Keeper of Souls (My BFF)

As of 4.0 are there any viable KOS teams anymore? I tried a lot listed in this thread, but I have to be doing something wrong. I just can’t get a rhythm down. Currently I’m a fully traited mech wiping the floor in 3 to 5 rounds with my mech team, and it’s hard to find anything comparable mid game ( I don’t have mythics, just about 10 legendaries.) Still wiling to give KOS a try if I can just figure out the play style. Suggestions for KOS teams as of the 4.0 patch?
