Not to mention that sometimes the login card contains only flower gems so for those ten days you'll get one per day guaranteed just for logging in, but you'd have to have played for longer than two weeks to find that out. What's the rush? 12-3 is one of the best farming maps in the game, and until last week it was just two maps away from endgame. You say you need better girls...have you upgraded the ones you have? Have you evolved them? Have you maxed their affection? Have you upgraded their equipment? Given them ANY equipment? All of these things are within your reach if you've gotten to 12-3, but it takes time to work on it. I absolutely promise you that any map in the game is able to be cleared with 3* and 4* girls if you put in the effort required to help them achieve their potential. I still have 3* girls in my teams who outclass some of my 5*s, and though they are evolved, they are still really far away from max level.
