You did so well considering you're very new to the game and still getting to know your cards :) A win is a win!!! I think moving forward, brawls wise, you could easily become our bronze specialist. Competing in bronze is, I think, one of the hardest aspects of the game. Minimum abilities, low mana caps.. Its a tough level to be on. You gots this!!!!! Just keep getting to know your cards and what they can do.

I must say, I was very surprised to win my first battle. It was unexpected and set some (maybe unrealistically) high expectations for the remaining battles. I was thinking about it all day at work and couldn't wait to get home so I could log on to see how the rest of them played out. All in all, it was a fun experience to be part of such a great guild team.
