It's been a while since I've done a run--after that great Mage run went 2-3, I went on tilt a bit, doing a crappy Hunter run (done mainly for quests) that went 2-3 as well, then joining the dark side with a Paladin run that started 0-1 (all in one sitting), then I went away from Arena for a bit. I just came back and finished up the run, and it somehow managed to get to 7 wins! It seemed average to me, other than the one Murloc Knight--being on the winning side of it hasn't convinced me it's anywhere near fair by the way; I can just look at the match where I ended with 3 Murloc Knights on board 
A Shaman run's coming up next--I like Shaman, though I haven't done one yet in the HearthArena era, so it'll be interesting
Edit: Here's the run. It's interesting, especially in the way the curve values Overload cards--it considers Totem Golem to be a 3-drop, but not Fireguard Destroyer, and doesn't put Feral Sprit on the curve at all!
I'm also surprised at how low it valued Dunemaul Shaman--I mean, I probably don't take it over the Knife Juggler, but only ~30? It feels like you're getting a lot of raw power for relatively minor drawbacks (Overload 1 and the 50% misaim). Does it value all the 50% misaim cards that low? Maybe I'm undervaluing that drawback--the only time it's really bad is when there's something you need to kill, or it suicides into a bigger creature (which you can work around if it happens)? Or maybe the tier assumes it'll just die before it attacks, in which case you're paying 5 for a 5/4? Maybe I'm overvaluing Windfury, just because of how swingy it is (though I've had enough bad experiences with Whirl-o-Matic to know Windfury isn't worthless)?
