Notable Bond CE's?

I don't know a lot of them but here are a few I'm trying to get plus some that I took note of for being different than normal.

Tamamo (Caster) and Nero Bride- 15% Arts boost to the whole party. Since Tamamo's the main Art-type support, it works well for helping build NP while also increasing damage. For Bride, it gives her a passive perma-buff that she otherwise can't give by herself.

Altria Saber Alter - NP Strength +30% and 30% chance to give a 5% Def Debuff with each normal attack. (Pretty much like the challenge quest)

VladIII (Berserker) and Kintoki (Berserker) - NP Strength +30% and 30% chance to get 5% NP charge per normal attack (RNG reliant but may be a good way to charge his NP faster.)

EMIYA - NP Strength +30% and 30% chance to get 5 crit stars per normal attack

Arash - Remove all Debuffs and restore HP of all allies by 5,000 when defeated (Given his suicidal NP, it's worth noting but since he is usually used to farm... it depends I guess)

Gilgamesh - NP Strength +30% and 30% chance to get 10% crit damage buff per normal attack (Useful due to his buster crit style)

Cu Alter - NP Strength +30% and one-time Guts (20% health)

Georgios - When defeated in battle, apply Invincible (1 time) & Damage Cut 1000 (3 turns) to all allies (As one of the hardier tanks, this adds to his usefulness if he did get killed)

Jack - Increase Critical Strength of all allies by 25% while she's on the field (With all the crit stars she generates, her Bond CE synergizes well to make use of them)

Martha (Rider), Medea Lily, and Irisviel - Increase HP Recovery received by all allies by 30%

Here's the site page if you wanna look up more.

Melts is pretty good, 20% quick and 30% crit dmg for herself with 10% crit demerit for allies.

The latest released servants on jp has some nifty bond CE.
Murasaki's might be niche but a permanent 20% attack for demonic enemies paired with her skill set will be useful if she is used as support.

But... Kingprotea is unexpectedly above normal values for the CE.
A base 20% buster increase for her plus another 20% if her first skill is active. And since it will have 100% upkeep except if she gets cleansed or she uses her second skill it means a 40% Buster buff with a slight Quick demerit for the party.
Her NP is buster and she can do a NP-B-B chain so it meshes extremely well with her kit.
