Common questions

Where does this data come from?

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.

What counts as a biggest set mover?

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.

What does most valuable mean here?

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.

How often is this updated?

Once a day, alongside Hoard's overnight market rollup. The "as of" date on the page shows the last update.
