The official Tournament Rules 1.0 state:
"All Android: Netrunner cards produced by Fantasy Flight Games are legal for sanctioned play (unless banned)."
This is vague.
When, exactly, is a data pack legal for sanctioned play? If a data pack is legal on its release date, where can I find out official release date information for Future Proof, for example?
Another question: Can a Tournament Organizer declare a data pack illegal if the release date is the day before or the day of a Regionals tournament date?
