Since Warlock has been considered the bottom tier of the classes I Decided to experiment with Murloc Zoo. Since Paladin has had success with it, I figured warlock would also have some success with it since Life Tap is so good.

The STAR of the deck is SEADEVIL STINGER. I tend to keep in my mulligan if I go second with coin, especially if I can combo it with Murloc Warleader, Coldlight Seer or Finja, the Flying Star. The Tempo alone can win some games. It's a cheap way to play more murlocs and flood the board faster.  You can also keep Seadevil Stinger as a refill to quickly flood the board again after a board clear as well. Especially if you can combo with Gentle Megasaur on turn 8 or later. 

The rest of the deck is What I consider regular zoo cards. Devilsaur egg is a good card against control decks that need to use AOE to clear you. Ravenous Pterrordax and Gentle Megasaur can also give you additional death rattles with adapt.  

The Deck has been effective for me so far but is still experimental. Cards I might consider cutting are

• knife juggler and Murloc tide hunter. They can be too slow to get value if you keep them in hand but also don't impact the board much early on. Some matches I've just straight out lost because they didn't stick to the board on turn 2. Although Knife juggler can get some pretty good value when combo with Seadevil Stinger plus Murlocs OR Adapt into living spores.  Although I'm not sure what to replace them with. 
• Defender of Argus is a card I might cut 1 copy of. It's a win more card if you can stick minions on the board and a Devilsaur Egg activator but you already have Pterrordax as an activator. 

Cards you might want to consider

• Corrupted Seer is an interesting anti-aggro card and can be a combo with Seadevil Stinger on turn 4. Especially when either doesn't receive damage from the card or don't mind it (ie Devilsaur Egg) but the prevalence of Murloc Paladin makes this card a potential deadweight 
• Leeroy v Doomguard, the age old debate. This deck heavily relies on the Murloc synergy. Any loss of synergy can cripple your game plan more often then a regular Non-Murlocc zoo deck so Leeroy is preferred but if you are on a budget Doomguard can make an ok substitute
• Abusive Sargent (the pros and cons are obvious)

I'm open to advice on deck changes 

Have Fun
