Hello, I'm Neonpig, player from NA and I'm bringing to you my version of the mill rogue,
I built this deck right after finishing BRM's first wing today earlier, and for a deck just made it went pretty good, thought it is still gonna have more playtesting.
But enough blattering, let's go to what matters:
The main strategy of the deck as the name suggests is decking out your opponent, and usually winning by fatigue, and the concept around this is pretty simple: Have more cards in your deck than your opponent. That's why Gang Up is such an important card, because it literally increases your deck size by 3
The way to play it is the the of playing a control deck, as you should think of all possibilities and always be far ahead planing your turn, sometimes you even ein with a right dagger to face and Coldlight Oracle to give fatigue damage and opponent goes to exaclty 0 the next turn, you'd be surprised the many times this happens
as you would almost always want to cast Gang Up on your oracle, this will provide you insane amounts of mill while managing to keep your deck bigger than your opponent's (fact: in many games using gang up on the murloc i ended up with up to 10 cards while opp was already on fatigue)
you can also oracle + shadowstep + oracle for 4 mana, and that is also very efficient
shadowstep can be used to trigger Ancient Healbot a second time if you are that much weary of life.
Vanish when your opponent has a full hand is a great board clear. Not to mention that you get to trigger your battlecries again. Or even if your opp has not a full hand, you can use it to gain tempo and fill opponents hand for programmed mill, works very well.
Sap is a targeted removal, and for some reasons is a cheaper vanish, being also able to be a minion-kill when opp at full hand
now for the other cards: Dancing Swords and Deathlord are staples on mill decks, and is not for coincidence, both are very good, they decrease opponent's deck size while being somewhat threats for their coasts. Sludge Belcher is that extra line of defense so required nowadays. Big Game Hunter, a backup plan if you fail to keep board presence against strong targets, Emperor Thaurissan is just sick, he just got here and is already the best drop 6 i can imagine, works extraordinarily great in any situation.
And then there are the control tools, the ones that really give you board control, besides the control-mill sap and vanish, there is also: Assassinate, Backstab, and Eviscerate (that can also be a finisher)
hope you like it :)
