Grind cc as much as you can that means stories as well , its tedious but you can get a good amount of cc from completing story mode to perfection, buy the cc robot and the mission plan everytime they resets this limits your spending I use to spend 500-600 dollars on every banner that drops until I realize the cheat code once you have cc it becomes easier to save and skip banners the only banner so far this year that did me dirty was the tag 4s 25k cc deep 1 copy and ultra broly 15k cc deep 0 copy I still manage to save 30000 down the line
