So I was hyped when i finally pieced together Jonin Minato and got his bond mystery only to realize I started losing way more fights than I did with a weird Hokage Minato/Suit Sai team i was using before it. After losing basically any fight where I didn't have a clear advantage I started having a lot of questions as to what should I do next or start working towards like:

Should I even be trying to use Jonin minato with 90k power 7k ini &

What ninjas should I work towards or save coupons for/should I even go for ninjas over power

Looking around 5kage Madara seems to be the best ninja to go with Jonin Minato but thats where i'm lost mostly. I'm about 30 frags in for some ninja that can go with Minato like Kisame, Shishui, and Kushina with only 10 madara frags. Do I ignore Madara and keep going for Kisame since they have similar mysteries? Should I even keep piecing these ninja together over power items in events or should I save coupons to outright buy a ninja? I like the idea of using Minato long term so if i were to save coupons what ninja should I be looking at? 5kage Madara is probably the answer however some future ninja like Edo Itachi seems interesting with Minato but would he be worth it over Madara?

If I'm counting my rares and dupes correctly then I should get my GNW super rare any day now (probably next rebate) and whatever I get will probably shape my decisions but for now I actually need lineup recommendations because even trying to climb arena is a slog when i face Shishui 99% of the time:
