I started out BG, but won only one game out of seven across three matches. For the final match I went WB but also lost both games. After an extensive evaluation of my card pool, it seems that making the switch from BG to WB was good, although it probably would've been even better to switch to BR.

Overall though, my card pool was really poor. Not a single mythic rare and no bomb rares. I had a few good commons and uncommons, which allowed me to start out strong and hold on for a significant amount of time, but I had no finishers so my opponent was always able to stabilize, take over and win.
