Archer of Inferno (Saber)
Ishtar (Rider)
All Servants that were discussed for tier placement or movement are detailed below.
Staff were allowed to assign the following scores.
After some debate, the staff generally agreed to have only EX-/A+/B+/C+/D+ tiers aside from the standard EX/A/B/C/D/E, so for the purposes of tiering the average scores were then rounded to the closest score to obtain the final tier as below. 
As a result, any A-/B-/C-/D-/E+/E- votes, after averaging, would round out to the next closest tier.
5 Star Servants
Mysterious Executor C.I.E.L.
Tier A+
A certain mysterious executor "C.I.E.L." appears during the Summer 2026's first half, as an ST Buster Moon Cancer. She is the first Servant in the roster to be capable of forcing all Command Cards to be replaced with her own for a turn. When combined with her massive 100% Critical Damage buff skill, and all of her buffs that activate when normal attacking with her Cards, she can make extremely good use of having all Cards to herself. With some powerful Buster crits from guaranteed Cards, she can manage quick clears on odd enemy compositions, sometimes without even having to use her NP. Her NP itself is impressve, having Sure Hit, Ignore DEF, and an NP Damage buff before dealing damage to a single enemy, and additionally deals supereffective damage against Demonic trait enemies. It also has a high chance to inflict Instant Death, and gives her 20% NP charge after use. In her kit, she also has a 10% NP regen ability for a lengthy 5 turns, along with 10% NP charge when attacking with Buster Cards (including her NP), enabling her to refund 40% with her NP just with her kit alone. On top of this, she has a self 50% NP battery, giving her ample access to her NP. Defensively, although she lacks a hard defensive option, she has a massive 100% DEF buff that lasts for 3 hits across 3 turns, and also has decent HP regen as well as a small amount of healing whenever attacked. Utility-wise, aside from her Card-fixing and NP effects, she has 5 turns of 50% Debuff Resist, 100% Buff Removal resist, and when attacking with Arts Cards, she can remove Guts, has a chance of draining NP bar from the enemy, and also debuffs the enemy's healing received. Last but not least, despite being Moon Cancer, she has a passive that gives her offensive Class Advantage against Saber Class, giving her an additional niche for damage dealing. The primary offensive ability she lacks is the ability to generate a sum of Stars on demand, which would need to be provided either from supports or CEs. Overall, CIEL is a force to be reckoned with, being more than self sufficient, and only reaching greater heights with the assistance of premiere Buster Supports.

BB (Dubai)
Tier A
BB (Dubai) arrives late in the second half of Summer 2026, and is an Arts Moon Cancer capable of selecting either an AoE damage dealing NP or a supportive NP. The damaging version of her NP is the default, and deals Special ATK bonus damage against both Heaven and Star attribute, as well as supereffective damage against the special trait she can apply using her second skill. Additionally, it has a small Arts Resist debuff it applies after damage. The supportive version of her NP gives all allies 1 turn of Invincibility, Debuff Immunity, buffs NP Damage, and charges the gauge by 30-50% for all allies with the trait she can apply from her first skill, which affects all allies except herself. Her skill kit provides offensive support to the party, although some is restricted to Moon Cancer or Living Human allies. She gives an Arts buff and up to 20% NP Gauge to all allies, and specifically for Moon Cancer/Living Human allies, she gives NP Damage, NP Gain, Crit Star Drop Rate, and Crit Damage buffs. As a result, her supportive capacity is maximized only with select Servants. For herself, her third skill provides a 50% NP battery, decreases her own skill cooldowns by a turn, and allows her to select which version of NP she will use for the next 3 turns. She also has a bit of debuff utility from her second skill, which removes buffs and decreases ATK and Arts Resist for all enemies. Taken together, BB (Dubai) is a somewhat unique and flexible Servant who works well in both multi-damage dealer compositions, as well as in the support role with Servants that are either also Moon Cancer or have the Living Human trait.
1BB (Dubai): x -> A (Avg Score: 8.78) -

