The key is late game with Jade Idol and the auctioneer and if you can Fandral. But also make him over draw is a very strong key against all control decks. I run starfall because is a great board cleaner against aggro and big minions if you match it with Fandral.
You can also run Yogg instead of Kun or starfall but I’ve been better with those
Why not run Malygos ?
I haven’t crafted Malygos yet maybe that’s why. But I just go 19 to 10 with this list
