Same here!! I barely got the beta rares to at least level 6 before they really started becoming unobtainable in the numbers I still need them. Having to drop hundreds more dollars just to be able to finish upgrading playing cards makes it feel like I'm not really going to advance any farther than I have.

On another topic, @yabbapmatt, how long before we start seeing other variations or entirely different games we can use these for? I recently thought it might be nice if there were a version in which the player chooses two teams at the start and replacements slide into play as positions open up. Or tag team, so every card tags out when it takes damage. I also think there's a very powerful Dungeon Master tool buried in here, too, but that's a whole other thing.
