Secret Lair: Ultimate Edition was the first Secret Lair Drop Series set that was made available to retailers through the hobby distribution channel, and it featured the pricey, in-demand enemy-colored fetch lands with new artwork (see "Finally! A 'Magic: The Gathering' 'Secret Lair' for Retailers"). With market value of the sitting at around $324.12 plus shipping (according to TCGPlayer at the time of this article's publication), it stands to be the most expensive Secret Lair Drop Series set offered yet. Unfortunately, due to this delay, it looks like retailers will have to wait just a little bit longer to deliver this product to their customers and finally ring the register off of WotC's Secret Lair Drop Series.
Wizards of the Coast also revealed the product range for its Magic: The Gathering - Core Set 2021, and the Magic Arena Starter Kit , which are both due out July 3 (see "WotC Reveals 'Magic: The Gathering - Core Set 2021' Products and 'Magic Arena Starter Kit'").
