Tonight I cruised through my life splinter quest pretty quickly. I did make it to Silver I just after finishing my quest. I received these cards as my reward.
I also opened up a beta booster pack. Here are the cards that I got.
My beta booster cards seemed to follow my daily quest today in that they were mostly white. I was pleased to get a summoner.
Do you have any beta boosters left? Mine are running thin... very few left.
