# Dandân: The Shared-Deck Format That Breaks Your Brain

Magic: The Gathering has no shortage of formats, but some of the most interesting ones weren’t created by Wizards at all. **Dandân**, also known as _Forgetful Fish_, is a fan-made format (created by [Nick Floyd](https://bsky.app/profile/magicstorytime.bsky.social)) that turns Magic into a battle of memory, timing, and restraint.

It is minimal, strange, and deceptively deep... and now you can play it here on ManyTCG.

## Why do people call it Forgetful Fish?

The entire format revolves around these two cards:

<BlogCards cardIds="MTG-CHR-18,MTG-DDM-24" />

- **Dandân**, is the only creature in the deck and the primary win condition
- **Memory Lapse**, counters spells by putting them back on top of the shared library

Because both players draw from the same deck, every counterspell, scry, or tutor affects _both_ sides. A play that looks strong now might hand your opponent the perfect answer on their next draw.

Dandân isn’t about raw power—it’s about timing and denial.

## Ok cool cool, so what are the rules of Dandân?

Dandân is originally a two-player format where **both players share a single deck and a single graveyard**.

The rules are simple:

- Two players
- One shared 80-card deck
- One shared graveyard
- Each player starts at 20 life
- You lose at 0 life or by drawing from an empty library

Other than that, Magic works as normal. The complexity comes from how the deck is built—and how much information both players are forced to share.

## Ok... so why do people like this format?

Dandân rewards careful play more than almost any other format.

- Every spell reveals information
- Every decision shapes future turns
- Mistakes are hard to hide and harder to recover from

For newer players, it’s a crash course in stack interaction and tempo. For experienced players, it feels closer to a strategy game than a traditional Magic match.

And since all you need is one deck, it’s perfect for quick games or downtime between rounds. _Actually quick is a bit of stretch... maybe set aside a night for this one..._

## Sweet... What were you talking about again?..

Dandân proves that Magic doesn’t need complex board states or flashy win conditions to be compelling. Sometimes, all it takes is a shared deck, a forgetful fish, and the constant fear that your best play might help your opponent more than you.

If you’ve ever wanted to test your understanding of blue Magic—or just try something genuinely different—Dandân is worth your time.
