Twenty charms + Woeful Whips will usually win this dungeon unless you have someone not doing that type of deck. The most damaging deck usually will win anyways, because someone will most likely use banes + Bane extenders for it.
Now I don't have Inq equipment so this is my deck *I don't have a full set of Whips anyways* Just take this as an example of what you can use if you aren't an Inq
Rogue Green Death x5
Nightmare Powder x5
Hateful Flame x3
Faked Mercy x3
Death Sentence x2
Grallan's Rancor x1
Persistent Disease x4
Woeful's Whip x2
Instead of the Rogue banes, things like Choatic Decay or more Death Sentences will work out just fine, I only have two whips so thats more banes I had to put in and well..I didn't really have enough good ones to make up twenty banes right now..
