It'd be nice to be able to see how many I have of each level of the 'completed' ones so I can plan for keeping one or two max copies for income purposes
Previously, when you submitted a MAX card, all cards of that species were automatically sold to prevent duplicates clogging up your deck and making later merges harder. Now, once you submit a MAX card, that species is considered "collected" and marked as such in the Deck view for easy selling. You can hang on to duplicates to generate more points or sell them to make room for easier merging. Your choice!
