Why did the values of so many Revolutions rares drop?
Most rares in Revolutions are not the most powerful cards in the expansion, but instead, cards that are less likely to be used by most players. Unfortunately, the relative rarity of the Revolutions expansion has artificially inflated the values of those cards, and the effect has never been corrected. I felt that the increased numbers of Revolutions packs brought into circulation, combined with the relative quality of Revolutions cards should lower their values. Obviously, a few exceptions have been noted, including Biting Wind.
