Half Skeelz. Buy Caelus Cr with real money (credit), to support the game and cuz he worth it.
One Leader, Ambre or Hugo or Leader you want.
3 Nightmares: Kolos, Ghumbo, Oshitsune
Good luck, have fun!
Try this Deck: Ambre, Caelus Cr, Tomas, Jay, Michael, Kolos, Ghumbo, Oshitsune
Or, if you want something not-so-deathmatchey with those clans, Redra, Belgosi, Chiara, Praxie; Phyllis, Edwin, Glorg and Pan. For example, since Skeelz have nearly a dozen good 3*s to choose from, and Nighmare has good 2 and 4 stars if there would be something more fitting to your playstyle.
