From the announcement:
Privateer Press announces the completion of its online stat card database for WARMACHINE and HORDES. All cards for all models that currently exist can now be found and downloaded for free at cards.privateerpress.com. In addition to all cards now available online for free, all rules for WARMACHINE and HORDES can be downloaded for free at privateerpress.com/rules. Printed stat cards are no longer included with models.
Star Cards for future model releases will be added to the database on the day the models are first made available for purchase and will coincide with War Room 2 updates. A Card Version List is available at privateerpress.com/rules, providing players with a reference document of any recent changes or additions to the card database.
