This depends on prices of skilled commons, rares, and junk URs, and a lot on the current enhancing fodder you have available, all 4 being constantly in flux. However, this is the main reason I made the tables for myself ages ago, to calculate the cheapest way to skill my cards. I am reluctant to share my findings as that would increase the demand on the type of cards I buy, which increases their price, throwing off my calculation.

These tables are here for everyone to figure it out themselves, but posting a solution would remove the advantage given by those who diligently do the work. &#x2014; Amphitere
