Nice idea. A real intelligent chinese fake printer associate will change strategy to be among the first to mail in cards for trade in sensible quantities of 1 playset of each copy.
With the massive influx of trading in occurring, I am sure WOTC quality control will be bad, especially if they decide to rope in temp staff to handle this (which is likely) instead of experienced MTG old hands, and a fake trader can easily trade in his "old fake" for a "new confirmed real" stuff.
WOTC will only know the problem when they realised that the number being traded in outnumbered the original print run and I will assure you that WOTC will try to keep this a secret.
