For those wanting help against murlocs!

Run a minion heavy rogue deck. It straight up counters murlocs. I think my rogue deck wins 9 out of 10 times against murlocs. Basically, the rogues hero power is REALLY good in the early game and it has combos such as backstab SI7 yada yada.

Murlocs are currently non-existent in rank 4 so yeah.
