Hearthstone: Heroes of Warcraft's second season of Ranked Play is drawing to a close today. It will be followed immediately afterward by the start of Season 3, fresh with a new card back to earn.
Season 2 of Ranked Play allowed players to earn a green card back inspired by the Black Temple. To get the card back, you have to earn Rank 20 by season's end. It's an easy feat to accomplish, because losses from rank 25 to rank 20 don't hurt your progress to the next rank. It should only take a handful of wins in Ranked mode to get to 20.
If you haven't gotten to Rank 20 in Season 2 yet, you've still got a little time. Here's when the season will end in each territory:
The new card back for Season 3 is this rainbow collectible. It doesn't seem to have any specific inspiration from World of Warcraft.
The Season 1 and Season 2 card backs won't be available in Season 3. However, you can still try to attain the Fireside Friends and Legend backs. The former is earned by playing local matches. The latter is awarded when you hit Rank 0 for the first time.
Hearthstone's third season will run until June 30th. It could be a very challenging month. Blizzard plans to release the Curse of Naxxramas single-player adventure this summer, complete with new bosses and cards. These cards could severely tip the balance toward one class or another. Blizzard hasn't dated Naxxramas yet, though, so perhaps it'll miss this season.
