Hoard's own daily rollups of live TCGplayer market pricing across every tracked Union Arena product — not scraped or modeled from someone else's listings.
The sets with the largest 7-day percentage change in their price index, up or down — ranked by the set's overall index, not any single card's price. A set needs at least two dated readings inside that window, and a real price above a few cents, to qualify — brand-new, thinly tracked, or bulk sets are excluded so a rounding-level move doesn't read as a market swing.
Sets ranked by total market value: the sum of the current market price across every tracked product in the set, not any single card's price.
Once a day, alongside Hoard's overnight market rollup. The "as of" date on the page shows the last update.
