Core 2021 features a mix of new and reprinted cards. The set contains 274 cards and includes randomly inserted premium versions of all cards.
The featured planeswalker is Teferi. It also marks the debut of a new planeswalker, Basri Ket.
The Showcase card frames are based on the Alpha card frames, and look similar to the Signature Spell frames. Teferi, Master of Time features four subtly different artworks. The monocolored planeswalkers each feature three signature spells and a basic land depicting their home plane. Ugin features no additional cards beyond his planeswalker card.
Core Set 2021 is sold in 16-card Draft Boosters (one card being a marketing card), five planeswalker decks, the Core 2021 bundle, and a Starter Kit. There are no Theme Boosters, but instead Core 2021 is the first core set to feature Collector Boosters. A Deck Builder's Toolkit is also absent. In addition, Welcome decks are replaced by a Welcome booster, a ten-card sampler showing off flashy aspects of the game like legendaries, planeswalkers, powerful rares and showcase cards.
The draft boosters feature key art of three planeswalkers (Teferi, Liliana and Chandra). The Collector Booster features key art of Ugin.
