September 8, 2021 Banned and Restricted Announcement
Announcement Date: September 8, 2021
Chatterstorm is banned.
Sojourner's Companion is banned.
Magic Online effective date: September 8, 2021
Storm combo decks had the highest non-mirror match win rate among top decks in Magic Online leagues. To address Storm's high win rate, metagame share, and difficulty to interact with, we are banning Chatterstorm.
Affinity has just under 50 percent non-mirror match win rate—however, its win rate against many less represented decks was high. To open the metagame to more diversity, we're choosing to ban Sojourner's Companion.
The list of all banned and restricted cards, by format, can be found here.
