I played this list from silver 2 to masters last season, and I'm working on it again this season. If I get to masters with it again and people are interested I'll write up a guide. Deck is really fun to play, and draws a surprising amount of cards. Maindeck feels pretty good but it's definitely not perfect. Also the market feels like it could use an extra counter-spell. Feel free to comment on what you think could be done better or if you play the list, what worked for you.
Edit: put unseal in for Kaleb, and intervention in for parry
