Hearthpwn

Here's my take on a highlander control shaman, having a very good time playing this deck at the moment, it got me from bronze to diamond 4 quite easily and I'm still going on a win streak.

The main win condition is to go to the fatigue and smack your opponent with c'thun, and it works quite well. Even if you are playing against a c'thun deck and they throw there c'thun earlier and it doesn't kill you, you just heal back to 30 hp with your witches brew and they usually concede.

Cant really tell what deck is to be scared of except of combo demon hunter, and maybe evolve shaman. but these decks wasn't a big trouble for me at least since nobody knows how to play there combo on dh and evolve shaman is usually just a bit slow early in the game, so you have time to draw whatever cards that will help you (usually most of them).
