In my opinion this is the Best Shaman Deck Nov 16 Season 32 to start the season with. Shaman is the strongest class right now so you shouldn’t have too much difficulty climbing the ladder with this list.
There are some decks that counter the list pretty hard, like Freeze Mage and Control Warrior, but you don’t see many of those at the beginning of the month as they are slow to climb with.
You can easily tech a few cards around and still have a strong list. Ragnaros and Barnes are fine, and if you don’t have Harrison Jones a Swamp Ooze is even better in some instances.
