Komplex - presumably from the german for Complex, but in what way are they complex? More difficult to play or to be able to play them, less beneficial, or do they complicate the overall game?
Interactive - Given the Komplex and Easy names, you would expect this to be called Intermediate, as another named difficulty level. How are these cards any more interactive than any of the others? Is it to do with synergies?
Easy - same as question for Komplex, how are these actually any easier to play with than the others?
I ask this because I've now played with all of the decks (including mixed decks) and haven't really noticed any difference in game difficulty. If anything, the excellent buffs included in the Komplex pack seemed to make gameplay easier...
