I don't know... even with the way things are now... there is no guarantee that each card could be paired up in a way that they would be fully powered up? Plus, there is only so far they can go with adding new abilities before it devalues others too much or becomes a bit ludicrous to keep track of (keeping in mind that it is a casual game and not a hardcore strategy game!).

The burning would be an option... it isn't neccessary for people to take it, but it would go some way to reducing the glut. I think the glut is more demoralising to the economy and players at the moment?
