Magic Game Day

Magic Game Day is a seasonal Magic: The Gathering tournament organized by the DCI. The tournament is played in local game and hobby stores around the world, a month after each a new card set is released. Game Day events are Standard format tournaments, using only the newest cards the game has to offer. The events present one the first opportunities to discover how the new cards shape the Constructed metagame. All participants receive a promo card (while supplies last). From 2009 on, Top 8 finishers received an additional card.

The first Game Day was on July 14, 2007, in commemoration of the release of 10th Edition. All participants received a promo card (while supplies lasted), and starting in 2009, Top 8 finishers received an additional card. All cards except the first two are full-art cards. In addition, all top-8 cards are foil.

The last Game Day was on August 6, 2017 for Hour of Devastation. After this, Game Day was renamed to Store Championship and moved to the end of a set's season.
