Here it is:
Nistarok, Glorg, Azgroth, Pan, Sargh, Mawpin, Sheitane, Eadh
What do you think? What should I switch?
Nistarok seems to be the weakest link imho,
because he is a 5* with only 5 damage and his damage reduction has a very high minimum, but he is in general a very good and flexible card... so I'm not really sure.
this (not my preset, sadly ) is a very nice example of Nightmares and it also fixes the damage reduction problem they have nicely by adding Uranus as a splash: preset=1386711 [http://www.urban-rivals.com/presets/?id_preset=1386711&list]
