Alchemy: Phyrexia packs giving bonus commons instead of wild cards
I have had this problem before, and I think I was compensated for it, but I thought it was fixed. I am getting additional copes of cards I already have 4x of (in the correct printing) with packs that are not directly that set's cards. In this case, I opened an Alchemy: Phyrexia pack and got a Crawling Chorus (from ONE). I know that I was playing a constructed deck with 4x of the card, and I know how many wild cards I have, and the number of wild cards did not go up, and the collection still says that I have 4.
I have investigated further, and have found that uncommon duplicates go towards vault progress. My mistake.
