Once a year Blizzard changes things up with our beloved Hearthstone, rotating old card sets to become Wild-only, severely limiting the Standard card pool and making drastic changes to the meta. This can all be a bit confusing, so here's the definitive answer to how set rotations work. Below you will also find historical information on each of the rotations we've seen.

Set Rotation Basics

  • Once per year with the release of the first expansion, usually in April, the rotation takes place.
  • *NEW FOR 2021* A Core Set will always be a part of the game.
    • Some cards in this set will rotate out, bringing in older or brand new cards into Hearthstone's "evergreen" set.
    • Prior to 2021, these non-rotating sets were the Basic and Classic sets.
    • Any card that gets kicked out of the Core Set will return to its original set.
  • Standard format, upon rotation, is restricted to sets released in two calendar years. (2019 = sets from 2018 and 2019).
  • The first set of a year also marks the new name of a "Hearthstone Zodiac" year. (Kraken, Mammoth, Raven, Dragon, Phoenix, Gryphon).

2021's Set Rotation Overhaul

  • A Core Set has been introduced. This replaces Basic and Classic though sees some of their cards available.
  • Cards from Classic and Basic have been moved to the Legacy set if they don't belong to another set.
  • The Hall of Fame was removed from the game. Cards went back to their original sets.
