Plus, points have inherently higher value to packs. They can be used to buy singles, packs are a gamble. It's why I'd rather hand out a pack compared to a set amount of points.

Maybe have certain rarities of cards be worth certain "Trade Points", and say you need like 20 points to get a pack. You could trade a couple rare cards that you don't ever plan on using for a chance at getting a better pack, or you could just trade a bunch of fodder/stuff you will never use anyways. That'd probably be a pain to calculate though.
