They aren't flashy or anything, but they are quite useful.
Yeah I didnt use Maost. Regret faust is so high because of Everlasting nukes, I was consistently lucky with her speed.
Gregor is nice for finishing off stragglers and avoid taking a turn just to kill them, also I saw some clutch staggers with his auto skill
Ish is good and it's fun to play her matching the colors minigame.

It's not a crazy walpipi or anything, but I'm satisfied with the performance and fun value.