4 Star Servants
Dobrynya Nikitich (Lancer)
Tier A
Dobrynya Nikitich dons a swimsuit and joins the Summer 2026 festivities as an ST Arts Lancer, complete with both anti-Earth and anti-Dragon bonus damage. Her NP, in addition to its Special ATK bonus against Earth attribute, also inflicts NP Seal and decreases Arts Resist after damage. She has multiple sources of NP Gauge, including a 30% NP battery skill, as well as 10% NP regen across 3 turns, which comes with a 3-turn NP Gain buff. She also has multiple offensive buffs in her kit, including Arts, ATK, Crit Damage, Special ATK vs Dragon, and a further ATK/Crit Damage/DEF boost whenever on a near-water battlefield. To supplement her Crit Damage buffs, she has multiple ways to generate Stars, including up to 30 Stars on demand, and up to 10 additional Stars per turn. However, she is lacking defensively, having a small HP regen skill and no hard defensive options to speak of. Dobrynya overall is a well-rounded offensive Servant, covering both NP and Card damage dealing avenues, but she is heavily reliant on supports for survival. In most cases however, given her relatively common trait based damage bonus, as well as ample sources of Crit and NP Gauge, she often can decimate enemies before defense becomes an issue.

Xu Fu (Avenger)
Tier B+
Xu Fu (Avenger) debuts during the Summer 2026 Event, complete with chainsaw as an ST Buster Avenger. She is the second ST Buster Avenger to grace the roster, with the first being Jeanne d'Arc (Alter). Her NP has a high chance of inflicting Instant Death, and will grant the party an ATK buff if the Death effect succeeds. Her NP also deals supereffective damage against Human attribute enemies, which are decently common. In her kit, she has multiple sources of NP Gauge, including a 30% battery, as well as a smaller 10% battery for the entire party. She also gives an NP Regen buff, providing 10% charge per turn across 3 turns. Additionally, she provides Overcharge support to the entire party, which also includes her own NP's anti-Human supereffective multiplier. Aside from those effects, the rest of her buffs are offensive buffs for herself, which include Arts/Buster/NP Damage/Instant Death Success Rate, along with small Special ATK multipliers for each of Poison, Curse, and Burn ailments. This means that if the enemy is inflicted with all three ailment debuffs, her Special ATK multiplier is maxed at 60%. However, she does not have any way to inflict these debuffs on her own, relying on allies or Command Codes to do so. She is a solid damage dealer with decent party support capacity. However, she can struggle to hit hard against enemies where her bonus traits are not applicable.
1Xu Fu (Avenger): x -> B+ (Avg Score: 8.33) - 
2[NorseFTX - B][WhiteRabbit - A][Rathilal - B]
Tenochtitlan (Moon Cancer)
Tier B+
Tenochtitlan gets a swimsuit version during Summer 2026, and while she is still an AoE Quick Servant, she is instead Moon Cancer Class. Her NP deals supereffective damage against Super Giant enemies, and also applies Ignore Invincible and buffs her NP damage before dealing AoE damage. It also applies a small DEF debuff after dealing damage for 3 turns. Her skill kit contains a mix of defensive utility and offensive support. She notable can apply Taunt to herself for 3 turns, which also coincides with a hefty 50% DEF buff and the ability to gain a small NP damage buff every time she is attacked. She also has a 1-turn Evade skill to help mitigate the damage she receives, along with a small HP regen effect that helps offset the damage she receives. She also provides a party-wide 20% NP charge skill. Offensively, she provides a the party with an ATK buff (with the very minor demerit of giving the enemies a small ATK buff as well), and specifically for Bunny Servant trait allies, she provides a Crit Damage buff and a 1-turn skill cooldown reduction. She also has a further Quick and Buster buff for herself. In some ways, she is very similar to her Pretender version, with key differences being her Summer version's access to Taunt, hard defense, and the anti-Super Giant / Ignore Invincibility on her NP. She can technically loop with sufficient Quick Support, although her middling refund makes looping somewhat uncomfortable. However, she can lay claim to the title of being the very first Quick Servant in the Moon Cancer Class. It is usually unlikely to find waves of Avenger enemies in farming nodes, but when they do appear, for Masters that primarily have Quick Support options, she can be a beneficial member of the roster to have.
1Tenochtitlan (Moon Cancer): x -> B+ (Avg Score: 8.22) -

Mysterious Heroine XX (Alter)
Tier B+
From the far reaches of the Servantverse comes Mysterious Heroine XX (Alter), debuting during the latter half of the Summer 2026 event. She is an ST Buster Foreigner who also is an unconventional off-Class Ruler killer. Her NP has a massive 200% supereffective multiplier against Ruler Class Servants, and she also gains further Special ATK bonuses against both Lawful and Good alignments, which are very common in Ruler Servants. Her NP additionally buffs her NP Damage before dealing damage, and then refunds 20% charge afterwards. Her skill kit is generally focused on offense, with Buster / ATK buffs, and Buster Star Gather / Crit Damage / Star Gain / Star Regen buffs, which when combined make her a powerful Buster Crit Servant choice. She also has a somewhat atypical NP charge skill, where she can gain 10% charge for every enemy present on the field, in addition to up to 20% fixed charge. She can also decrease NP gauge for all enemies and buff her own NP Gain. Finally, she has access to hard defense in the form of Invincibility for 2 hits across 3 turns. Overall, MHXXA's kit points her to a unique niche of killing Ruler Servants, although she is still a great Buster Crit option to bring in against general Berserker waves due to her Class.

