This deck eventually beat Steven's Rakdos deck, despite some frustrating losses to that card specifically. (It felt like no matter how well I was doing, his grull-rakdos deck could just suddenly win). I think there was a good bit of luck involved but chillbringer was huge in keeping damage in check, and if neither of us got our mythics out (I got mine less often but still won the series.) I could dampen his attacks a bit and then try to go over the top. It looks like I took out open the gates for a Steeple Creeper at one point. Then, probably a much smarter change in the last match of taking out Titanic Brawl for another Steeple Creeper. (I often couldn't fight his creatures as they were just as big or bigger than mine, but going over the top was something he had a hard time with). I underestimated the creeper because of its low toughness but being able to jump, even if its expensive, puts a lot of power in the air. The Azorius guy was probably a riskier trade for the bounce spell, and I should have had more white, but it was a good safe way to prevent some of his damage while still jabbing him down, had I gotten it out there.
