I always say that I’m not the person to ask about team building or event efficiency because I mostly just throw the strongest cards I have together that are the right attribute and maybe link to each other, so that’s…really all the advice I can give…

In terms of points, getting any of the gacha cards (even a single copy of one of the 3*s) gets a lot of extra bonus points, and my teams can generally beat the expert+ boss in one or two tries so what I tend to do is just build up a lot of event tickets and then use any stocked up skip tickets I have on the expert+ boss.

I’ll throw in a picture of the team I used to beat the expert+ boss in a single try if that helps!
