Seven Knights Re:BIRTH Sunran Shinobu Yoon Gun Arena Deck

To run the Sunran, Shinobu, and Yoon Gun magic team in Seven Knights Re:BIRTH Arena, position Sunran in a protected damage slot, speed-tune Shinobu to act directly after her debuffs, and build Yoon Gun with high Speed and Effect Hit to lock down enemy actions.

This offensive composition counters stall lineups and bulky frontlines by stacking magic vulnerability, stripping hit-count barriers, and cycling burst damage before opponents can stabilize their healing engines.

Team Composition and Role Breakdown

The core trio requires a durable tank to absorb initial physical burst and a flexible support unit to assist with cleansing, buffs, or turn cycling. Deploy the team in a four-front, one-back or three-front, two-back formation so your squishier magic carries receive backline protection and offensive stat bonuses.

Stat Priorities and Gear Tuning

Your gear setup must ensure Yoon Gun disrupts early, Sunran softens the enemy lineup, and Shinobu acts immediately afterward to clean up survivors.

• Sunran: Prioritize Magic Attack, Critical Hit Rate, and Critical Damage on weapons and accessories, followed by Lethality or Piercing. Equip Maximum HP and Block Rate on armor to prevent backline snipes.
• Shinobu: Balance Speed and Magic Attack. Tune her Speed stat slightly below Sunran's so she attacks debuffed targets. Prioritize Critical Damage and Weak Point substats to maximize her multi-hit pressure.
• Yoon Gun: Maximize Speed on weapons to contest the opening turn. Equip defensive armor with Block Rate, Damage Reduction, and Maximum HP. Prioritize Effect Hit on substats so his crowd control lands reliably against teams with high Status Effect Resistance.
• Frontline Tank: Stack Block Rate, Defense, and Maximum HP or Damage Reduction to guarantee your carries survive opening physical skills.

Exclusive Equipment Investment Order

Exclusive gear materials are limited, so upgrade equipment according to each hero's impact on your win condition:

1. Sunran: Prioritize her exclusive piece first. It raises her base magic amplification and grants defense-ignoring properties to her main burst skills.
2. Shinobu: Upgrade her piece second. It increases her skill multipliers and improves utility against buffed or shielded targets, enabling her to secure kills on surviving bruisers.
3. Yoon Gun: Upgrade his piece last. It enhances his disruption passives and cooldown reduction, providing stability if matches extend beyond the opening rounds.

Arena Execution Strategy

Your primary goal is securing an early numerical advantage within the first two active skill rotations:

• Against defensive stall and tank decks: Sunran’s debuffs bypass heavy armor, while Shinobu’s multi-hit attacks quickly deplete immunity layers and hit-count barriers. Focus your targeting on the opponent's primary healer or defensive support to break their sustain loop early.
• Against physical burst squads: Survival depends on your frontline tank absorbing the opening volley or Yoon Gun landing an early crowd-control interrupt. Once the opposing burst phase concludes, trigger Sunran’s AoE rotation to wipe fragile enemy carries before they take a second action.
