trap Card: Fiend Comedian!"

[Fiend Comedian – Trap Card Effect: Toss a coin and call it. If you call it right, all your opponent's cards in the Graveyard are removed from play immediately. If you call it wrong, send a number of cards equal to the cards in your opponent's Graveyard from your Deck to your Graveyard.]

A spinning demonic coin launched from the revealed card, twirling in the center of the field.

"Sensei, your cards—even in the Graveyard—can still activate troublesome effects.

So this time, I'm going all in!"

Jaden narrowed his eyes as he watched the spinning coin. Even though it was a gamble, both outcomes worked in his favor—either banishing his opponent's entire Graveyard if he guessed correctly, or sending cards from his own Deck to the Graveyard if he guessed wrong. A win-win for his strategy.

"I've decided—Tails!"

Coin Toss Result: Tails

Luck was on Jaden's side. He guessed correctly. At that moment, all the cards in Hoshino's Graveyard were automatically ejected from her Duel Disk and moved to the banished zone.

"You seriously pulled something like this now?! Who taught you tactics like that?!"

"It was you, Sensei... Didn't you always say, 'All's fair in war and dueling' in your lectures?"

To think she'd been sabotaged by her own future self... With all her Graveyard resources gone at this crucial moment, Hoshino had no choice but to rely on the top-deck.

"My turn—Draw!"

Fortunately, the draw didn't disappoint. It wasn't amazing, but it wasn't bad either.

"I activate the Spell Card Polymerization from my hand!

Using the two Illyas on my field as Fusion Materials, I Fusion Summon—Heroic Spirit – Illyasviel von Einzbern!"

[Heroic Spirit – Illyasviel von Einzbern ★★★★★★ (Level 6) | LIGHT | Spellcaster/Fusion/Effect | ATK 1000/DEF 1000]

["Magical Girl – Illya" + 1 Effect Monster]

[This card is also treated as a "Magical Girl."]

Illya's elementary school uniform transformed into a magical girl's outfit. Her frilled pink lace skirt fluttered as she gently hovered onto the field.

"Illyasviel von Einzbern's effect—once per turn, if she has no Equip Cards: I can target one of my banished monsters and equip it to her. She gains ATK and DEF equal to the equipped monster's original stats."

The strongest monster currently in Hoshino's banished zone—though she hated to admit it—was...

"Oda Nobunaga!"

Inheriting Nobunaga's strength, Illya's magical attire transformed into countless blazing spears, saturating the dark sky above.

"Demon King of the Sixth Heaven!!"

[Illyasviel's ATK: 1000 → 4000]

"Go, Illyasviel! Fire the full volley of your Three Thousand Guns and shatter his Great Tornado!"

Bang—! Bang—! Bang—!

Flames tore through the raging wind. Accompanied by the blazing light of thousands of magical bullets, Elemental HERO Great Tornado on Jaden's field was consumed by the fierce barrage.

"This... is the Demon King's Three Line Formation!!"

[Elemental HERO Great Tornado – Destroyed]

[Jaden LP: 1400 → 200]

When the bombardment ended, only the smoke of gunpowder lingered on Jaden's side of the field. The tides had turned in a single turn—field and Life Points reversed in an instant. At this stage of the duel, even a single misstep could end everything.

"I end my turn!"

With no further plays after her attack, Hoshino decisively ended her turn.

[Hoshino: 1 Hand Card | 0 Set Card]

Yubel sighed with admiration. "So this is it, Jaden. To summon such a powerful monster even at the very end... Even if you lose, you won't have any regrets, right?"

"No, Yubel—I'm not giving up yet!" Jaden's heterochromatic eyes sparkled brighter. "There's still a chance. Lend me your power, Yubel!"

"I knew you'd say that~" Yubel smiled gently, already familiar with Jaden's refusal to surrender. "Then let's show her—the power we share... and the miracle of Super Polymerization!"

Drawing his final card, Jaden's Duel Spirit energy surged to its peak.

"This is my final trump card, Sensei! The power of heroes and heroic spirits converge at this moment—fates intertwined, transcending time and space to burn at their peak—Quick-Play Spell: Super Polymerization!"

[Super Polymerization – Quick-Play Spell: Discard 1 card; Fusion Summon 1 Fusion Monster from your Extra Deck, using monsters from either field as Fusion Material. Neither player can activate cards or effects in response to this card's activation.]

"I Normal Summon Elemental HERO Avian!

Then I discard Evil HERO Sinister Necrom from my hand to activate Super Polymerization!"

As Avian materialized on Jaden's field, an enormous surge of fusion energy erupted—pulling in even Hoshino's Illyasviel von Einzbern.

"I fuse my Avian with your Illyasviel!"

Hoshino's eyes widened. "A fusion between a HERO... and a Heroic Spirit?! Don't tell me—!"

Two intertwined destinies. On the day their paths crossed, Hoshino Chiyuki and Jaden Yuki each received a card that represented their hopes for the future.

"This is the card you entrusted to me when I first enrolled, Sensei! Now, I'll use it to claim victory!"

Jaden slammed a card from his Extra Deck onto his Duel Disk. From the storm of fusion energy, a new warrior was born—embodying both the spirit of a Hero and a Servant.

"Fusion Summon—Artificial Hero – Sieg!!"

[Artificial Hero – Sieg ★★★★★★ (Level 6) | LIGHT | Warrior/Fusion/Effect | ATK ?/DEF ?]

[1 "Heroic Spirit" monster + 1 "HERO" monster]

Staring at the familiar figure on Jaden's field, Hoshino murmured: "So it really is Sieg... Future me actually gave that card to you, huh."

"Sieg's effect activates! When this card is Fusion Summoned: Add 1 Polymerization Spell from your Deck to your hand."

Jaden grabbed the card Sieg searched. At the climax of this final duel, he didn't hesitate.

"The card I add is the Normal Spell that's turned countless duels in my favor—Miracle Fusion!"

[Miracle Fusion – Normal Spell: Fusion Summon 1 "Elemental HERO" Fusion Monster from your Extra Deck, by banishing Fusion Materials mentioned on it from your field or GY.]

"I banish Elemental HERO Avian and Elemental HERO Burstinatrix from my Graveyard—Fusion Summon!"

Both had already been discarded—Avian by Super Polymerization, and Burstinatrix during an earlier Graceful Charity. Their bond now reignited.

From wind and flame emerged a fusion hero. For Hoshino, this had just happened days ago. But for Jaden—it was a memory that shaped his heart for over a decade.

"This is the true form of a HERO that you first taught me ten years ago, Sensei! Fusion Summon—Elemental HERO Flame Wingman!!"

[Elemental HERO Flame Wingman ★★★★★★ (Level 6) | WIND | Warrior/Fusion/Effect | ATK 2100/DEF 1200]

Soaring from the fusion light, Flame Wingman crossed his arms and stood firmly beside Sieg.

One monster was the first Fusion Jaden ever learned—from Hoshino.

The other was a gift she entrusted to him at the start of his journey.

Now, these two heroes would decide the final outcome of this graduation duel.

"The Hero of Origins... and the Hero of Tomorrow.

This is the proof of everything you've taught me through dueling, Sensei—

my ultimate graduation answer!"
