Deck I used to push Master in April 2018. Used Elysian Midrange to get most of the way there, but it's winrate dropped and the deck was not feeling super fun so I decide to jump from the most linear deck possible to something totally different. Deck had a 60-65% winrate up through D1 and at least 55%+ in M300ish through the end of the month.
Kaleb is a fun of that doesn't get cast very often and is usually very good when he does. The singleton Into the Furnace has proven good but not exceptional. Combustion Cell as a two of has been extremely good, and sometimes even drawing both of them is not bad so might consider adding a third.
