I'm glad this thread got some attention. Yes, I actually do believe that having every possible combination of dual pillars would be good. This is already a lot of cards if you think of how many combinations there are, and we all know this game needs more cards. In addition to adding more bulk to the card base, this will unlock previously untapped potential in most, if not all cards in the current selection. How these are circulated into the game is entirely up to Zanzarino, but I think this idea is very promising.
