Actualy I dont think a TCG would be too great, but if they made AG Poker Cards, now that would be cool!
Have the AG logo on the back of each card, They could remake the jacks, queens, and kings to a more cartoon like style (the armatars and their artstyle would make a great poker card style.)
TCG, I think it would be a flop, we have less than 200,000 members (and over 50,000 are inactive). The chances of you finding someone in your neighborhood with their own deck of AG Trading Cards would be very rare.
Now Poker Cards... you only need one person to own a deck to get a game started. If you have 5 friends play a poker game with them, you have a good chance of some of them becoming members of AG themselves.
