Secret Lair

Chaos Vault: Dandan

Chaos Vault: Dandan, released in December 2025, wasn't built around its basic lands at all — it revived Forgetful Fish, a community-designed nostalgia format built around a single blue fish creature, packaged as a full 80-card two-player experience with new Dandan artwork. Four Island copies came along for the ride as part of that deck, rather than as a standalone themed land cycle.
