New Stormwind Quests?

Hello!

I keep getting a quest to play through part of the Stormwind storyline but… where is it? Which game mode can I find it in?
I’ve been looking everywhere.

Also, do all modes count for the “play 3 games” quest? I tried a casual one and it didn’t work.

Thanks for the help, all.

Questlines are legendary cards. There is one for each class. You need to own the card, and then complete a series of steps to get the quest reward. You do not need to play the quest reward for it to count. For more information, look up Hearthstone questline.

Quests do not work for casual at the moment. Normally they do, but there’s a bug with the latest patch.
