As you can see, the list is pretty standard and i especially recommand it for higher rank, since people are more enclined to play slower decks ;) The deck is teched to do well against Aggro decks as there is many Zoo but you can try your own iterations for a slower and more late game oriented version.
Due to the Animal Hunter being everywhere making the meta 80%+ aggro now. I run the exact same list but had to cut a two legendary and face for some defense in the form of 2x Senjin and 1x Argent Defender.
It is pretty solid, need to be tweaked a little to adjust to the aggro meta I guess. I recommand cutting off Sylvanas and Ysera for a Wild Pyromancer and either a Cleave or a Sen'jin Shieldmasta. I guess it's up to you to find the right equilibrium to counter what you face the most ;) Faceless is also optional (swap it out for a second Shieldmasta or Argus maybe), but remember those cards are doing pretty well against control decks so you really need to adjust according to the "ladder's mood"
I don't know which legendaries you are lacking but if it is one of those, you can pretty much wait for them ;) Else, you need them to finish the deck as they all bring their form of utility
I dont have sylvanas or baron or alex yet. In the meantime what do you think those 3 slots should be? I was thinking maybe an ooze for weapons and then 2 shield mastas for the aggro matchup? Maybe a second gorehowl? Thanks.
