My latest article, The Evolution of MTG Draft Boosters, explores the history of the original booster packs in Magic: The Gathering. I cover changes over time in Draft Booster contents, card counts, and premium foils. Did you know a handful of the original MTG booster packs only contain eight cards?
The article includes a table featuring the pull rates of premium foils between Urza's Legacy and today. I believe it is the most comprehensive and concise foil pull rate information available. Thank you to those on the /magicTCG subreddit for helping me verify foil pull rates for booster packs from older sets.
