I found this pretty interesting to watch, (and if you watch it, be warned that I swear a lot) but I didn't notice any significant play errors, which is good. I was playing from two life, which meant that I couldn't be as aggressive with Kickback as I would have liked.
Despite that, I wonder if it might've been a good play to kill the Baleful Strix and start swinging with the dragon. Six a turn is not a small thing and might have shaken stonethorn into making a mistake. That's a long shot but it's possible. In the end though, I think I played it correctly, I just didn't get what I needed.
Still, it's fun to watch and it won't take much time!
