Release history

Is the game slowing down or speeding up? Here is the whole release timeline as a running total, one dot per release that added something, with a straight-line trend through it. Pick the measure of "content" you find most honest. Numbers come from the card database, up to August 21, 2026 (63 releases).

69 heroes so far. Averaged over the whole run, the collection has gained about 9.8 heroes a year.

All cards is exactly that: every copy printed, filtered only by the measure you picked, so four Energy in a box are four cards and so are the four in the next box that reprints it. Playable copies instead counts each card for as many as one deck may run, once across its whole history, so a reprint adds none. No R² is quoted: a running total climbs by definition, so a straight line fits one whatever the release schedule did. Card data is the community-maintained MarvelCDB card database, which fills a new box in over the days after it hits shelves, so the newest release can read low for a week or two.
