Yeah, and the only way of getting her drops is.... we got easy, honestly, which is great because five-seven is kinda nuts :v
the cores suck, but the power? the power is worth it.

The newest event is some strange snazzy bingo card thing. I will point out that after you get all the achievements possible (by week 2 usually) Continue accumulating key cards. At the end of the event the cards get converted to calibration tickets, which you would have been using during the course of the event. Excellent way to replenish your stock I feel.
Chaore:
Yeah, It's weird and really dependent on luck, but hey, it's pretty easy and chill.
Also, save points until you have enough to clear the rest of the board. Spending before hand just makes key cards less useful, and points don't turn into anything if you have any left :v