2[NorseFTX - B+][WhiteRabbit - B+][Rathilal - A]
Hakuno Kishinami (Male)Hakuno Kishinami (Female)Tier A
Hakuno Kishinami is the Welfare Servant, arriving at the end of the Summer 2026 Event. Although they are available in both Male and Female forms, their kits are effectively identical, so the differences are only in aesthetic. Hakuno is an AoE Buster Moon Cancer Servant with a very unique utility to essentially convert 10% NP Gauge at a time into 10 Stars. Their first skill notably has a 0 turn cooldown at max level, meaning it can be endlessly reused so long as Hakuno has 10% NP gauge to spare. On each use, Hakuno generates up to 10 Stars and reshuffles Command Cards. This allows Masters to essentially keep rerolling Command Cards (and gain Stars) repeatedly provided charge is available, until the Cards available are more favorable. Hakuno's NP is also unique for being the first NP that is capable of ignoring the Anti-Enforcement Defense effect, which is the defensive buff famously first provided by Altria Caster's NP. It also has a small chance to inflict Stun on all enemies. Hakuno also has a 30% NP charge skill on a 6 turn cooldown at max level, meaning that they are capable of Buster looping with double Koyanskaya and Oberon. Their charge skill also comes with 10 Stars per turn, and the ability to select one of three Special ATK bonus traits: Heaven, Earth, or Human attribute. Finally, their second skill provides a rainbow Card buff and gives each Card color an additional effect when attacking: Quick provides a 1 turn Evade buff to Hakuno, Arts increases Hakuno's NP Gauge by 20%, and Buster increases Hakuno's Crit Damage by 20%. When combined with their first skill, Hakuno can reroll their Command Cards until the desired Card colors are available. Given their status as a welfare, being the first source of Anti-Enforcement Defense and being a decently serviceable Buster Looper and the ability to reshuffle cards multiple times a turn make them a worthwhile addition to the roster.

Tier List Movements
5 Star Servants
Altria Pendragon (Ruler)
Tier D+ > C+
Altria Pendragon (Ruler) gains an upgrade to her third skill during the Summer 2026 Event, which changes the targeting for her ATK buff from just herself to the entire party. Additionally, she gains a 3-turn Buster buff, which helps improve her overall damage output. This buff helps her in her damage output decently, although she would also benefit greatly from an upgrade to her NP proper. Even so, it was generally agreed the upgrade was worth giving her a tier bump.
1Altria Pendragon (Ruler): D+ -> C+ (Avg Score: 7.33) -

4 Star Servants
Archer of Inferno (Saber)
Tier B > B
Archer of Inferno (Saber) gets an NP upgrade during the Summer 2026 Event, providing the standard NP damage buff, while also increasing the turn length of her Arts/Buster buffs from 1 to 3 turns. It also increases the amount of damage inflicted by the Burn effect, which while minor, is still an improvement. The buff allows for her to now stack her offensive buffs progressively as she loops her NP, which in addition to the damage buff, greatly benefit her farming performance overall. However, it was generally agreed this buff was not enough to push her up a tier, and rather keeps her up to date with the current meta.
1Archer of Inferno (Saber): B -> B (Avg Score: 8) - 
2[NorseFTX - B][WhiteRabbit - B][Rathilal - B]
Ishtar (Rider)
Tier B > B+
Ishtar (Rider) gets an upgrade to her third skill, helpfully removing the delayed Stun demerit from the skill. It also now provides up to 30% NP charge immediately, while also increasing the duration of the NP Gain buff from 1 to 3 turns. This helps improve her ease of access to her NP and her overall looping performance, although even with the buffs her NP Gain still remains somewhat low, making her looping still not as smooth as other Quick Rider options. Even so, it was generally agreed that the battery and removed demerit were worth giving her a tier bump.
