• The target of "Expand and Recover" can be any player, including Cao Rui himself.

• "Expand and Recover" is activated on a 'per instance' basis. If he takes more than one damage at a time, he will activate "Expand and Recover" only once. If the judgment is black, the amount of damage is taken into account.

• When using "Clear Insight", Cao Rui must give all hand cards to the chosen player. He will retain possession of any equipment that he has.

• If Cao Rui does not have any hand cards, he can still use "Clear Insight" to give the phase to another player. 

• The extra phase granted by "Clear Insight" does not affect the player order. The chosen player performs their actions immediately after Cao Rui's turn ends. Then the player that comes after Cao Rui resumes the standard turn order.

• If a player is selected for "Clear Insight", they only get an Action Phase and not an entire turn. This means that they do not perform their Judgment Phase or Drawing Phase. This also includes their discard phase afterwards. They simply play whichever actions, and then complete the ability.

• Only Wei-aligned characters are eligible to heal Cao Rui using "Rise and Decline".

• Each Wei character decides individually whether to heal Cao Rui for "Rise and Decline".

• If a character recieves damage from healing Cao Rui, the damage does not have a source. Neither Cao Rui nor his source causes the damage from "Rise and Decline".  

• Cao Rui can mitigate damage with "Expand and Recover" or grant a vital turn to allies with "Clear Insight," making him invaluable in cooperative strategies.

• "Rise and Decline" provides a powerful, albeit costly, way to keep Cao Rui alive during critical moments, when playing as the King.

• "Expand and Recover" ensures that every instance of damage contributes to the team's healing or resource generation, making Cao Rui especially resilient.

• "Rise and Decline" relies heavily on having Wei-aligned allies. Without them, the ability loses value.

• Using "Clear Insight" can leave Cao Rui vulnerable, especially if the recipient of his hand cards does not capitalize on the extra phase.

• Cao Rui lacks direct attack abilities, making him reliant on allies for dealing significant damage.

• Wei Allies with Strong Durability:
  Allies like Cao Ren or Xiahou Dun are excellent for supporting Cao Rui during "Rise and Decline," as they can mitigate the damage they receive after healing him.

• Card-Dependent Characters:
  Characters such as Dian Wei or Liu Bei benefit greatly from "Clear Insight," as they can make the most of the extra play phase and hand cards Cao Rui provides.

• Judgment Tinkerers:
  Characters who manipulate judgments, like Zhang Jiao or Sima Yi, pair well with "Expand and Recover" to ensure favorable outcomes.

King

• • Cao Rui shines as King due to "Rise and Decline," which can keep him alive in dire situations. His support abilities also encourage loyalists to protect him.

Loyalist

• • As a loyalist, Cao Rui's team-oriented abilities can bolster the King's defenses and provide key turns to allies.

Rebel

• • Cao Rui’s abilities can be useful in draining the King’s resources, but his lack of offensive options may limit his direct impact.

Spy

• • Cao Rui does not make a good spy.  "Clear Insight" requires an ally and the spy does not have one. "Expand and Recover" can help keep him alive, but he doesn't have enough with just that to contribute much to the game. 

Cao Rui's abilities make him a strategic and supportive general who excels in preserving team momentum and managing resources. However, his effectiveness relies on team synergy and careful timing of his abilities, particularly "Rise and Decline." His strongest role is King, where his survivability can dramatically shift the tide of battle. Players should focus on maximizing his resource management abilities while safeguarding him from aggressive opponents.

Cao Rui was the second emperor of Cao Wei, succeeding his father, Cao Pi. Known for his cultured demeanor and administrative competence, he consolidated his rule during a period of political and military stability. Despite facing internal challenges and external threats, Cao Rui maintained the stability of the Wei regime and invested in cultural and architectural projects.

In Sanguosha, Cao Rui’s abilities reflect his historical emphasis on resilience and strategic delegation. "Expand and Recover" represents his ability to recover from setbacks and distribute resources effectively, while "Clear Insight" symbolizes his wisdom in delegating authority. His king ability, "Rise and Decline," mirrors the sacrifices and support he demanded from his subordinates during moments of crisis, emphasizing his reliance on the loyalty of Wei’s officials and generals.
