29 Pulls away from the guarantee. Do I keep going? Or should I save for the up-coming girls?

I did pull Yixuan and her Signature. For stunners I already have Koleda-Lycaon-Trigger-Qingyi, but it honestly feels liek Trigger is the only that counts now.

I think Ju-fufu could be a good addition, and she could also work great with Evelyn right?
