If you want to use the Best Shaman Deck August 16 Season 29 ladder climb then is has to be this midrange list. I made it to legend with this exact list.
It has some of the aggro Shaman cards for extra burst, while having those strong late game minions and with double Hex you can make some value plays to keep you in the game vs control decks.
If you’re meeting a lot of aggro decks switch the Stormcrack for another Lightning Bolt, and swap a Mana Tide Totem for a Doomhammer. Shaman is Tier one right now, take advantage and race up the ladder.
