I think cards being deleted from collections is a feature not a bug. WOTC does this intentionally to keep certain cards from affecting the metagame too much. Similar to how an algorithm is used to determine opponents depending on your win rate, cards in your deck, etc. Its not totally random. They do this to level the playing field for new players. I think WOTC are opening themselves up to liability. If we've paid for cards aren't they technically our property? They cant just delete them, right?
