Secret Lair: Dandân Decklist

Secret Lair: Dandân is a complete deck for the Forgetful Fish format, first created by Nick Floyd in 1996, which revolved around the card Dandân. The format gained mainstream relevance starting in 2023. It was first hinted at in January 2025.

In Forgetful Fish/Dandan, players share an 80-card deck and the graveyard. It is played much like any other game of Magic: players start at 20 life, they draw a hand of seven, and they discard at the end step if they have more than seven. Players can lose the game if they draw from an empty deck.

Opening hands are dealt like a game of poker: one card for the first player, one card for the second player, and repeat. If an effect causes both players to draw a card, the active player deals the cards in the same fashion as the opening hands, starting with themselves. If an effect returns a card from “your” graveyard or library, it refers now to the shared graveyard/library. Also, the “owner” of a card is its caster.

Players may first take one or more free mulligans for hands containing less than two lands or spells, revealing any hand not meeting these criteria; then, once the previous criteria have been met, they may opt to take further mulligans for which standard rules apply.

The Secret Lair: Dandân is scheduled to release at the Chaos Vault on March 16 for $ 99.99. It comes packed with 80 cards, including 46 borderless foil cards featuring brand-new artwork. The remaining 34 cards keep it classic in retro frames with updated formatting and the Secret Lair (SLD) set symbol.

20x Island

10x Dandân

8x Memory Lapse

4x Accumulated Knowledge

2x Magical Hack

2x Mystic Sanctuary

The full decklist was first unveiled at MagicCon Atlanta. It is now confirmed to be the same list to be shipped on Wizards of the Coast official website.
