I like to use Skeelz because they can be a great supporting deck due to their bonus. I sometimes only use 3 of them in a half deck so that I would get the other clan's bonus more often. However, their 2* aren't too good. Only one I find usable is Redra, hopefully a good one will come out soon.
I also like La Junta, despite what anybody says. I like their abilities and high damage (mainly due to bonus). I just find that if they were to lose their abilities or bonus, they would be affected quite significantly.
