Magic: The Gathering cards rising in price the most over the past week, month and quarter, ranked by percentage gain from Cardmarket and TCGplayer market prices.
A price spike is a rise in a card's market price between two dated price snapshots — the past week, month or quarter. Cards are ranked by percentage gain or by absolute price gain over non-foil prices only, and only printings that were already worth at least 0.50 in the source currency are considered, so bulk cards jumping a few cents don't crowd out real movers.
Prices come from Cardmarket (EUR trend price) and TCGplayer (USD market price) and are snapshotted with every data refresh. Your selected currency decides which marketplace's data is shown, converted for display.
When a card spikes, its reprints usually move together. To keep the list informative, only the printing with the biggest percentage gain is shown for each card name. Foil prices are excluded — they're driven by thinner supply and spike on single sales.
Each period compares the latest price snapshot against the snapshot closest to 7, 30 or 90 days earlier. The exact snapshot dates being compared are shown above the table, so a gap in the refresh schedule never silently changes what you're looking at.
