An updated version of my previous Stonescar deck (https://eternalwarcry.com/decks/d/S4HwKnS0bWM/rank-2-fast-stonescar-aggro). Since Hellion has been nerfed, I've reduced the number of copies in the deck to 2 and also removed Vara's Favor since we are not as concerned about hitting 2S influence now. I added market access instead. I was able to climb quickly from Gold III to Masters with ~80% winrate playing this.
Update for April - This deck once again carried me from Gold III to Masters in just a few hours game time. It's currently sitting at Rank 1. The only change I've made is cutting 1 copy of Midnight Reprieve and replacing it with a standard Fire Sigil to reduce depleted power draws. I've been using every market card except for Repurposed Wares, so I think that can easily be replaced with another card if you want to make a substitution.
Update for 4/24/2024 patch - Both Grove Supplier and Calm Instructor have been nerfed. Calm Instructor has lost Charge which significantly alters the play patterns for this card. I am not updating the deck, but be aware that these nerfs will appreciably reduce its aggro capability.
