I've always been huge fan of Evolve shaman and really tried to make Mistcaller work for the last 4-5 expansions. I believe I've finally made a deck that is worthy of showing.
So far I've won against lots of different deck types. I really belive its over 60% win rate, I hardly play so I cant get thoose true numbers.
This deck has 3-4 win conditions I guess.
First is the Evolve part, but there is also major buffing minions imagine kele +1,1 mist +1,1 with bran that works with both could make it +4+4 on all minions.
Then we have the shudderwreck, if none of the above work you still have that shudder he should give you almost a full board with 8/8's.
Then last we have the Brann+Coldlight so mill the shit out of low hp / low card deck.
