The Android: Netrunner tournament rules say the choice of banned cards is up to the tournament organiser. With the single exception of banning "All That Remains" at world level.
All Android: Netrunner cards produced by Fantasy Flight Games are legal for tournament play (unless banned). No other cards or proxy cards are permitted. In North America, cards are legal upon their release. Competitors outside North America should check with their TO to determine which cards are tournament legal. Exception: All That Remains is not legal for the World Championships
