This is a very specific tool I made for me and some of my friends who play Magic: the Gathering. We have a "You Make the Card" channel where we design our own MTG cards.
This bot will scrape a discord channel for Magic: the Gathering cards and save them as a Cockatrice XML file.
Accepts plaintext mana symbols and also emojis from https://github.com/scryfall/manamoji-discord
Still has a lot of parsing issues, but is at least somewhat usable at the moment.
