Honkai Star Rail: Best Sunday Team Composition Guide

Sunday has officially arrived, and if you’re considering pulling for him, you’re not alone. As a premium support tailored for summon-based allies, he is set to become a major game-changer in version 3.0 and beyond. However, his usefulness isn’t limited to future content—Sunday’s exceptional buffs make him an incredibly versatile support, capable of revitalizing older characters and enhancing a variety of team compositions.

Whether you’re looking to maximize his synergy with summon-heavy units or integrate him into other powerful setups, we’ve prepared three recommended team compositions to help you get the most out of Sunday’s abilities.

Best Sunday Teams In HSR

While Sunday is primarily known as a top-tier support for summon-based allies, his versatility extends far beyond that role. Thanks to his universal CRIT Rate and CRIT DMG buffs, Energy Regeneration, SP efficiency, and 100% Action Advance skill, he can seamlessly fit into almost any team composition.

DPS units that rely on high CRIT stats will benefit immensely from his support, making him a near-universal pick for offensive setups. That said, his strongest synergy remains with summon-based characters, where he can fully utilize his kit to its maximum potential. Below, we explore the best team compositions to take full advantage of his abilities

Sunday & Jing Yuan Team

Recommended Team Composition:
• Jing Yuan (Main DPS)
• Sunday (Support)
• Robin (Buffer)
• Aventurine (Sustain)

With Sunday’s arrival, Jing Yuan finally gets the dedicated 5-star support he needed to fully unleash Lightning Lord’s potential. Over time, Jing Yuan has fallen in the meta due to a lack of strong team synergies, but Sunday’s CRIT buffs and Energy Regeneration could bring him back into relevance.

Pairing Sunday with Jing Yuan ensures that Lightning Lord triggers more frequently and hits harder, significantly increasing his overall damage output. Robin further enhances the team by providing additional ATK and Action Advance buffs, making it easier for Jing Yuan to rotate his abilities efficiently. The final slot can be filled with Aventurine for sustain, though any healer or defensive support can work depending on your needs.

This setup allows Jing Yuan to shine once again, taking full advantage of Sunday’s game-changing support capabilities.

Sunday & Boothill Team

Recommended Team Composition:
• Boothill (Main DPS)
• Sunday (Support)
• Ruan Mei (Buffer)
• Lingsha (Sustain)

Sunday is a game-changing addition to Boothill teams, offering exceptional Energy generation, frequent Action Advances, and SP efficiency—all of which complement Boothill’s high-paced, aggressive playstyle. This setup follows the established Boothill team formula, but traditionally features Bronya. However, with Sunday effectively outperforming Bronya in terms of teamwide buffs and overall synergy, there’s no reason not to swap him in.

With Sunday boosting Boothill’s uptime, Ruan Mei providing additional Break Efficiency and ATK buffs, and Lingsha ensuring sustain, this team delivers consistent, high-damage output while maintaining strong survivability. If you’re a Boothill main, integrating Sunday into your setup will significantly elevate his performance and make your rotations even more fluid and impactful.

Sunday & Blade Hypercarry Team

Recommended Team Composition:
• Blade (Main DPS)
• Sunday (Support)
• Bronya (Buffer)
• Luocha (Sustain)

Hypercarry Blade teams have been a staple in Honkai Star Rail, traditionally relying on Sparkle and Bronya to ensure maximum uptime and turn priority for Blade. However, Sunday’s introduction changes the dynamic entirely, allowing you to replace Sparkle while still maintaining optimal performance.

Sunday’s 100% Action Advance, Energy generation, and powerful CRIT buffs make him an ideal enabler for Blade, ensuring he consistently stays at the top of the turn order while benefiting from a massive damage boost. Bronya remains a core part of the team, further advancing Blade’s turns and enhancing his damage. Lastly, Luocha provides sustain, ensuring Blade can self-sustain through HP loss while remaining in peak condition for damage output.

With Sunday in the mix, Blade hypercarry teams become even more reliable, allowing for smoother rotations, higher burst potential, and better overall team efficiency. If you’re looking to maximize Blade’s damage potential, Sunday is one of the best additions to his team.

Conclusion

Sunday’s arrival in Honkai Star Rail brings a new level of versatility and power to team compositions. While he excels as a support for summon-based characters, his universal CRIT buffs, Action Advances, and Energy regeneration make him an invaluable asset to almost any team.

Whether boosting Jing Yuan’s Lightning Lord uptime, fueling Boothill’s aggressive playstyle, or enabling Blade’s hypercarry dominance, Sunday elevates his allies’ performance across the board. His ability to replace existing supports like Bronya and Sparkle while offering even greater utility cements his place as one of the most impactful Harmony units in the game.

With Sunday in your lineup, you’ll have access to stronger, faster, and more efficient team rotations, ensuring your DPS units reach their full potential. If you’ve invested in him, experiment with different compositions, and you’ll quickly see why he’s such a game-changing support.
