They're only giving you two weeks to get the Cardfolio ML vol.2 set for some reason, it has a separate card pool of Hotchpotch 2 outfits in addition to ML 12th art (and the two mystery Master Rares), so they're a better choice than Volume 1 provided the idol you want was part of the live.

No Super Rares in this but the Million Live Rares are present with shiny idol autographs.
