Here's a picture of a recent pack that I opened. Like my other packs, it was from finishing a daily quest. I'm starting to get more of the different cards which has been helping in the battles. It helps to have more to choose from.
I haven't been keeping very many duplicates either because I want to get one of each before I start leveling them. I don't want to have a strong team for one color, but not for the others. I'm happy I got three blue cards in this pack though. Maybe one day I'll get all 5 from the same color.
