Throne of Eldraine is the 82nd Magic expansion, released on October 4, 2019. The set is themed around classical fairy tales, Arthurian legend and other pieces of mythical fantasy, taking placing on the plane of Eldraine. It is perhaps most notable for its historically high power level, leading to a record number of cards banned across multiple formats.
Throne of Eldraine’s most powerful cards come in the form of Oko, Thief of Crowns, Once Upon a Time and Mystic Sanctuary, which have been banned in a variety of formats. Outside of these three, a multitude of other cards have been banned in either Standard or beyond, including Fires of Invention, Cauldron Familiar, Lucky Clover and Escape to the Wilds. Oko in particular has received the most bans of any Magic card, being banned in Standard, Historic, Modern and Legacy.
Multiple powerful mechanics were also introduced in Throne of Eldraine. Adventure cards, which can be cast as an instant or sorcery then cast as a creature later, were the centerpiece of multiple top tier Standard decks. Additionally, Food, artifact tokens that can be sacrificed for life, became popular with Modern Horizons 2, introducing The Underworld Cookbook and Asmoranomardicadaistinaculdacar.
Throne of Eldraine notably was the first set to introduce Collector’s Boosters, as well as widely available borderless and “showcase” styles (although borderless cards first appeared as box toppers for Ultimate Masters). All Adventure cards had an alternate showcase “fairy tale” art style, with the rares and mythics of the set coming in a borderless treatment as well.
Along with Draft and Collector’s Boosters, Throne of Eldraine also brought the first (and as of writing, only) Brawl preconstructed decks. These 60-card decks contained unique, Standard-legal cards. Korvold, Fae-Cursed King notably has become the second most popular commander in EDH, according to EDHRec, as well as a key card in sacrifice decks in Historic and Standard.
