In this fantasy world, there is a contract-type law item called the "God's Enlightenment Card". Divine revelation cards are activated when two parties holding a specific token agree to a "duel."
Mingpai core: The core rule of Shenqipai is to enforce information transparency.
While the game is active:
Both parties must clearly and unambiguously communicate their intentions and upcoming actions (at least publicly).
Any means of resistance (such as weapons, abilities, traps, spells, props used) and key effects must be announced before action or their principles must be revealed immediately.
Both sides' "trunk cards" (core hidden abilities or ultimate means) need to be revealed in part in their characteristics or areas before the game begins (not in full detail, but the opponent knows "what types of dangerous things the opponent has").
Deception, misdirection, and strategy are all based on "you know what I know, but you still win." The outcome depends on who can design more sophisticated serial calculations and psychological suppression based on public information.
