Alright, done with the event and already got 3 witches dropped. I'll take a break from farming silvers to farm DC on Thursdays, farm another 8-9 witches just to have them and then see which map I should look at afterwards.
Looking at the remotely possible upcoming units that I actually care about:
Swordmaster Sandra, Priest Warrior Serra, Sailor Leanbell, Witch Eliza, Ninja Nagi... I need to look through storage and see if I have everything in order once they arrive.
Leanbell and Nagi... I already have -2CR Saki and Horace so grabbing more melee ranged units is really pushing things, but I don't see myself attempting to further reduce Saki and having a min-cost black Ninja sounds so damn tempting.. and Nagi has way better art. Leanbell also has really appealing art and this harem army needs to be both stylish and functional to see field time.
