maybe we could try a different approach, a couple players (probably the forum moderators and the administrators) can introduce the card(s) in a deck and play a couple games among them. See if the cards are playable, if a game would be fair using these cards. Ofcourse not all cards will be passed for this test, otherwise there would be too much work, but this could allow for more cards to be marked as "interesting", then they get tested and then if the decks are balanced with the new cards, then apply them to the real game. Thus there will be more cards coming in. I must say i've been playing this game for 2-3 months and i really love it, but with the exception of the last update, there weren't many cards introduced. we are playing for fun, not for money or anything else. So in my oppinion if someone makes a card and then sees it in a game, well he/she will feel some accomplishment and contribution to the whole community and have fun as well. introducing more cards by more players is something discussed widely and i think it should go more than just words :)
again this is my oppinion, i might be wrong, but this testing system will be allowed for more cards to be viewed and thus for more concept cards to be accepted. Also it will help the game evolve further. Let's not forget we are playing a game invented by 3DO almost 10 years ago, and we love it, because we sort of made it something ours (although most of us never contributed anything to it)
