To be honest i was like "dont put only murlocs it doesnt look pro" but honestly, those murlocs are so good, there is 2 dredge, 1 poisonous, multiple rush to take back the board.

I wasn't putting the 5 mana murloc at first place but if we dredge him and put its mana cost for health cost thats insane. 

Cards that may not fit the deck are:

Gorloc Ravager => too expensive

Coldlight Seer => 2 health when your murloc already had +1/+1, +2/+2 or more?

Lushwater Murcenary => no particular effect, seems a bit slow and need to have a turn 1 murloc on board.

Cards that may replace a murloc:

Curse of Agony => dealing some damage. Since murloc try to deal a lot of damage we may lack of direct damage to finish the opponent. Plus murloc fear decks who draw a lot tot find solutions.

Unstable Shadow Blast => a good trade card if we struggle at taking the board (we are not supposed to but maybe it will be the case)

Drain Soul => another trade with lifesteal if there is a lot of aggro decks in ladder

Demonic Assault => deal 3 face damage if we need to finish the game. Plus it can put taunts to protect our murlocs from poisonous or some kind of trade

Sir Finley Mrrgglton => could be played if we need to switch at some point our hero power to one that deals damage like hunter, DH, druid, rogue, etc.

Mr. Smite => finisher if we struggle to end the game.

Battleground Battlemaster => could be a finisher but seems expensive and need to have a board where Mr. Smite is a stand alone.

Changes done:

- 2 Slimescale Diver => on board first turn, can't go face the next turn. Too slow. Plus poisonous is useless if our murlocs have a tons of attack.

- 1 Murloc Tidehunter => I replace it by sir finley to get one more change to get bottom Azsharan Scavenger that give +1+1 to every murlocs

+ 1 Sir Finley, Sea Guide => One more change to get bottom Azsharan Scavenger that give +1+1 to every murlocs

+ 1 Lushwater Scout  => really strong to trade.

+ 1 Lushwater Murcenary => probably better than Murloc Tidehunter. To test.
