Meh Astrid. Even if she 2hitKos, Leviatonn is a much better choice.
Uppers GHEIST, I'd recommend:
Dolly is an often overlooked 3* for the clan, she's absolutely fantastic and her 7 power really does make a difference compared to Astrid's 6. Too many 8 power and power reducers for 6 power with no kind of manipulation of their own to be effective.
