I've been using this Control Shaman for a couple months now, modifying just a few cards to adjust for changes in the meta. Generally have very good win rates against most N'Zoth decks and aggro decks. Love pulling an opponents N'Zoth with Hecklebot and dropping a Plague of Murlocs against Resurrect Priest. Also handle Aggro really well provided I can get enough of my board clears in hand. The biggest thing I struggle against is, of course, OTK's that I can't disrupt and heavy burn from spells. Don't have a lot of heal in the deck besides the Walking Fountains and Zilliax. Generally, my focus has been on keeping the board clear and preventing my opponent from gaining any real traction. Maybe someone more experienced can get better results or refine the deck more, but I've done better with this deck than any other for quite some time.
