The second of four Hatsune Miku Secret Lair releases has sold out, and pre-order prices for the exclusive Magic: The Gathering cards are sky-high on the secondary market.

Wizards of the Coast crossover with Hatsune Miku, a Vocaloid voicebank, is paying off, as the second of four MTG Secret Lair drops has sold out once again. The first set, Sakura Superstar, was released via the Spring Summer drop. Prices for the Hatsune Miku Sakura Superstar set were initially high, but stabilized towards the summer. Drop two, Digital Sensation, was in the Secret Lair Summer drop which runs until July 14th. Both the foil and non-foil versions of Digital Sensation sold out shortly after release, just like the first set, and are following the same pre-order price spikes for singles on the secondary market.

Sealed prices for non-foil Hatsune Miku Digital Sensation boxes were selling for $29.99 and rainbow foil boxes were $39.99. At the time of writing, non-foil and rainbow foil singles have pre-order prices of $25 and up, per TCGPlayer.

Inflated prices like this are normal, especially for products that are sold out for a limited time, like the Secret Lair Hatsune Miku Digital Sensation boxes. If the second set follows the same trends as the first drop, prices should drop to the $10-$20 range once the cards start shipping out to collectors.
