Yeah it's really between Pinkladies and Black Locust.

Cypress Vine would be perfect for my Debuff Team but yeah she doesn't fit Waifu Criterias.

Pinkladies i have to get first. Shouldn't be to much of a problem. I only have to wait until her reissue gacha comes around.

If i don't get her i will promote Black Locust cause i always liked her and she reminds me of Esdeath from Akame ga Kill ;D

Together with Christmas Rose (I got her through a lucky pull month prior) she makes it possible to run a Crit Team which always has 80%+ Skill Activation (not only on first turn).

thanks for your input
