Does Wizards make this information available? This would be a really cool machine learning problem to try and predict which decks do better against which decks based on their cards.
For example, for Pro Tour Ravnica, I've found the full match lists at: https://magic.wizards.com/en/events/coverage/ptgrn/tournament-results but I'd need to scrape it from the web.
The decks however, I can only see:
- top 8 full lists e.g.: https://magic.wizards.com/en/events/coverage/ptgrn/top-8-decklists-2018-11-10
- archetype percentages, e.g. https://magic.wizards.com/en/events/coverage/ptgrn/3-0-drafts-day-1-2018-11-09
For Magic Online, it would be even more awesome if we could have full play by play data of tournaments: Is there a standard file format for Magic the Gathering games? to decide e.g. how much a turn one Black Lotus increases your win rate.
https://www.mtggoldfish.com/articles/wizards-data-insanity from 2017 mentions that Wizards has controlled this kind of data more and more so I'm not very hopeful.
