Idk if you meant to post a preset.. But a Deck I used once was:
Bristone Arkn Astrid Rolph
Nellie Oxen Wendel Rubie

Lots of 2hko's, even more if Bristone is Furied.
Possible swap Rolph to Anibal and Rubie to Beetenka and still keep the 6 Dmg

Meh Astrid. Even if she 2hitKos, Leviatonn is a much better choice.

Uppers GHEIST, I'd recommend:

Uppers
Dorian 5*
Nellie 4*
Oxen 3*
Wendel 2*
Total 14*

GHEIST
Bristone 3*
Leviatonn 3*
Dolly 3*
Arkn 2*
Total 11*

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.
