Year of the Gryphon will see another huge revamp to the way Hearthstone is played. Basic & Classic sets, which were always available ever since the game’s creation, are now rotating out to Wild. Instead of them, we’re getting a new Core Set, which will change at the start of every Standard year.
Core Set 2021 contains 235 cards (160 Class + 75 Neutral), including 29 brand new ones (technically 31 now that Bluegill Warrior and Stonetusk Boar are getting changed). The rest are Basic/Classic/Wild cards we already know – however, many of them are getting buffed to be more useful (old expansion versions of all the cards changed for Core Set will also get the same changes). According to the developers, around 30% of the Core Set will be rotating every year – which means that in 2022 we might have a vastly different set of cards, promoting other strategies. Core Set cards will be playable both in Standard and Wild formats.
Probably the best news is that Core Sets will be free for every player. Unlocking it will work exactly like unlocking Basic set now – you need to hit level 10 with a specific Hero to unlock all of its Core cards. In order to unlock Neutrals, you need to hit level 60 across multiple classes – so e.g. level 20 on Druid, Hunter and Paladin will be enough to unlock all Neutrals. If you already are above Level 10 on every class (and you probably are), Core Set will be unlocked automatically after it releases and you won’t have to do anything. Golden Core Set cards are obtained through achievements, based on your Ranked wins (with a given class for that class’s golden cards, and grand total for neutrals).
To answer your “should I disenchant Classic cards” questions. The way Core Set works is that those cards are SEPARATE from the ones you already own and are temporarily added to your collection (for as long as they remain in the Core Set – so at least a year, but it might be longer). So, for example, if you own Preparation already, Core Set won’t just add extra copies of the old card to your collection – they will be added as a separate card that you can’t disenchant. So you CAN disenchant the old version, but here’s the catch – if Preparation rotates out of the Core Set and you disenchanted the old one, you will no longer own any copies of it – so you won’t be able to play it in Wild and Classic. To put it simply – if you only play Standard, you can disenchant your Classic cards without worrying. However, if you also play Wild or you’re interested in Classic / any other future formats that might use those cards, you should probably keep them.

Strength Totem is replacing Wrath of Air Totem (+1 Spell Damage) as the new Basic Totem. You will be able to roll it from Hero Power (as well as other cards) instead!
