I have been struggling to reach masters this month, every deck I tried (greed pile, praxis ramp, maul) were just getting wrecked on the ladder and i felt the greed pile and praxis ramp were a just to slow.
I was coming across of really aggresive stonescar decks and after seeing joey's post on warcry (https://eternalwarcry.com/decks/d/UD-9aApUs5I/stonescar-aggro-top-25-throne) I thought I would try his deck out.
I had some issues while piloting the orignal stoescar deck Joey posted, I was not happy with the power base, i felt the inclusions of crests and the high numbers of banners and seats meant that too much of your land was comming in depleated and as such really slowed the whole deck down.
I took joey's deck apart and re-built from the ground up yesterday and it took me from G1 to masters in a couple of hours.
I am not too sure on the market at the moment, I added the karvet and dizo's office for the late game in case they were needed, but I have never had to use them as generally the games are done pretty quickly.
I oculd definitely see some card changes being made to this so if anyone has any questions I will do my best to answer them.
I hope this can help
