• When Xun Yu uses "Rouse the Tiger," he can select himself to be damaged if the target has Xun Yu in their attacking range.

• "Rouse the Tiger" and "Eternal Loyalty" can be used in unison. If Xun Yu loses the competition, he will take one unit of damage and can choose to activate "Eternal Loyalty" as a result.

• Remember, "Rouse the Tiger" causes direct damage. This damage cannot be avoided by playing an Escape or Negate card.

• "Eternal Loyalty" activates once per unit of damage received, not per instance. For example, if Xun Yu takes two units of damage, he can 'refill' two players' hands.

• "Rouse the Tiger" can only be used on a target who has at least one hand card, as the Compete mechanism requires this.

• Xun Yu excels in keeping his team well-stocked with hand cards. "Eternal Loyalty" is a strong deterrent against enemies targeting him, as it benefits his team greatly.

• "Rouse the Tiger" offers multiple tactical options. Xun Yu can use it to either damage an enemy or 'refill' a teammate's hand.

• Xun Yu can bypass powerful defensive abilities like Zhuge Liang's "Empty City" and Zhang Jiao's "Lightning Strike." Additionally, Xun Yu avoids retaliatory powers like Sima Yi's "Feedback" or Xiahou Dun's "Unyielding," as the source of damage is not him directly.

• Xun Yu's "Eternal Loyalty" becomes less valuable when his allies already have full hands, limiting his impact.

• In the early game, when players have full hands, Xun Yu is an easy target for enemies.

• "Rouse the Tiger" requires that another character be present within range to trigger its effects, making it less useful in one-on-one situations. "Eternal Loyalty" is also weaker when Xun Yu has no team members to benefit from it.

• Enhancing Ally Hand Sizes:
  Liu Bei can give away all of his hand cards and damage Xun Yu to activate "Eternal Loyalty," refilling his hand. This process can be repeated if Liu Bei draws the right cards, especially powerful if Liu Bei is the king with an extra unit of health.

• Maintaining Hand Advantage in Dueling Scenarios:
  Yan Liang and When Chou can use "Dueling Heroes" to deplete their hand cards and then Duel Xun Yu to refill their hand. As their power remains active, they can continue to Duel opponents.

• Supporting Card Draw for Aggressive Strategies:
  Yuan Shu often runs out of hand cards due to "Trite Rule." Xun Yu can keep him well-stocked with "Eternal Loyalty."

• Card Management for High-Cost Powers:
  Yuan Shao's "Random Strike" is expensive, but Xun Yu can replenish his hand each time he is hit. This enables Yuan Shao to use his power repeatedly to wear down enemies.

• Handling Multiple Damage Sources:
  Characters who can deal multiple units of damage can exploit Xun Yu's vulnerabilities. While "Eternal Loyalty" activates per damage, there may not always be multiple players in need of cards.

• Ignoring Refill Abilities:
  Zhang Chunhua's "Unfeeling" does not activate "Eternal Loyalty."

• Impact of Reduced Maximum Health:
  Ma Dai's "Sneak Attack" can lower Xun Yu's or his ally's maximum health, reducing the effectiveness of "Eternal Loyalty." Moreover, "Sneak Attack" does not allow "Eternal Loyalty" activation, as it does not constitute direct damage.

King

• • Xun Yu makes for a solid king. His "Eternal Loyalty" can keep his hand full and maintain a strong defense. However, players should be cautious early in the game, as Xun Yu is more vulnerable before the rebels start running out of cards.

Loyalist

• • Xun Yu is a valuable loyalist, particularly when paired with kings who need a consistent supply of cards. He is especially strong with Liu Bei as the king.

Rebel

• • Xun Yu’s "Rouse the Tiger" can be used to directly target the king, or he can manipulate the king into harming a loyalist. This makes him a strong rebel option.

Spy

• • Xun Yu is a poor spy. He relies heavily on teamwork, and his abilities become far less effective when he is isolated. His ability to manipulate enemies with "Rouse the Tiger" might work once, but it will lose effectiveness afterward. In a one-on-one situation with the king, Xun Yu's lack of raw offensive power limits his chances of success.

Xun Yu is not a beginner-friendly character, but in high-level play, he can shine as one of the best team players in the game. His ability to replenish his team's hand with "Eternal Loyalty" can significantly alter the flow of the game, allowing allies to be more aggressive with their cards. "Rouse the Tiger" adds an extra layer of strategy, giving Xun Yu options to damage enemies or help teammates. However, Xun Yu's effectiveness drops when isolated, as his abilities rely heavily on having a team. Players should use him tactically, manipulating situations to either benefit teammates or disrupt enemies, while carefully managing the risks associated with competing against enemies.

Xun Yu’s role in Sanguosha ties directly to his strategic brilliance during the Three Kingdoms period. One of his most famous strategies was the "Rival Tigers and One Prey" plan, designed to manipulate the growing tensions between Liu Bei and Lu Bu. At the time, Cao Cao was worried about the potential alliance between Liu Bei and Lu Bu, which would have put his own position in jeopardy. Xun Yu proposed granting Liu Bei an official decree to govern Xuzhou, while secretly encouraging him to eliminate Lu Bu. The plan was that either Liu Bei would remove Lu Bu, weakening his own position, or he would fail, and Lu Bu would eliminate Liu Bei for Cao Cao. This plan exemplifies Xun Yu's cunning ability to manipulate others to serve Cao Cao’s interests.

This historical cunning is reflected in Xun Yu’s ability "Rouse the Tiger" in Sanguosha, where Xun Yu manipulates other characters to deal damage on his behalf. Additionally, his "Eternal Loyalty" ability echoes his dedication to Cao Cao and his role as a staunch defender of the emperor's interests, ensuring his survival even in dangerous situations.
