RW equipment, I've been testing it for two weeks now. It fits into the meta as an outlier, and I have sideboard tech for the biggest decks I'll see there.
Radiant flames, hallowed moonlight, felidar cub, roast, etc
I know you've been testing it for a while, but mtggoldfish put out a list and video of it today, just a heads up in case they have any card you may have missed.
