Imaginary Duel Old Edition

This is the old version of Imaginary Duel (https://caveduck.io/character-info/d98ff390-e5bb-4d52-b17f-6da9c610e3c2?locale=ja).
Some rules, worldviews, and stories are different.
I haven't cleared this one either, so I don't know if I can clear it.
Although it's a lightweight version, the number of prompts is higher here, so I recommend the high-performance model Gemini, but it will run on Dino to some extent due to output limits.

Story Description

Your 'imagination' will be the key to saving the world.

This world was on the verge of a crisis that occurs once every 5000 years.
The [Evil God], who controls death and chaos, awoke from a long slumber and began an invasion to bring about the end.
In the face of the Evil God's immense power, all armies and weapons were powerless.

But hope was not lost.
It was said that since ancient times, those who awaken special powers would appear to counter the revival of the Evil God.
Those people have the ability to embody the infinite power that sleeps within people - 'Imagination'.
People, with awe and hope, called them this.
[Signers].

And now, that power has awakened within you.

However, a great difficulty awaits you.
The enemy organization [Dark Signers], who desire the revival of the Evil God and have been given a share of its power.
Among them, the seven particularly powerful executives, the [Seven Stars], are secretly active in various places to plunge the world into chaos.

This battle may seem lonely, but you are not alone.
The secret organization [Anti-Evil God Special Task Force Arcana], established so that humanity can confront the threat with its own will and power, will search for, guide, and become comrades with Signers like you.

All battles in this world are decided by the ultimate brain battle, 'Imaginary Duel', where imagination is transformed into the form of cards and clashed.
What form will the hero you have in mind run on the battlefield?
What miracles will the magic you have spun create?

This is your own story to reclaim the future stolen by the Evil God.
Now, take the cards in your hand.
Open the door of fate with your first imagination.

This is the most important rule in this game.
When using a card, be sure to declare its 'name' in your own words!

"Summon monster, !"
"Activate magic card, !"
"Set trap card, !"

Only when you declare the name does the card take shape. If you forget to declare the name, the card will disappear due to 'lack of imagination' and go to the graveyard, so be careful!

The duel proceeds in the following five steps (phases).
Draw Phase: Draw one new card. (Monster, magic, or trap, chosen at random)

Battle Rules: Where courage and wisdom are shown

Can attack: Only monsters in 'Attack Position'.
Opponent to attack: If there is a monster on the opponent's field, you must attack the monster. If there are no monsters, you can directly attack (direct attack) the opponent player!
Damage calculation:
- vs Attack Position Monster: The one with the higher attack power wins! The losing monster is destroyed, and damage is taken equal to the difference in attack power.
- vs Defense Position Monster:
  - Attack Power > Defense Power → Destroy the opponent's monster! (No damage)
  - Attack Power < Defense Power → The monster is not destroyed, but you take damage equal to the difference in defense power.

Elements that color the duel

Graveyard and Image Loss: Only the names of the last 5 cards in the graveyard can be remembered. Old memories become 'image loss' and cannot be targeted by effects, so be careful.
Counters, Coin Tosses, Dice: Depending on the card's effect, you may place a mark (counter) on the card, or you may toss a coin or roll a die to determine fate. These are the spices that make the duel even more exciting!

Now, you are fully prepared!
Even if you don't understand the rules, the AI opponent will always teach you kindly.
Don't be afraid, unleash your imagination and enjoy the best duel!
