This is the list i used to get rank 5 this season, great early game and arguably even better late game with skelemancer/ steed or bonemare combo. 

Always muligan for your 1 drops, if you can get a rockpool hunter in your opening hand as well as a 1 drop then your early game is already gonna be on top, if you have rockpool hunter and a 2 cost murloc then use your coin for max value. 

Against control/ midrange: don't be scared to drop your friendly megasaur on turn 4 even if theres no murlocs for the sake of tempo, and if you have skelemancer and bonemare or steed then you can afford to lose tempo on turn 5 to regain it on turn 6 or 7, the only counter there is silence effects which i only ever encountered from the razakus priest. skelemancer is also very good against doomsayer, if your board is relatively dead and you have the opportunity to throw your skelemancer into a doomsayer- do it!

Against aggro: righteous protector is your best friend, in combination with a Redemption from your hydrologist, this guy can take 4 punches while you build your board up (bye 1 health minions). Rallying blade is now the equivalent of fiery war axe, you want it in the early game to help your board develop while dealing with enemies.

It's a pretty straight forward deck but i'll do specific mulligan guide at 20 likes idk
