Yeah i know what you mean.

Crit Teams are my favourite archetype. Even Girls who aren't Crit Girls themselves can get massive damage boosts (Maple ;D)

I am in the same boat as you.

I already planed three of my teams: Crit, Kerria Debuff and Counter but i still don't know what my last team will be.

I thought about:
1. First Turn Weakness Damage with Sleepy-chan, Burning Bush, oppai loli etc.
2. Skill Damage featuring Maple
3. Evasion Team cause i have got Foxy-chan and Iono.
4. Re-act
5. Maybe Solar Blast?

Also Protea is n1 looking. And she uses a Waterstyle attack. i like the visuals of Water-animated attacks

I could promote a low rarity girl ( i have 900 crystals) but i don't dare cause i could miss an awesome promotion from a future girl...
