For the parser I was inspired by the lightweight text format that scryfall uses, like[1]

  Llanowar Elves {G}
  Creature — Elf Druid
  {T}: Add {G}.

The rendering engine uses the Canvas API to compose the various visual elements. Implementing the rendering engine made me a lot more aware of card formatting details. For example hybrid frames vs. gold frames, accent colors, legend crowns, snow & nyx borders, information in the footer. There are a number of styling rule edge cases that had to be solved (a 2-color artifact uses those 2 colors in the accent, but gold for the type, name, and power/toughness boxes. But if the 2-colors are from hybrid mana, the accent is the same, but the name line uses the standard artifact color for the boxes).

This package also solves the problem of reinventing the wheel when displaying cards in a browser. It provides a React component which provides invisible text to make the cards ctrl+f-able, a context menu for copying the image or text of the card, and rotations for dual-faced cards.

This project had a lot of scope creep. MTG cards come in a variety of layouts, but it is heavily skewed towards "normal" (covering about 99% of cards) [3]. I had an MVP for rendering standard (or normal) framed cards in about a day. But I figured I should support all the primary card types, so I implemented support for Planeswalkers and Battles (about .1% and .01% respectively). Since Battles are dual-faced, I figured I might as well support transform cards and modal dual-faced. Then the Prepare mechanic came out in Secrets of Strixhaven so I should support that as well. In then end I supported just about every card layout, including split, flip, omen, adventure, aftermath, prototype, leveler. This greatly complicated the parser, rendering engine, and react component, but I am happy with how comprehensive the package is.

I've used this package for three projects so far (not including the playground page https://domainellipticlanguage.com/project/mtg-crucible-play...):

thismagiccarddoesnotexist.com [4] - a site for generating cards with AI

obsidian-custom-mtg [5] - an Obsidian plugin for making custom cards in markdown using a variant of the Scryfall spoiler text format

command-tower-mcp [6] - an MCP server for managing decks and custom cards on Archidekt.

> What actually happened here was that [...] two water hookups at a data center construction site weren't properly registered or linked to a billable account. When the utility noticed the problem, they sent the data center a retroactive bill for all the water, for $147,474 covering ~29M gallons. The data center paid it.

> Did the data center cause the low water pressure? The article very strongly implies a connection, but doesn't give the reader the right numbers to judge whether this actually happened. To figure this out, we need to know over what time the 30 million gallons was drawn [...] That's about 1% of the county's daily water output. There are a ton of ways a water system like this can experience low water pressure, and a 1% dip just isn't one of them.

> [...] the complaint about low water pressure [which led to discovering the billing problem] was coming from a private well that the data center didn't even draw from

Nit: The Split Second keyword ability is usually accompanied by reminder text which mentions the stack

> Split second (As long as this spell is on the stack, players can't cast spells or activate abilities that aren't mana abilities.)

Each player enters a prompt which an AI then draws. Then another player will guess what prompt generated that image. Then the AI draws that guess and so on.

At the end players can see how consistent each prompt stayed throughout the rounds. Here are the results from an example game https://dallestrations.herokuapp.com/ede93e19-ecb8-4d91-b973....

Actually uses stable diffusion rather than Dalle-2

Storing secret keys as QR codes is an interesting application as well. I remember reading on here about a CEO who printed out a database encryption key as a base64 string and then couldn't type it in correctly when it was needed to restore backups. A machine-readable format definitely seems the way to go.

I just saw a video the other day about storing video games in QR codes where the poster submitted a patch for ZBar. Was that you?
