Same has happened to me. I grinded out a bunch of starter decks years ago which now show little to no cards owned. After a search this is pretty prevalent and affects cards bought with gems too. Glad I found this before I pulled the trigger on getting/using gems. Not gonna pay for pixels, especially when they'll just randomly disappear. I doubt they'll fix it after apparently 3 years either, despite being a major flaw to this kind of a game
