I tried this deck earlier this week and it didn't work too well for me. Its weaknesses are bad match ups (Roots, All- Stars, Junta and sadly Berserk), and also a little light on damage (especially since no DR). It doesn't damage enough to 2HKO vs 14 life... that has hurt GHEIST a lot. I think Methane has to be included somehow.
Even more sadly, Skeelz wasn't even a factor this week as Chiara was banhammered.
I don't think such low poison as dolly has can really hurt the enemy when you have no dr's in your deck, and it's only 8 life gap, first round doesn't proc the damage in, and that's IF you win in the first round with her and IF the opponent doesn't have Gheist/Roots.
One more thing, isn't Toro banned this week? So maybe Toro to Methane and not sure what else to change Dolly.
