So what we can do for now is just complete Daily Quests and get our armies stronger in preparation for Season 3. What the new season reserves for us we cannot know, but we can just wait and see.
Moving to my Daily Quest I had the luck to fight with the Death Squad which I believe is one of the strongest and soon brought me a Booster Pack.
Getting me a gold card (Level 4) is quite amazing and hopefully there is more to come.
