Blackmoor wrote in Difference Between Editions of the Blood Wars CCG:Not 3 editions but actually there was the Basic game and 3 different card expansions.  

Each expansion a contains additional powers and stuff to add more variety to the game.

Fulnitus wrote in Difference Between Editions of the Blood Wars CCG:The 'editions' of the base game are just different print runs of the starter decks. You can tell on the starter deck box:

-first edition coded 1128
-second edition coded 1128B and shows a II in roman numerals on both the boxes and the cards
-third edition should be coded 1128C (don't have any 3rd cards or boxes myself) and should show a III on box and cards,

The cards and art are all the same for these (300 cards).

Then there are the 3 series of expansion packs - all of these only have 1 printrun, so no II or III on the cards:

-Rebels and reinforcements (299 cards out of the base set, plus 33 new chase cards and one ultra rare the Lady of Pain). The card from the base set not included is Bladeling Hero which is only found in starter decks.
-Factols and factions (134 cards)
-Powers and proxies (134 cards).

If you need a list of cards, more info or would like to trade just let me know.
