• "Roar" is Zhang Fei's ability, allowing him to attack as many times as he likes during his turn without restrictions.

• "Fighting Saint" is Guan Yu's ability, which allows him to use any red card as an Attack.

• Guan Xing and Zhang Bao can activate "Paternal Souls" at any time to produce an Attack using two hand cards. They can use it outside of their turn when responding to Duels or Barbarians, but they only gain "Roar" and "Fighting Saint" if they successfully deal damage with an Attack during their turn.

• The color of the Attack produced by "Paternal Souls" depends on the two cards used. If both cards are the same color, the Attack will have that color. If they are different colors, the Attack is colorless, functioning like the Serpent Spear.

• "Paternal Souls" allows Guan Xing and Zhang Bao to unleash strong offensive potential, especially when they successfully damage an opponent, triggering "Roar" and "Fighting Saint."

• Unlike the original version, "Paternal Souls" no longer relies on specific colored cards to activate, reducing the reliance on luck and making it more dependable.

• Guan Xing and Zhang Bao can even target an ally with "Paternal Souls," then redirect their offensive power against their enemies, providing some flexibility in activation.

• "Paternal Souls" requires sacrificing two hand cards to produce an Attack, which is costly, especially if the Attack is neutralized by an opponent's Escape card.

• The loss of two cards per Attack can make Guan Xing and Zhang Bao more vulnerable if their offense is stopped or if they are left without enough cards to defend themselves.

• Card-Gifting Allies:
  Characters like Liu Bei, Guo Jia, Xu Shu, and Chen Gong are excellent allies for Guan Xing and Zhang Bao. Their ability to give cards allows Guan Xing and Zhang Bao to fuel their "Paternal Souls" ability more consistently, ensuring they can maintain their offensive momentum and frequently trigger their powerful effects.

• Hand-Replenishing Support:
  Xun Yu is particularly valuable due to his "Eternal Loyalty" ability, which can refill Guan Xing and Zhang Bao’s hand after they expend it during their turn. This becomes especially potent when Guan Xing and Zhang Bao activate "Paternal Souls" and launch multiple attacks in a single turn, allowing them to extend their assault with renewed resources.

• Retaliatory Defenders:
  Xiahou Dun, Fa Zheng, Sima Yi, and Cai Wenji pose a significant challenge to Guan Xing and Zhang Bao, as their retaliatory abilities trigger with every instance of damage. This makes it dangerous and costly for Guan Xing and Zhang Bao to attack these characters multiple times, potentially suffering severe consequences for their aggression.

• Damage Mitigation:
  Chen Gong's "Delayed Wisdom" can neutralize Guan Xing and Zhang Bao’s repeated attacks, as it prevents them from dealing damage multiple times within the same turn. This counters their offensive power, making it difficult for them to unleash their full potential.

• Escape Artists:
  Lu Meng and Zhen Ji are tricky opponents for Guan Xing and Zhang Bao, as they excel at playing Escape cards. Their proficiency in evading attacks makes it difficult for Guan Xing and Zhang Bao to land the crucial hit needed to activate "Roar" and "Fighting Saint," reducing their offensive capability.

King

• • Without relying on random chance to activate "Paternal Souls," Guan Xing and Zhang Bao are slightly better as kings compared to their original version. If they manage to kill a rebel, they gain more cards and potentially have a chance to kill even more. However, their lack of strong defensive options may make them vulnerable in this role.

Loyalist

• • They make for a strong loyalist. Their offensive potential can wipe out rebels quickly, especially when they start gaining cards after each rebel kill. The cycle of drawing three cards per rebel defeated ensures they remain a threat.

Rebel

• • Guan Xing and Zhang Bao can be powerful rebels, especially when they focus their attacks on the king. With their ability to unleash numerous attacks in one turn, they can quickly turn the tide of the game if they find the right opportunities.

Spy

• • Guan Xing and Zhang Bao are not suited to the spy role. Their abilities focus on dealing consistent damage, but without strong self-defense or survival mechanisms, they are not likely to last long in a game where they must outlast both sides.

Initially, we thought this version of Guan Xing and Zhang Bao was weaker than their original counterpart, but after testing them in multiple games, it became clear that they are equally strong, if not better. The new "Paternal Souls" offers a more reliable activation condition, even though it comes with a higher card cost. A skilled player can target allies to ensure the ability activates, allowing them to take full advantage of "Roar" and "Fighting Saint."

Guan Xing and Zhang Bao were the sons of the legendary heroes Guan Yu and Zhang Fei, respectively. Both men were born into a legacy of military prowess and heroism, and they spent their lives trying to live up to the high standards set by their fathers. During the later campaigns of Shu, they were often at the forefront of battles, continuing the fight against Wei and seeking to avenge their fathers' deaths.

In Romance of the Three Kingdoms, both sons are depicted as brave and capable warriors. After the death of their fathers, they swore revenge against the enemies of Shu, particularly Cao Wei. Guan Xing was known for his intelligence and courage, while Zhang Bao inherited his father’s immense strength and ferocity. Together, they were among Zhuge Liang's most trusted generals during his northern expeditions.

Their ability, "Paternal Souls," is a tribute to their lineage, drawing on the powers of Guan Yu's "Fighting Saint" and Zhang Fei's "Roar." These abilities reflect the qualities they inherited from their fathers—Guan Yu's discipline and precision with his red cards and Zhang Fei's unrelenting aggression in battle. Their history of working together to honor their fathers and protect the kingdom of Shu is mirrored in their game abilities, which focus on coordinated, powerful attacks and capitalizing on their family’s strengths.
