Pic related are some decent to good dolls to use on this mode that F2Ps should have some level of access to. I highly recommend borrowing a whale's Makiatto as she trivializes this mode pretty hard. Even a V1 Maki will do if your support list doesn't have a whale. The selling point of V1 Maki is she will typically kill 3 enemies every turn since her S1 negates the debuff and her interceptions deal full damage after. A V6 Makiatto has extra interceptions so she'll kill even more enemies per turn.
