Took this list to masters the day after the ETS, the ladder was filled with a lot of (argenport) midrange decks and a low presence of Harsh Rule. I subbed in two Flamestoker instead of two Kaleb, Uncrowned Prince that I ran last month (https://eternalwarcry.com/decks/details/f4UA27cNb3w/5th-master-combustion-ramp) due to some great results I had with the card against argenport control which seems to pop up a bit more.
The deck can block ground units forever and with the combination of Devour, Quarry and Stonescar Scrapper grinding out these games works pretty well.
