AtaK has been #1 NA for a long time now, briefly losing his place to Kolento for a period of time. But almost immediately taking it back. This is also the deck I have played this season to get to top 10 legend NA, but am now #12 in NA.

About the deck:
The deck is very similar to Miracle Rogue in the sense that it takes advantage of the rogues cheap removal to get value out of the Gadgetzan Auctioneer, but is very different in the sense that the deck not only has board presence, which miracle rogues do not. But also does not solely rely on getting the Gadetzan Auctioneer and can actually without it win that match. Also the deck is reactive and you must interact with your opponent where as in Miracle Rogue you have much much less interaction with your opponent so the rhythm of your game is revolved more around your draws rather than what the opponent does. In this deck that is not the case, you must interact with your opponent and play around things more often.
What's with Malygos (Does it work?)
Malygos is a strong finisher with combos like Malygos + Sinister Strike (8 dmg) + Bladeflurry (6 dmg to all enemy characters). However the strongest part of this finisher is that your opponent has to play around leeroy as soon as they start getting low, so all through the game they will be putting up taunts and playing inefficiently because they are scared of getting leeroy comboed. So, the slow down of them doing that can allow for the game to be long enough for Malygos combos to happen.
General Play Style
The general play style is to control the board and react to your opponents. So for example Coin + SI:7 and just hitting face is unnecessary, in most cases. You want to hold your dagger, and your cards to setup plays where you can control and as you control you will be able to get in little poke damage and draw cards. Almost like a tempo deck.
