At the beginning, I traveled through Cheng Qisara to the DM world

"Attack power 3500, it turns out Isis is so powerful!" Dark Yugi murmured.

"It's terrible, so terrible. My sister gave her all from the beginning!" Malik laughed.

"Activate the special effect of [Gravekeeper Psychic]. During this turn's End Phase, add 1 [Gravekeeper] monster or 1 [Royal Valley of Eternal Sleep] card from your deck to your hand."

"Fight, [Gravekeeper Psychic] attacks [X-Leader Ganon]!"

"Too naive! When you activate the Trap Card [Attack Guide Armor], or your opponent's monster declares an attack, you can choose 1 of the following effects to activate.

1. Destroy the attacking monster.

1. You can activate this effect by targeting yourself or a monster on your opponent's field other than the attacking monster, and the attack target will be transferred to that monster for damage calculation."

"I choose effect one, destroying the [Gravekeeper's Psychic]!"

"It's useless!" Qisala muttered.

The [Gravekeeper Psychic] on Isis's field put on armor, and the red eyes on the armor glowed, as if they were about to explode.

"Boom!"

The explosion sounded, the smoke cleared, and the [Gravekeeper's Psychic] remained on the scene.

"What's going on!" Kaiba said in surprise.

"That's because [Gravekeeper Psychic] cannot be destroyed by the effect of [Royal Valley of Eternal Sleep] as long as [Royal Valley of Eternal Sleep] is on the field."

"What, there is such an effect!"

"That's it. The battle continues. [Gravekeeper Psychic] attacks [X-Leader Ganon]!"

"Activate the Counter Trap Card [Attack Disabling], Isis. Although your [Gravekeeper Psychic] cannot be destroyed by the effect, it will still become the target of the effect!"

"Due to the effect of [Attack Incapacity], your [Gravekeeper's Psychic]'s attack is negated, and this round's Battle Phase ends!"

The attack of [Gravekeeper's Psychic] stopped.

"It's okay, I'll cover a card and the turn ends."

"At this moment, activate the effect of [Gravekeeper's Psychic] and add [Gravekeeper's Descendant] from your deck to your hand!" (Hand remaining: 3)

"I didn't expect Isis to be so strong. I underestimated her. The most important thing now is to deal with her field magic cards!" Kaiba thought to himself.

"My turn, draw a card!"

"I activate the Spell Card [Pot of Greed] from my hand and draw two cards from my deck."

"Then summon [Z-Metal Track] from your hand in Attack Position!" (1500/1300)

"I activate the effect of [Y-Dragon Head], and this equipped card can be Special Summoned. Therefore, the attack power of [X-Boss Cannon] is restored to its original value!"

[X-Boss Cannon] (1800/1500)

【Y-Faucet】（1500/1600）

"I banish [X-Boss Cannon], [Y-Dragon Head], and [Z-Metal Tracks], and Special Summon [XYZ-Dragon Cannon]!" (2800/2600)

"Activate the Quick-Play Spell Card [Shrink] from your hand. This card can target 1 face-up monster on the field. That monster's original ATK is halved until the end of this turn."

"I will halve the original attack power of the Gravekeeper's Esper, so the Gravekeeper's Esper's attack power is now 2500 points!"

[XYZ-Dragon Cannon] fired a shock wave, and [Gravekeeper Psychic] was destroyed!

Isis Ishdar LP4000＞3700

"This will allow you to destroy the cards on the field. I activate the special effect of [XYZ-Dragon Cannon], discarding a card from your hand to destroy a card on the field."

Kaiba said as he discarded a card.

"I want to destroy the [Valley of the King's Eternal Sleep]!"

"Seto, you're not going to succeed. Activate the Trap Card [Ritual of the Spirit] to Special Summon 1 monster in your Graveyard with [Gravekeeper] in its name. This card cannot be activated by [Valley of the King's Long Slumber]."

"I will summon [Gravekeeper Prayer] from the graveyard in defense position!" (1500/1500)

"With the effect of [Gravekeeper's Prayer], as long as [Royal Valley] is on the field, the opponent cannot activate Field Spell Cards, and Field Spell Cards cannot be destroyed by the opponent's effects."

"Therefore, your [XYZ-Dragon Cannon] cannot destroy the [Valley of the King's Long Sleep]!"

"Next, the effect of [Gravekeeper's Prayer] increases the DEF of this card by the number of monsters with [Gravekeeper] in their names in your Graveyard x 200."

"There are three [Gravekeeper] monsters in my graveyard, so [Gravekeeper's Prayer]'s defense is increased by 600 points. In addition, due to the effect of [Royal Valley of Long Sleep], [Gravekeeper's Prayer]'s attack and defense are increased by another 500 points!"

【Gravekeeper Prayer】（2000/2600）

"Damn it! I covered a card, and the turn is over!" (Remaining cards in hand: 0)

"Yugi, Kaiba looks like he's having a hard time." Jonouchi said.

"Yes, Isis is so oppressive that even Kaiba finds her difficult to deal with," Yugi said.

"But this situation won't bother Kaiba. If he falls here, Kaiba will have a lot of fun." Kisara said with a smile.

"It seems that you trust Kaiba very much, Kisara." Yugi said.

"Of course. After all, we've been with him for such a long time, this little setback won't faze him."

"My turn, draw a card!"

"I summon [Descendant of the Gravekeeper] from my hand!" (1500/1200)

"Due to the effect of [Royal Valley], attack and defense power increased by 500 points."

[Descendants who guard the tomb] (2000/1700)

"Then I activate the Spell Card [Azalea Throne of the Valley of the King's Long Sleep] from my hand. This card can activate one of two effects: one to add a [Gravekeeper] monster from my deck to my hand, and the other to summon a [Gravekeeper] monster from my hand."

"Therefore, I summon [Gravekeeper Summoner] from my hand!" (1200/1500)

"Due to the effect of [Royal Valley], attack and defense power increased by 500 points."

"Isis, even if you gather so many small monsters, you can't destroy my [XYZ-Dragon Cannon]!" said Kaiba.

"That's hard to say. Activate the effect of [Gravekeeper's Descendant] to release a [Gravekeeper] monster other than this card. You can select and destroy one of your opponent's cards."

"I want to liberate the [Gravekeeper Summoner] and destroy the [XYZ-Dragon Cannon]!"

"This instant, activate the effect of [Gravekeeper Summoner]. When this card is sent from your field to your Graveyard, add 1 [Gravekeeper] monster from your deck with 1500 or less DEF to your hand."

"I want to choose [Grave Guard Ambush]
