Mechanics

Connection to the Soul Card World

A Soul Card Master initially draws one Soul Card from a selected Soul Card world. Through the Duel Instrument, they can observe their Soul Card follower's actions and may guide its choices if their in-world identity is accepted by that follower. 2

The Master does not directly control the Soul Card. Commands issued through the Duel Instrument are ultimately suggestions to a real individual within the Soul Card world; the follower can act independently or refuse to follow expectations. 149

• A Master's in-world identity already exists within the Soul Card world.
• Masters can determine limited traits such as appearance, clothing, and personality, while the identity's occupation, status, and relationships are fixed. 82
• Soul Card followers may act unpredictably, acquire cards without instruction, and influence the direction of their own world. 149

Duel Rules

Soul Card duels use Follower Cards and Spell Cards, with five field slots for each category. Playing a card normally requires Soul Points equal to its star rating. 2

Rule	Details
Tournament Soul Point limit	16 Soul Points per turn 2
Unlimited brawl rule	No upper limit on Soul Points 2
Professional Deck size	Exactly 40 cards 21
Soul Card role	Soul Cards provide the deck's central engine and fulfil a role comparable to an Extra Deck in other card games. 171
Form changes	A Soul Card can switch forms by paying the relevant Soul Point cost, allowing different effects and tactical roles. 6 25

Growth, Forms, and Variant Arts

Soul Cards can develop new forms as their linked individual gains strength, undergoes major changes, or reaches key milestones. Each form may have different star ratings, effects, and uses in a duel. 25

• A form's star rating corresponds to the linked individual's strength tier; the Dawn Continent's mortal First Tier through divine Fifteenth Tier broadly corresponds to one through fifteen stars. 2
• Forms compensate for the absence of Fusion, Synchro, Xyz, and similar extra-deck summoning systems, creating opportunities to change a duel's momentum. 25
• Soul Card Masters may modify card effects through special authority, but the effect must remain appropriate to the card's star level or the modification fails. 2
• A Follower Card can also receive a Variant Art when its linked individual changes. Unlike a Soul Card form, a Variant Art is selected before a duel and cannot be switched during it. 63

Card Acquisition

Card Sources

A Soul Card follower's experiences can generate additional cards for its Master. Spell Cards are broadly divided into three documented categories. 10

Card category	How it is obtained	Examples
Origin-type Spell Card	The follower learns a native skill or gains equipment from its world. 10	[Magic Ring], [Fireball Spell]
Behavior-type Spell Card	The follower performs an action with sufficient significance for the Duel Instrument to recognize it. 10	[Arson], [Crushing Blow Targeting the Groin]
Event-type Spell Card	The follower participates in and completes a major event; these are often powerful Permanent Spell Cards. 10	[Insubordination Rebellion]
Follower Card	The Soul Card follower gains followers or reaches sufficient affinity with another person. 10	Followers acquired by Alice
Environment / Field Card	Obtained from significant locations or events in a Soul Card world. 95 241	[Dragon Trial: Lava]

Multiple Soul Cards

A Soul Card Master normally draws only one Soul Card through the Duel Instrument, but can acquire additional Soul Cards through exceptional opportunities in their Soul Card world. 65

• A deceased Soul Card can sometimes be replaced by binding a direct bloodline descendant, while the original Soul Card remains usable in duels. This can leave a Master with two Soul Cards. 65
• If a Soul Card dies without a direct descendant, its Master loses their connection to the Soul Card world and their reliable source of new cards. 65
• Additional Soul Cards can also be acquired independently of this inheritance process, as demonstrated by Shen Sui obtaining [Star Abyss White Dragon Kishara]. 65
• A newly obtained Soul Card may be unusable until it reaches a complete or extractable state. 65

Uniqueness and Ownership

Soul Cards are unique. A Soul Card already bound to one Master cannot simply appear as another Master's Soul Card, though a related individual may still become an ordinary Follower Card or Spell Card. 379

• A bound Duel Instrument cannot be unbound or traded. 126
• Soul Cards can be inherited only by blood relatives. 126 379
• Unlike ordinary cards, Soul Cards are not subject to the usual Forbidden Card process. 2 180
• Ordinary cards may be prohibited from professional competition, but can remain usable outside recognized professional events. 325 498

Trading and Regulation

Soul Cards and other cards can be traded through Soul Card Shops. Buyers use Blank Cards, onto which the transaction system prints the purchased card data; shop transactions are anonymous to participants. 6

• External purchases are prohibited in the Duel Exam, where cards are checked through transaction codes. Candidates must assemble twenty eligible cards through their own Soul Card world. 6
• The Soul Card Association can review ordinary cards reported as excessively powerful and place them on the Forbidden Card list for professional play. 2 23
• Exploration Bureau exchanges are card-for-card rather than monetary transactions, prioritizing cards with practical value in their corresponding Soul Card worlds. 95
• The Time Flow Regulator can alter the passage of time between reality and the Soul Card world from 1:1 up to 1:16. 21

Reality and Extraordinary Power

Soul Cards are linked to real individuals and real worlds rather than being mere projections. This connection can eventually allow power, consciousness, and even physical manifestations to cross into reality. 375 379

• [Star Soul Astrologer Cong Tian] developed consciousness, communicated with its Master, and influenced reality through abnormal luck. 375
• The Duel Instrument's connection is not one-way: Masters can impose their will on Soul Cards, while Soul Cards can also transmit power back to their Masters. 379
• When confronting an opponent with an extraordinary aura, world restrictions may loosen and permit a Soul Card's power to transfer to its Master. 416
• During the Extraordinary Power invasion, Soul Card projections began appearing alongside Masters, particularly when they were threatened. 463 529
• Within Buffer Zone instances, invading entities have their extraordinary power transformed into Soul Cards and must kill Masters through Soul Card duels rather than direct ambushes. 692

Origin

The underlying Soul Card duel system and card-acquisition system were established by Vivian. The world's consciousness retains a backdoor that allows her to alter certain non-essential functions of the system. 287 552
