TL;DW:
Starting November 7 2018 at 10:00 am PDT through November 11 2018, everyone who logs in will receive six free Boomsday Project card packs.
Then hang out and play with friends to earn up to 500 gold! Everyone will receive the Celebrate the Players quest which rewards 100 gold when you play a friendly challenge. This celebratory quest is repeatable up to five times—you can even do them all in the same day!—for a total of 500 gold!
You’ll need to complete the introductory quests “First Blood” and “The Duelist” to unlock daily quests, (or “Ready for Action” if you’re a returning player). Be sure to make room in your quest log before November 7 so you don’t lose a quest you intended to complete. Just like Play a Friend!, don’t concede too early, or you may not receive credit for completing the quest. Unlike Play a Friend!, Celebrate the Players only provides rewards to players who have this quest in their own quest log.
