Guo Jia is a high-risk, high-reward character with a focus on judgment manipulation and card advantage. His ability to Exile generals makes him a powerful disruptor, but his reliance on luck and lack of direct offense can be major drawbacks. He is best used in a role where he can capitalize on his unique strengths without being an immediate target.

Guo Jia was one of Cao Cao’s most valued strategists, known for his intelligence and foresight. His early death at the age of 38 was considered a great loss to Wei.

His card abilities reflect both his wisdom and his untimely demise—"Strange Assistant" represents his ability to turn adversity into advantage, while "Stroke of Brilliance" showcases his strategic foresight in distributing resources.
