I found this to be a reliable deck (for my play style):
Bonnie Ld 2* / Tula 2* (I prefer Bonnie in this case)
Ulrich 3* (however, Tyd and Ector are very viable as well)
Sting 4* (good pillz saver, I prefer her over Scubb, but Scubb is ok as well)
Selma 5* (surprised she got only mentioned twice so far)
I honestly don't know how Ahkab will do in the current ELO environment. It is all about nukes and you really don't want to trigger his defeat ability because that means you miss out on 8 damage and you potentially take a huge hit while doing that. After that you are left with mostly low damage cards and even taking home 3 rounds may not be enough to win.
