How Magic: The Gathering sets usually behave
Value concentrates hard: across 393 measured Magic: The Gathering sets, the single top card typically holds about 8% of a set's total card value.
New Magic: The Gathering sets have typically settled about 34% below their release-week price, with most of that easing done within roughly 16 weeks (measured across 70 recent releases).
Over the first 30 weeks after release, that easing runs about 28% deeper than the market's own drift.
Across 71,958 measured breakaway moves in our archive, upward moves outnumber drops about 1.5 to 1.
