In New Hearthstone’s Year, Shaman lost some very powerful aggro cards as trogg and totem golem. But meta is fast and this aggro deck is still very powerful.
I think, my un’goro update is tier-2 at least. I recommend to use it on tournaments like very powerful aggro deck!
Don’t save Bloodlust – just use it to maximize damage. You have a lot of bolts (6) and 4 weapons to kill the enemy.
