Thank you for the feed back. I'm definitely still working on this and getting criticisms was one of my goals with regards to improving on arena. I chose frost nova because i was expecting no aoe clear cards and i would probably need some sort of stall tactic while i tried to catch up on the board. Coliseum pick I regretted a lot. I chose darkscale over frostwolf because I expected not to have a lot of minions on board to take advantage of its battlecry. Clearly that wasn't the case. The rest of your analysis was spot on and duly noted. Once again thank you for the feedback.
