WotC recently announced the details of the Mythic Invitational, and confirmed that they will be announcing a new Secret Lair drop during the last day of the event. "Fans of past Zendikar sets should know we're announcing a Secret Lair drop during the broadcast on Sunday, September 13," Wizards said.
Each Secret Lair drop usually focuses on a theme for the unique alternate-art cards featured in the box, and since WotC addressed the "fans of Zendikar", the new limited edition print-on-demand product will most likely feature a Zendikar theme. It might be Eldrazi, Landfall cards, or perhaps trap cards from the original Zendikar block.
What cards do you think will the new Secret Lair feature? Let us know in the comments below.
