Since Un'Goro there are quest cards in Hearthstone, that, after played, require a certain amount of specific actions to be performed to activate an effect. Each class currently has one quest.
What is the earliest turn as starting/second player for each class to activate their respective quest?
This could include a random hit like Swashburglar grabbing a spell or Thoughtsteal acquiring a deathrattle minion.
