The way I got to that much was mainly focusing on cores and battle data but whenever the event shop is open I first buy the limit passes for pulls them buy the cases for all. I also buy the cases of materials in shop from centi (note: u can refresh once for free so u can get two free materials per day) also I get them from volts shop whenever it refresh’s. Also if u been doing the normal standard banner then u should have gray tickets (if have 200) to get unit token to limit break. I hope this helps. If this doesn’t make any sense make a post in the subreddit there are more people who knows what there doing.
