My understanding of how the replay system works is at the end of a game, you can manually choose to save a replay. Regardless of this, the last game is saved as _Last_Duel_Replay, which is then overwritten by any subsequent games.
Instead of just one last duel replay, have around 12 - around 4 match’s worth.
Ideally i’d like to also be able to - in the settings - toggle automatic manual save (as if I clicked save replay after every match), up to a large cap of 150~. The file names can be deckname + date or just date
Replay system otherwise works really well, I just often neglect to save the games I want. This would make it easier to share or show replays to friends
