Something fishy just happened with *Magic: The Gathering*’s latest Secret Lair drop, a Chaos Vault offering that features a Dandan deck based on the unique 1v1 game format where two players share the same deck.

Originally pioneered by *Magic* player Nick Floyd around 1996, the Dandân (or "

Forgetful Fish") format focuses on the Dandân fish creature from the game’s very first expansion, *Arabian Nights*. The publisher, Wizards of the Coast, usually doesn’t sell decks as part of Secret Lair, but this latest drop — which went live on Monday at 12 p.m.

EDT — is an 80-card deck with 46 gorgeous, borderless foil cards and 34 cards with classic retro frames. Priced at $99, the drop was completely sold out within 27 minutes.
