EDIT: I changed up the deck to be more aggressive because I felt like that would improve more matchups. It is now a face hunter instead of a midrange hunter.

^^My past 11 games with the deck. The only loss was to a murloc paladin. 

Hey guys, I was able to climb from rank 16 to rank 4 real fast with this Murloc Face Hunter. It is cheap and doesn't require any cards from Kharazan or other adventures. It is a traditional midrange hunter with the murloc package of Murloc Warleader, Bluegill Warrior, and Finja, the Flying Star. Hope you enjoy the deck!

Mulligan:

(Will be updated for each hero later): Keep finja unless you have no low drops, and throw away all other murlocs.

Look for low drops such as Dire Mole and Alleycat. Crackling Razormaw should be kept with one of the one drops. You can keep 3 drops like Animal Companion and Bearshark if you have the coin, and dire wolf alpha if you have the coin + Crackling Razormaw.

Tips:

 Try to keep Bluegill Warrior in your hand if you draw it. Wait until you get a Murloc Warleader for maximum value. 

Matchups: 

Mage: 50/50 Matchup. If he gets a good start, you can lose very quickly. If you manage to stabilize the board with a decent amount of hp, you will most likely win. Watch out for Pyroblast(from Primordial Glyph) Fireball Firelands PortalandFrostbolt. Eaglehorn Bow can be very good because all of secret mage's minions have 3 or less health except the 5/5 Kabal Crystal Runner. Exodia Mage is pretty much a free win unless they get an insane hand because of how fast you can kill them. 

Hunter: 50/50. Most hunters are big spell hunters with secrets. This is a very hard matchup, but thankfully there aren't many on ladder. Watch for Explosive Trap and Wandering Monster and Deathstalker Rexxar. Other matchups depend on the hands of both players. 

Paladin: 60/40. Murloc paladin matchup depends on whether or not he gets a good hand, and whether he gets Righteous Protector. Watch for Righteous Protector and Call to Arms. I have had great success beating them. 

Rogue: 60/40. Kingsbane Rogue and Quest Rogue are easy matchups. He has to use his face to clear minions, and you will kill him fast. They have to get lucky with a huge edwin vancleef to win.

Warrior: ?/?. I have only played 1 or 2 warriors so far. Watch for Whirlwind effects and drywhisker armorer and Sleep with the Fishes. They can stack lots of armor in one turn so don't waste your spells unless you know you will kill him.

Shaman: 55/45. If he doesn't get Volcano, Lightning Storm, or Healing Rain, you will most likely win. Watch out for Volcano when playing Bittertide Hydra. Some run cards like Devolve and Drakkari Defender which can be problematic. Make sure not to put all your buffs onto one card because of hex.

Druid: 60/40. Pretty easy matchup. Play around Spreading Plague and Swipe. You do too much damage for him to handle. You can ignore Jade Golem if they aren't going to kill something important like a Leokk buffing 5 minions. 

Warlock: 50/50. Warlocks aren't that big of a deal unless they get out an early Voidlord [/card]or have a saving [card]dark pact. However, they have a lot of heals so it is not an easy matchup. Try to SMOrc him down but kill Mistress of Mixtures if it won't heal him the full 4 hp. Lesser Amythest Spellstone is a large problem if it gets to 5 or 7 damage. If you control the board against zoo you will win, but if he gets a strong start with Voidwalker, Flame Imp, and Kobold Librarian things can go bad really fast.

Priest: 55/45. A good matchup. If you play around Duskbreakerand he doesn't have Greater Healing Potion, you are good to go. However, big priest can be a hard matchup if they get an early Obsidian Statue. Also watch for Potion of Madness and Divine Spirit Inner Fire Combo. 

Good luck on your climb to legend!
