Sky Force Anniversary - Trophy - House Of Cards
Showing where (Stage & location), how (difficulty), and when (Medals completed) that I got last 4 Cards needed.
I think it is random but higher chance to drop on Stage where you have Medals left to complete. Possibly you need to have Insane difficulty unlocked on all Stages before last of cards will drop.
Lastly, I don't recall getting more than two cards any single day. For instance, the 4 cards shown are from two consecutive days playing enough to complete all Stages once on either Nightmare or Insane.
Looks like the effect of Night Camouflage card is to give your default Red Plane a new look. Not sure if there is any other benefit.
