while I don't love having to get new cards for rotating formats, they're the only viable solution to power creep I've ever seen, and for me at least the overall 'feel' is infinitely preferable to that of the eternal, been-solved-for-years formats. (at least in MTG, I never really got into hearthstone).
i sorta understand why MTG does it but in digital formats, cards can be nerfed immediately at any time if they're too imbalanced, so it should be a lot easier to preserve balance without expiring cards... plus, i'm not really opposed to the idea of a game being "complete". the need to continually be selling new cards is just capitalism making games worse
