What's this?

A Frankensteins monster of a script, gluing different APIs and programs together. It's purpose? To generate completely new Magic: The Gathering cards from user prompts and make playable decks out of these. Does it work? Kinda. Is it fun? Definitely!

The script uses OpenAI GPT Chat api to generate cards and Dalle or Stable Diffusion for "art". These a given to Magic Set Editor which renders them into bona fide magic cards. With another prompt to the Chat api, a deck is build which output a "playable" deck in Tabletop Simulators Save format.

Example outputs:

Theme prompt	Generated cards
Cheese
cow
Shrek

Setup

1. Download Magic Set Editor (Lite is fine) and put it in a folder named "mse" https://magicseteditor.boards.net/page/downloads
2. Add your OpenAI API key as an environment variable named "OPENAI_API_KEY" - guide. Make sure the enviroment variable is available by restarting any open terminal sessions (including VS Code)
3. Install openai python package - pip - conda
4. Run main.py

Stable diffusion backend

It's possible to use stable diffusion instead of Dalle for art generation.

Setup

1. Install a stable diffusion webUI - I used AUTOMATIC1111's project
2. Add --api to the COMMANDLINE_ARGS line in webui-user.bat so it reads set COMMANDLINE_ARGS=--api
3. Start the webui using the startup script
4. Change the render_card backend parameter to stablediffusion

Notes

1. Enchantments sometimes have effects with no trigger.

TODO

1. Better checking of missing fields
2. Better deck generation
