Seven Knights Re:BIRTH: Shinobu & Yoon Gun Arena Team

To run the high-tier Arena cleave composition in Seven Knights Re:BIRTH, build your lineup around Shinobu, Yoon Gun, Sunran, Hayun, and Dongyeong. This setup replaces traditional Radgrid, Giyu, and Yoon Yoon frontline teams by securing team speed attack, stripping enemy defensive barriers on turn one, and executing burst skill rotations before opposing Yoon Gun lineups can retaliate.

Core Roster Roles and Synergy

The lineup distributes responsibilities across two offensive carries, two utility enablers, and an opener to decide matches in early skill cycles:

Hero	Primary Role	Core Combat Function
Shinobu	Opener / Speed Disruptor	Supplies high base speed, applies anti-heal debuffs, and softens frontline targets.
Dongyeong	Buffer / Turn Controller	Strips enemy defensive shields, manipulates turn timing, and boosts team speed attack.
Yoon Gun	Primary Magic Nuker	Delivers lethal area-of-effect burst after enemy buffs and barriers are removed.
Sunran	Secondary DPS / Finisher	Pierces residual barriers and cleans up units surviving threshold mechanics.
Hayun	Support / Buffer	Provides defensive stabilization, protects squishy carries, and scales team damage.

This formation moves away from defensive attrition shells. Older endurance compositions relying on Radgrid and Giyu struggle against rapid buff removal and penetrating burst damage, leaving slow units unable to absorb modern offensive rotations.

Hero Stat and Gear Priorities

Optimizing substats across this roster ensures proper skill queuing and turn advantage:

Shinobu: Target maximum Speed alongside Effect Hit and Critical Rate. Shinobu requires the highest individual speed on the squad to disrupt opposing openers with debuffs.
Dongyeong: Prioritize Speed second to Shinobu, ensuring Dongyeong acts before opposing carries. Allocate remaining stats to HP and Block to survive opening chip damage.
Yoon Gun: Maximize Magic Attack, Critical Rate, and Critical Damage. Yoon Gun needs adequate speed to follow your openers, but pure offensive scaling takes priority to guarantee clean board wipes.
Sunran: Build Attack, physical piercing, and Critical stats, tuning speed to cycle directly behind Yoon Gun.
Hayun: Focus on survivability through HP, Defense, and moderate Speed, keeping support passives active to protect the team from counter-attacks.

Team Speed Attack and Skill Order

High-tier Arena mirror matches often depend on winning the initial team speed attack check. A higher cumulative speed total gives your squad the opening initiative. Configure your skill order to prevent carries from wasting attacks on enemy shields:

Dongyeong (Buff Strip): Cast utility skills first to remove active barriers, invulnerability states, and defensive buffs from the enemy frontline.
Shinobu (Disruption): Trigger opening attacks to apply anti-heal and debuff pressure across the opposing formation.
Yoon Gun (Main Burst): Unleash primary area-of-effect skills to eliminate opposing carries and heavily damage remaining targets.
Sunran (Cleanup Cleave): Fire piercing skills to eliminate any heroes surviving on low-health or death-prevention mechanics.
Hayun (Stabilization): Execute recovery and support buffs to restore the party and absorb potential counter-attacks if targets remain.

Handling Yoon Gun Mirror Matchups

When facing opposing Yoon Gun teams, winning the speed attack roll allows the Dongyeong-to-Yoon Gun rotation to eliminate the enemy formation before they act.

If the opponent wins the opening speed roll, your survival depends on Hayun's defensive stabilization. Provided the enemy fails to strip your defenses fully on turn one, Hayun's survivability buffs mitigate the initial burst. Once the enemy's opening volley concludes, use Dongyeong to strip opposing buffs immediately, enabling Yoon Gun and Sunran to wipe the enemy squad on the counter-turn. Check Arena match replays regularly to confirm your heroes maintain the proper skill queue order without cooldown desynchronization.
