These files contain all the currently-available D&D Miniatures RPG and skirmish stat cards that conform to the revised (post-Dungeons of Dread) rules. Printouts of these cards are legal for use in DCI-sanctioned tournaments unless they are labeled BETA or DRAFT. You still need official, legal miniatures, of course (which includes approved Chainmail figures and certain modified plastic figures). Those allowances and restrictions are covered in the DCI Floor Rules.
You should also visit the DDM Guild site for the latest errata, FAQ, and clarifications.
