I'm actually starting to see some serious potential with a few of these cards
So my idea is essentially Aim for the early aggression with your murlocs and then drop hard to deal with issues in the late game.
I think a great starting turn 1-4 would be something like Vilefin+Rockpool Hunter+ Unidentified mallet + a buff card or call to arms. It keeps everything pretty strong early game. Turn 5 really has nothing unless you want to weave in some off mana plays but the big bomb play is turn 6. Stand against Darkness + Crystal lion can both be played on turn 6 for 5 1/1s and a 5/5 with divine shield meanin 10/10 in stats on turn 6 for basically nothing.
Ontop of that you have the standards like spike ridge and such. I want to try playing with primal fin champion because of Lynessa which is why i have a few extra buffs right now. Tentatively depending on how the deck flows i might cut silvermoon portal and primal fins for other tools.
As an added bonus you can still use the stand against darkness with your unidentified and hope you land divine shields
Generally it would be over priced by 1 Mana Max and chances are you just wouldn't use it and just use a spike ridge or literally anything else. It's a tempo swing card which midrange decks like. If it happens it's insane if it doesn't who cares. Murloc will win most of the time by turn 6 anyways, this is a come back for when your opponent wipes your murloc board and won't have an answer for the following turn.
Think of it like blood bloom for warlock. If you can turn 1 or 2 out a 5 Mana spell it's hard to come back from. Well if you pop out a. 10/10 field in stat after a board wipe, it's hard to come back from
