Patch 20.0.0.77662 (2021-03-25): Deck Selection's side view has a new appearance.
Moved the Seasonal Ranked Rewards Chest to the Deck Selection screen.
Instead of switching modes between Standard and Wild, the player can now choose one of four following modes: Classic, Standard, Wild, Casual.

Starting from Year of the Gryphon, Classic is used to refer to cards, game modes and adventures which are only available in Classic format. Classic format is the only format whose cards are completely unrelated to other formats in Play mode.

The symbol for Classic format is a swirl symbol formed from laurels.

The first hint at the year's new features began on January 8th, 2021 as Alec Dawson and Cora confirmed that Edwin VanCleef would be rotated to Wild but would not be entering the Hall of Fame[19][20][21]. Announcements for the sixth standard year begin on February 9th, 2021 with the announcement of the Core and Legacy sets, removal of the Basic, Classic, and Hall of Fame sets, and introduction of Classic format.[22] While the year was currently unnamed, these were the headline features planned with its release. The year was officially announced at Blizzconline on February 19th along with the reveal of Forged in the Barrens.
