I still don't see the large concern with overrunning the 'other' category by pseudoquanta cards.
The way cards make it far in the system is by having excellent balance, being creative and being a crowd favourite. If pseudoquanta cards are simply better liked, then yes, they're rightfully overrun the category. If Darkness cards end up being the crowd favourites in the Forge, do we worry that too many are in the Armory?
The "Card Ideas and Art" section is for just that, "ideas". Pseudoquanta present a new idea to the table much like any other card that is submitted to the crucible. We're offering a well of idea that may or may not even make it to the game, but in the end, they're simply ideas. This is the essence of why I think this confusion is absurd.
