Synchronize MTG Arena draft assistants with the latest crowdsourced card ratings
Are you tired of having your draft overlay showing you obsolete, prerelease rathings of cards that don't reflect the meta?
Tired of having to alt-tab out to 17Lands or your own spreadsheet to check every card?
Now you can update all your custom card ratings at once, from 17Lands' latest data or from any CSV file.
Sign up for an MTGAHelper account and install the overlay if you haven't already.
You'll need your user ID which can be found on your profile page: https://mtgahelper.com/profile
Install Python3 and then the requirements:
pip install -r requirements.txt
Call python draftsync.py
Enter the set and the draft type you want to use, or just hit Enter to accept the defaults
Enter your MTGAHelper user ID
wait... (currently uploads are 1-by-1 so can take some time)
Done! Start up MTGAHelper, open MTG Arena, and get drafting!
This will simply dump the ratings from 17Lands into a file:
17-lands-$SET-$FORMAT.csv
without uploading to MTGAHelper. This lets you make your own tweaks before you upload.
Call python fetch.py
Enter the set and the draft type you want to use, or just hit Enter to accept the defaults.
DraftSync will accept any CSV as long as it has the following fields:
- idArena : this is the 5-digit id that MTG Arena uses for their cards
- rating : a 0-10 score for how good the card is
- note : free-text field for you to put whatever you like: personal opinions, in-colour or sideboard winrates, etc
You can have other fields in the CSV for ease of use when reading it (I usually have card name, set name, and colour), but they aren't used by the script.
Having cards from different sets in the same CSV is fine, just keep in mind that the more cards you have the longer it will take.
Call python upload.py
Enter your CSV filename
Enter your MTGAHelper user ID
wait... (currently uploads are 1-by-1 so can take some time)
Done! Start up MTGAHelper, open MTG Arena, and get drafting!
The project needs to map from a card's name to the 5-digit code that MTG Arena uses to identify it, because unfortunately 17Lands doesn't provide this directly.
We use a library file card_map.json that should be updated whenever a new set comes out. You can update your local version by running:
python card_id_map.py
