Best way to get stars after all missions done?

[ZOMBIEKILLS_128]

I am at 252 and have all missions done. I am not doing the boss voucher so what should I do for 48 stars?

Play rs, events, br. They all give you a star per game or so

If you want to play offline play conquest.
If you did the tenth inning already, do the run it back map.
Conquest is 1 star game
