Wow, I didn't realize it gets that exponentially hard to level up. I guess I should just level up what I have so far. Part of me wants to sell off commons and reinvesting them back into packs in hope of getting more high value cards. Seems I'd have to sell a heck of a lot of commons to pull that off though. Might be cheaper just to buy the cards I want directly.
