Your skill build actually resembles what i use on kagerou so i don't see a problem with it. you can lower your 16th night to level 3 which will make more efficient(60 sec duration, and 60 sec cooldown which makes it easier to keep it up all the time.)
For your stat, I always keep my vip buff for granted, but since you didn't mention about it, please do next time so i could give you more idealistic stat.
My suggestion on stat
You only need total vitality of 100 including your job bonus, so I'd just give 96 base vitality. so with job bonus, you will achieve 100 vit point for stun immunity. I'd give 80 agi so you could get 180 aspd(188 is probably optimal for fastest spam that your finger allow so if that's something you're looking forward to, feel free to adjust it.) I gave 30 dex so that if you need ur hp to be in certain set up, you can just put all those stat to vit to adjust. otherwise, 30 dex should give more matk than 20 something luk.
For the gear, RWC pendant is always the best choice. +3 int 3/3spell for both is always optimal choice. If you can afford ent card, that could be alternative for bryn, but if you have bryn, that works better imo. If you're looking are some cheap alternative, farm kvm point to get glorious suit. other wise, those two are the probably most optimal set up.
Since we have FA wing, you are most likely will have insta cast. 30% from FA wing, 32% from double pendant, and 20% from 4/4 spell bazerald, and 20% from +9 CoD. That is total of 102% variable cast reduc, and since 16th night will remove all your fixed casting on all of your ninja skill, you wont ever need Phen effect.(within provided information with +12 RWC dagger/4/4 bazerald)
KBC card is definately one of the best option for accessory card for pendants. When FA wing gets slot, you can go with Raydric, or Deviling. Thats totally up to you. For the shoes, I personally use Vidar's Boots because its cheap, and give me SP also.
I personally prefer free headgear slot rather than using CoD, so I went with 2x +9 4/4 spell Bazerald, But if you have money, and doesnt care about two headgear slot being used with CoD, you can always go with +12 RWC Knife. Although, Bazerald will still offer more base matk.
