The one and only Murloc Pirate Shadowform Mill Priest, as promised, with added wisp for bonus power and synergy.
The key is to get Shadowform out as early as possible to protect your Murlocs and Pirates while you build up to the fantastic Blingtron-Greenskin-Gorehowl wombo-combo. Fool proof!
And if that does't quite finish them off use summon the malevolent Old Murk-Eye to smash them off the face of the Earth. (They can't be on more than 2 or 3 health by this point)
This will get you Rank 1 Legend guaranteed - no catches - in any region, yes even Asia.
Recently went 1000-0 in ranked and also won Blizzcon 2014, but they were too embarrassed to admit they'd been thrashed by my Murloc-Pirate-Shadowform-Mill-Priest.
Good luck and remember to spend all your dust/money on this deck; it will be worth it.
