Thanks for playing! The bit cards keeping their value is a feature. I thought would be an interesting twist to choose between "saving" your own card vs using the operand cards on enemies of course this breaks if you have none to reset the cards but really those decks were mostly for testing purposes to see what it would feel like so I found that having a good mix made the mechanic feel ok. But yeah I recommend the Standard or Operator class as the most balanced for this mechanic.
