Did the 100/2 map twice and the 40/4 map twice as well so didn't have stamina to get the 27 stars from 3*ing the final map. Wouldn't have needed to do the 40/4 map twice if i had not missed that one ninja rushing top at the very end. Had not placed any blocker there...
Edit:
Well i guess i decided to do 3 premium summons for the stamp card and ended up with a Deine and Rino. I was lacking a good second tank so i guess she's welcome, but it's still a random disappointment to get her instead of all the tons of blacks that also exist.
