To add a bit more clarity to the set availability and rotation sequencing:
- The "Core" set is free, and rotates every year.
- Get each class to level 10 to earn their Core cards
- Earn all neutral Core cards once your various class levels add up to 60
- After you've done this once, you've done it forever, because your class levels never decrease - you'll have the full Core set each rotation
- Each year, three expansions are introduced. They remain in Standard until the first expansion is released two calendar years later. Then they rotate out of Standard and are only usable in Wild.
- Here's the sequence:
- 2019 April: Expansion 1, 2017 expansions rotate to Wild
- 2019 August: Expansion 2
- 2019 December: Expansion 3
- 2020 April: Expansion 1, 2018 expansions rotate to Wild
- 2020 August: Expansion 2
- 2020 November: Expansion 3
- 2021 March: Expansion 1, 2019 expansions rotate to Wild
- 2021 August: Expansion 2
- 2021 (Nov/Dec): Expansion 3
- 2022 (Mar/Apr): Expansion 1, 2020 expansions rotate to Wild
So, given that Expansion 1 launches around March or April of a given year:
- Cards from 2020 will be in Standard for ~7 more months
- Ashes of Outland
- Scholomance Academy
- Madness at the Darkmoon Faire
- Cards from 2021 will be in Standard for ~19 more months
- Forged in the Barrens
- United in Stormwind
- (upcoming expansion in Nov/Dec 2021)
