Dandân

Why Play This Format?

Only one deck needed
Dandân (also known as Forgetful Fish) is a self-contained format where both players share a single deck. No brewing, no chasing expensive cards—just shuffle up the shared pile and start battling.

A true battle of wits
With a shared deck full of counterspells, card draw, and the legendary fish Dandân, every decision matters. Managing the top of the deck, timing your spells, and remembering what’s been played becomes the real challenge.

Fast and wildly replayable
Because the deck is carefully built to interact with itself, every game feels like a puzzle. Games play quickly, are easy to reset, and are perfect for teaching someone Magic or squeezing in a match between rounds.

Play Rules / Modifiers

Dandân is played one-on-one using a single shared deck. Both players draw from the same library and play from the same pool of cards. The deck is typically built around the card Dandân along with counterspells, draw spells, and ways to manipulate the top of the deck.

Players take turns drawing and casting spells as normal, but because both players share the same deck, knowing what cards are left—and remembering what has already been used—is a huge part of the strategy. Victory usually comes from resolving and protecting a Dandân long enough to attack your opponent down to zero life.

Games are usually best of one, quick to reset, and typically last 10–15 minutes depending on how many counterspell battles break out.

What makes Dandân special?
Unlike most Magic formats where deckbuilding and card ownership matter, Dandân turns the game into a shared strategic puzzle. Since both players use the same deck, the format focuses entirely on skill, memory, and timing, making it one of the most unique ways to play Magic.
