Card Farming? [GA INSIDE]

Others already answered the question, so pointless repeating the same stuff. That being said, I'm so lost on the sg rules, can't figure out why I failed.

Farming and selling is more beneficial than crafting really. I did it to support developers (over due to SGMA) or to get extra profits from holiday card sales (which prices dropped rock-bottom so really not worth it anymore, also damn SGMA). Now they just gather dust since no-one wants to trade from a non-SGMA and selling cards with a 15-day wait period is freaking impossible unless I set insanely low prices.
