I like this except that is a bit strong for discarding commons and a bit weak for discarding rares. Maybe removing the keywords and adding more stock to uncommon/rare? (like 1/4/12)

Don't confuse the terms stock and resource. The card says it increases a random -resource- by the given number. In your comment, you increase the numbers but then refer to stock.

ohh right my bad, still thinking its to powerfull for discarding commons and not rewarding enough for rares but a very nice concept
