Here's my advice: ditch SI:7 Agents. How many of you just sit there with these in your hand, unable to use the combo effect unless you burn the Coin or something? They slow an already slow deck down and don't do anything to help. Go with direct damage like Shadow Strike, which does 3 more damage and you can use it sooner. Also removing both Cults and Shadowcaster was IMO a mistake. Add 1 of each back, add Arcanosmith so you have something else to use with Brann (throwing out 2x 0/5 taunts is a great way to buy 2 turns and get Brann on the board relatively safe from harm).

buy all the expansions, there are so many cards there that are essential to many decks.

Why no reno?

While yes, it can almost confirm your win during late game, it just doesn't match the deck at all. Gang Up has absolutely horrible synergy with Reno. The reason why it's almost impossible to use Reno effectively is because theres already an insane amount of crucial duplicate cards, and Gang Up will only end up creating even more duplicates. Meaning this would end up with you also having to be in fatigue for it to be of any use. And at that point in the game your opponent should be dead, or about to be. If you're scared of losing during late game, you can always use Violet Illusionist to secure the win as well. It has much better synergy and worth, and can also replace the legendaries in this deck, like Mukla or Thalnos.

Can confirm that violet illusionist is a good sub, and might deserve a place over one of the main deck cards. It absolutely saved my life in a match today. 

I've been playing around with this but am failing to understand why Dirty Rat is in this deck. It has done nothing of worth for me. Deathlord existed to pull minions out of the deck faster so you could mill them. Dirty Rat is pretty much doing the opposite of what you want in my opinion. I think Doomsayer is far more effective (especially after a Vanish).

Agreed.

Adding Dirty Rat was actually a mistake, I thought it had the same deathrattle as Deathlord. I was so sure that the card was going to be good for the deck I changed it without trying it out, and then soon after like 3 games I realized how horrible it was, but I was too lazy to update the guide. I've been playing around with different archetypes again and I'm probably just going to stick to good ol' Doomsayer, which was my original intent for the deck this in this expansions meta. Sorry about that.

What are you toughts on arcanosmith?

Hmm.. In general would say it's more of a card you'd see in arena and not in constructed. Though if your decks are on a tight budget you may think you could use it; but most budget decks would just use Sen'jin Shieldmasta.

Think of it like this:

Would you rather have a taunt that can trade at all times or just a 0/5 wall with its damage split into a 3/2 token. Plus, when the 3/2 dies you just have a 0/5 body with no benefits. If it were a 3/2 that summoned an 0/7 it might've been able to see some play.

Conclusion: Dust it.

 This list needs to use counterfeit coin, mistress of mixtures, shadow strike, and reno.

"Mistress of Mixtures can be swapped for Refreshment Vendor as well, if you prefer to get early heals off." 

And Counterfeit Coin? Never. It only provides tempo and the last thing a mill deck looks for is tempo.

If you're missing a prep it works as a decent replacement.

fun deck! any replacements for King Mukla?

Yes. Doomsayer is a great sub that I would maybe use over Thalnos and Mukla. Pretty much anything that is can stall early is great.

Fon? Did you mean FoK? Fan of Knives?

It's okay to sub poison, because you want to try your best to maintain as much health as possible, but Fan of Knives is sometimes slow.

By the way, Dirty Rat is actually an extremely good card for this deck! I almost didn't see that card in the latest expansion, thanks for pointing that card out. I'll actually change up the deck now!

Hi Coty, thanks for the update.  For a long time I was playing with a N'Zoth package, with Belchers, Deathlords and Swords.  Thinking that Mill needs another closer against Jade Idol decks, I have since switched to a 5 card C'Thun package... 2x Disciple, Twin Emperor, C'Thun and Dagger of C'Thun.  It still can run a regular Mill game, but can also do heavy, heavy control with Shadowstepping C'Thun and then ganging him up.  It adds a new dimension and synergy and I'm really loving it.

I have been playing a modified version of this deck since Violet Illusionist was released yesterday. I run two of them: one for my early game to smash minions without taking damage, and one I keep in-hand for the final mill at the end of the game to guarantee that I take no damage if I also go into fatigue. Very, very effective.

Mill Rogue is probably one of the hardest decks to play and the games can go for too long sometimes, but boy is it satisfying when you beat those Legend card back players.

Thanks Coty!

Tried out the Curator, it's nuts.  A taunt that draws a Coldlight?  It's a mill dream come true, and I think it's going to be a core card in this deck.

Curator seems especially useful in Mill decks that run Azure Drake. I might drop an Arcanosmith which I was using to stall and put in The Curator instead, pretty cool idea. Curator is more mana but might be efficient for stalling or preventing some face damage later in the game, while also being almost guaranteed to draw a Coldlight and possibly an Azure Drake as well.
