Well considering the rest of the Girls are Purslane, Nightmaher and Saffron, there is not really that many to choose from.

Saf and Night both have counter attack, which is nice on paper - if I dodge I win, if they hit I win coz they take damage !
...but if you think about it - going with counter team, you dont want evade since you WANT the enemy to kill themselves on your team when attacking.
I think girls who have defense buffs, or self heal to go with the counter (like Soapworth) work better for that matter.

Thus if it leaves only Purslane who can heal herself up, and has evade. Again sounds good, but then I think in the terms of:
4x Skill act + Kerria vs 3x Skill act + Kerria

I think the little Peony while not as amazing is still farily relevant due to her Skill act.

Honestly Skill activation passive is so good, it makes a shitty girl relevant. Look at Dogwood. She was absolutely crap before in anything other than a Solar Blast team (though she could be absolutely amazing if put into one). The skill up made her "usable" for such teams, offering something else than just the stats of a 6* and mildly buffed SB, especially if you are low on 6*.

With that logic, the Skill act makes Peony worthile if you have a strong nuker to finish up your team combo.

Though Peony is still good even by herself, dont get me wrong. As I wrote back in one of my posts - its absolutely feasable to do 2 fully functional Crit. Teams should one choose to go that way

Would be nice to have two or three more Evade girls, at least two of which would be Blunt type, and the last one Pierce or Magic (Red Spider Lily is the prime Magic Evasion choice, Golden lace is not bad, especially if you can stack that Attack Reduction with some other girls, but the Skill act. of Spider Lily .... yeah, I talked about that already ), since I really dont like Pumpkins art style heh >__<
