In an attempt to mix things up, Blizzard has decided to create a new way to play Hearthstone.
If you’ve played other competitive CCGs, such as Magic: The Gathering, then you’ll easily understand what Hearthstone is about to do. However, if Hearthstone is your first CCG then things might be a little more complicated.
Starting this spring, Hearthstone will be separated into two different formats: Wild and Standard. Each format will have a separate ranked queue and both will allow players to complete quests. Technically, Wild will be the same Hearthstone that everyone knows and loves. Standard, however, will only allow the use of cards released in the current and previous calendar year. This will allow for a constant shift in the meta and more freedom for future card develop.
The first series of Standard sets in Hearthstone will include: Basic, Classic, Blackrock Mountain, The Grand Tournament, The League of Explorers, and the upcoming Spring 2016 Expansion. That means Curse of Naxxramas and Goblins vs Gnomes will not be part of the first Standard set.
Furthermore, Adventures and Expansions that get phased out of the Standard set will no longer be available for purchase from the shop. All of these cards, including those from older Adventures, will be available to be crafted with Arcane Dust. However, if you already own one wing of an Adventure you will be able to unlock the remaining wings at any time.
Now that Hearthstone has a fairly large set of cards, it was definitely a good call to introduce different game formats. This keeps things fresh and means developers don’t have to balance cards based on sets from years ago.
