Here is a list of the limited edition command cards that were included in the previous three Lords of War Kickstarter campaigns (and at cons and tourneys). These cards are optional and are used by swapping them with one of the standard command cards of that faction. As far as I know all of them are in circulation as both normal and foil prints. There are also foil versions of all standard command cards in circulation (from all core and expansion sets). The easiest way to get them was to buy them in bulk as add-ons in the 3rd Kickstarter.
