Since everyone was posting their teams, this is my current setup.

Just this last week I was playing around with different 5* knight combinations to try something else. I had both T3/4 run skill activation before, but now I changed it around a bit to lets other girls have some fun as well. Optimal ? Maybe not, but meh.
T1 - Main Crit team
T2 - Evade team in progress (Soapworth and the 5* will be replaced with evasion girls as time goes on)
T3 - 5* Crit team.
T4 - 5* Counter team

So many of my Blunt type girls have Crit, that you could build one more squad of them with not problems. Funny enough almost none of my Slash types have crit so far (maybe some will after blooming).

So far I am not extra impressed with T3, but since I wanna give them a spin I dont mind. After that I think I try for a re-action team, as in girls who have a chance to act again before the turn ends. I have few of those though not sure if at least 1 of each color, so atm I am not sure if I could build a full team of those. But it would be interesting to see since I used few of them individually and the chance to act again is not that bad at all. Times 5 it could be some nice extra damage.
