Introduction:
This is a tribute to those damned murlocs. Murlockin' has evolved over my time as a player, and it's one of my favorite decks to play. Sure it's not perfect, but it's what we're workin' with! 

Play Style:
Try to play anything but Murloc's for the first few turns so the opponent doesn't know you've got an army of them waiting. Early game pressure and board control is key, if you start to loose board control things can start to get out of hand quickly. Try to keep up some card advantage using your hero power.  Play with an aggressive reserve!

Keep up the tempo, this deck works best when you have board control. Leeroy Jenkins tends to be used mid to late game just to keep the pressure up. Lord Jaraxxus & Ragnaros the Firelord help late game where the deck can start to falter if the murloc army has stalled out.

Synergy:

• Sense Demons - Bring up two random demons, you only have two. Say hello to Jaraxxus & Voidwalker
• Faceless Manipulator - It's a fun wildcard. Copying Old Murkeye or Leeroy if you get to turn 9.
• Alarm-o-Bot - It's good for pulling off heat from Murloc's and forcing your opponent to deal with it in fear of what horror it might unleash. Can be a bit of a wild-card. Nice when it does bring out Leeroy after dumping your hand.
  
• Murloc + Murloc(duh) - Knowing when to play one of your little monsters is key to gaining the most from them.
