Yes yes, we all know Shaman is in a tough spot and the buffs did little to alleviate that. But that didn't stop me from trying to find the Unicorn Shaman that's been flying under the radar. I've had fair success (low sample size of 24 matches, admittedly) with the following list:
Lost most of my games vs Paladins and Priests, but this deck absolutely wrecks Mages (currently 6-0) and is favored vs Warlocks too (5 - 2). If you're looking for something that ruins Jaina's and Gul'Dan's day, give this list a try! Instructor is optional (possibly even a placeholder), but I'm quite pleased with the rest of the deck. If you're on a budget, you might consider trying Unbound Elementals (haven't tried them myself) and another Wandmaker instead.
If you can think of ways to improve the list, let me know.
After some further tweaking, I've decided to drop Claw Machines entirely and picked up the ye olde Rockbiter + Doomhammer for added burst. This makes the deck less board reliant, and adds more Notetaker synergy. I also added another Cagematch Custodian. Even with just three weapons, the early game curving is too important to pass up.
I've been climbing steadily (I play few hours a day), this deck is absolutely punishing for mages and warlocks. Thanks to early tempo, it also feels decent against paladins too (Devolving Missiles, Arid Stormers and Whack-a-Gnolls being MVPs). After 40-ish games, my winrate is still hovering above 70%. This is going much better than I anticipated!
