It appears that sometimes, card rewarded when wining games do not stay in my collection. first time, it happened with Black Market Tycoon from New Capenna, and now, it appears that the last card I can't find no more in my collection is All will be one from the set with the same name.
Am I the only one for whom this kind of things happens? I am now keeping track of what rares and mythics I win to avoid becoming crazy thinking I won cards that do not stay in my collection.
