Notes
All main cards are the FFG LCG standard 63.5x88mm (fits any standard/MTG sleeve). Count depends on edition: the new 2026 Core Set has 224 player + 133 scenario = 357 standard cards; the 2021 Revised Core Set had ~229 player + ~120 encounter cards; the 2016 original had far fewer. Confidence set to check because the retail edition is in transition and the exact size of the 5 mini investigator reference cards (~Mini American) is not independently published. Community often sizes FFG LCG cards up to Chimera for an easier shuffle fit.
