About
Common Ground is a personal project that analyzes the Pauper metagame from the public results of Magic Online tournaments. It is free to use, and always will be.
Data sources
This project would not be possible without the community’s work:
- MTGODecklistCache (opens another site), by Badaro.
The original collection of MTGO tournament decklists (archived).
- MTGODecklistCache (opens another site), by Jiliac.
Maintained fork of the above; one of the two sources of MTGO decklists.
- MTG_decklistcache (opens another site), by fbettega.
Independent decklist cache; the other source of MTGO decklists.
- MTGOFormatData (opens another site), by Badaro.
Archetype classification rules.
- MTGOArchetypeParser (opens another site), by Badaro.
Archetype classification engine (MIT); the ingest uses a TypeScript port.
- Scryfall (opens another site), by Scryfall LLC.
Card data and images.
- Tagger (opens another site), by Scryfall and its community.
Card tags that group the lands into families (bounce lands, gain lands…).
Third-party data keeps its original licenses and terms of use. See each source’s repository or website for the details.
The tournament and deck data on this site combine both decklist sources. As part of it comes from MTG_decklistcache, it is published under the GPL-3.0 (opens another site) license.
Symbols and art
The mana symbols come fromMana (opens another site), by Andrew Gioia. The card art is the work of the artists credited next to each piece, © Wizards of the Coast, and is served from Scryfall. The mana symbols are also © Wizards of the Coast.
