I propose to implement series for CFTs. This feature could be in the form of waves of updates, with new CFT designs added from time to time but grouped each time. Each set of CFTs could have a different little theme.

So the current series could be called something like "first edition" and then later a new series/update could appear simply adding new elements like new hair, clothing, etc. on top of what already exists. Instead of adding new items randomly and silently.

In addition to that, they could also see special series, separate from the overall series, with exclusive designs that will only be available in them. These series could be available for a limited time or be reserved for special occasions.
(But this is already planned from what I have seen)

Users could see the series of each CFT in the information with why not the total number of cards in that series.

To summarize:
- The main branch with occasional additions of new elements per group presented as small series/updates.
- Special limited time series and exclusive cards
