I am using a Nightmare/GHEIST combo right now and it is not taking me very far. It could be that I haven't played for a long time, but any suggestions that might help me refine the deck would be appreciated.
Toro is banned in ELO this week or I would have him there.
Krash's New Elo Rescue
That should easily get you to 1300 on weeks that Sledge isn't banned.
Bluff and Double Bluff
Not exactly a mainstream deck but it works very well with 4 eight-powered cards.
Mathwiz's deck is propably the best choice for low budget... Nightmare/GHEIST is really effective combo, but Kenny isnt that good in elo anymore, there are too much cards that counters him nowadays... Nightmare has to be refreshed a little bit also Draheera isnt good in half deck, Toro would be great but he is banned this week... with mono Nightmare, I'm using mono in this week, my deck is prety similar to Yours, but I use Glorg over Kenny and Eadh over Sheitane... she could be a good bluff, maybe I'll consider putting her over Eadh too xD also I was using Uranus over Sargh, dr is useful sometimes, but with that much GHEIST and Roots in elo, he usually is just a wasted space
