This season I was actually really struggling reaching master, since the meta is kind of all over the place. From Mono Red Aggro, Grenadins, Valks, to Kruellysian, TJS Control and Sling decks. So this is the list that finally took me to (top 80) master.
Noteable mentions - I cut the justice heavy part from the deck as I was too often struggling with the influence (for either
Ijin, Walking Armory or
Rolant, Iron Tyrant) and I moved
Know Thy Enemy to the market. I also added
Seek Power for better influence fixing and the powerbase feels pretty solid now. The replacement cards were
Rust Grafter,
Reappropriator and
Suffocate.
Rust Grafter gives us great market access and is a Valkyrie on top. It can just grab
Metalfang, which has actually won me a considerable amount of games, as it often is one of the few cards that really helps against
The Speaking Circle.
Reappropriator is a great meta call and is not only great against decks that play relics, but also against decks that rely on dealing damage to kill stuff (with spells or weapons) so it's actually really good in the mirror. Just be aware against Autoread.
I initially played
Suffocate in the market, but I was fetching it so often that I decided to main deck it and think this was a great descision.
Dichro's Ruin is the killer against Sling, but it can also be great against control decks that draw tons of cards. It also has the nice side effect that it gives you something to fetch when you steal a
Coveted Gemstone with
Reappropriator.
Edit: after some feedback I added maindeck
Dichro's Technique it's great against circle and damage based decks (e.g. Kenna).
