A new eight-card drop every week. In season: the newest MLB call-ups as Rookie Debut cards. In the offseason: players whose rating moved up during 2026 (opening week to the latest rating at the time of the drop; some picks come from the backfill when fewer than eight clear that bar). Collect them in packs, trade them on the marketplace, or chase the upgrade.
Rookie Debut cards are generated automatically when the nightly roster transactions ingest detects an MLB call-up, typically within 24 hours of the player’s debut. Risers are ranked by the change in overall rating between the first rating snapshot of the season and the latest one, minimum rating 88. Ratings refresh nightly; see our methodology.
