I feel your trouble in making the wise decision.

I have been selling cards over the last two weeks as well. What I am selling are the ones I am not using to play with, because I do like to play nearly daily. From those profits I make myself buy a pack always (dice now it is, and they are also giving good profits) and selling some of theDEC. It feels in balance like this and not like I am killing my playing deck.

Somewhere along the line you gotta take some profits right?
