Modern Deck Information

[imsolost]

Hi, I saw your mtgtop8 data gatherer and I was wondering if you could help me understand how it works. I want to create something similar to pull the data for all available modern decks across all time periods. I would like to use this information to plot how well various archetype's place at tournaments or in daily events. I believe the code you provided could do something similar, but I am relatively new to this language so I wasn't entirely sure how your code works. Any help would be appreciated.

Thanks!
