It is awful to Anyfin OTK. Could be of some help to Murloc Shaman, but there are some midrange-ish lists already and they cant keep up with the current meta. Lets hope we see some more Murlocs this expansion.
This is the type of murloc you want to pull out Finja, the Flying Star. If we can some more deathrattle/on board murloc effects then we might eventually have a new murloc archetype. Right now murlocs are mostly feature Battlecry though.
