Used up more SCs than I would've hoped (10 from the event missions 8 from 4 stars and 2 saved from stamp card) but I got everything done, mincosted Echidna/Aria and Anya with 80 MCs to store for the next set. Have 8 SCs left and another 12 4 star missions to complete..I have no decently lvled Silvers so some are pretty much impossible right now.
