• "Feign Illness" immunity effect applies to all forms of damage, including normal attacks, elemental attacks, and ability damage. It does not protect against losing health.

• Losing 1 health for "Feign Illness" is optional, and Sima Yi can choose not to activate this ability at the end of his turn.

• "Ghost Schemes" gives extra cards by the health points Sima Yi is missing from his maximum health at that point. 

• If Sima Yi loses his drawing phase due to Starvation, then he will not get to draw any cards from "Ghost Schemes" either.

• "Feign Illness" grants Sima Yi complete immunity to damage, making him an excellent target for absorbing dangerous attacks or weathering high-damage turns.

• "Ghost Schemes" ensures Sima Yi consistently has a large hand size, especially in the late game when he has lost significant health.

• Sima Yi's ability to trade health for immunity gives him control over the flow of the game, allowing for strategic positioning in critical moments.

• Relying on "Feign Illness" means Sima Yi can quickly lower his own health, leaving him vulnerable to game-ending situations if not carefully managed.

• "Feign Illness" only prevents damage. It does not prevent other negative effects that can occur.

• Sima Yi's abilities shine in shorter games, but in slow-paced matches, his reliance on losing health for benefits can backfire.

• His immunity and powerful card draw make him a high-priority target for opponents aiming to eliminate strong threats.

• Healing Support:
  Characters like Hua Tuo who provide healing can complement Sima Yi’s self-damage mechanics. By restoring his health after he uses "Feign Illness," they extend his survivability.

• Damage-Boosting Characters:
  Characters like Zhang Fei and Sun Ce, who excel at dealing rapid damage, are stopped by Sima Yi’s immunity. He can act as a shield, drawing attacks away from key allies.

• Health Loss:
  Characters that bypass damage and cause direct health loss are dangerous to Sima Yi since he is not protected with "Feign Illness". Zhang Chunhua is the best example of this.

King

• • Sima Yi's survivability and card draw allow him to maintain control and adapt to threats. However, his self-damage mechanics can be risky if poorly managed.

Loyalist

Rebel

• • His offensive potential through resource advantage makes him a potent threat to the King, especially in drawn-out battles.

Spy

• • Sima Yi thrives as a Spy, leveraging his abilities to survive and manipulate both sides of the conflict to his advantage.

Sima Yi is a versatile character who balances risk and reward through his unique abilities. "Feign Illness" provides unparalleled defensive capabilities, while "Ghost Schemes" ensures consistent access to resources. Effective use of his abilities requires careful health management and a strategic approach to timing his immunity. Players who enjoy tactical gameplay and calculated risks will find Sima Yi a rewarding choice.

Sima Yi was a brilliant strategist and politician during the Three Kingdoms period. Renowned for his cunning and resilience, he served under Cao Cao and later paved the way for the eventual rise of the Jin Dynasty under his descendants.

In Romance of the Three Kingdoms, Sima Yi is portrayed as a shrewd and patient adversary to Zhuge Liang and other opponents within the Wei court. His ability to feign weakness and wait for the opportune moment mirrors his in-game "Feign Illness" ability. For instance, his infamous feigned illness allowed him to ellude suspicion of Cao Shuang allowing him to perform a coup.

"Ghost Schemes" reflects his mastery of long-term strategy, often drawing resources and loyalty from unexpected places to secure his family’s dominance. His portrayal as a character of resilience and cunning makes him an enduring symbol of strategic brilliance in Chinese history and the Sanguosha game.
