Core Set 2020 was released on July 12, 2019. It contained 280 regular cards and 64 special product and promotional cards. For the first time since 7th Edition in 2001, Disenchant was included in a standard legal set and for the first time in a set supporting all 11 languages.
Starting with Core Set 2020, the frequency of foil cards was increased from 1:67 to 1:45. When they were first added to booster packs (Urza’s Legacy in 1999), the rates were 1:100, some years later changed to 1:80. Core Set 2020 was also the first set entirely printed on a new developed card stock (first usage War of the Spark second print run). The cards seem to be more elastic compared to those from the past couple of years.
