Any suggestions for those teams? I'm thinking of changing things up for my water main, who's teaming with 6P Naruto, normal Roshi and 7S Killer Bee atm.

No plans to post my collection right now because 1, I'm not at home now so I can't. 2, I've been amassing coupons for some time now, so you can go ahead and assume that I can buy ninjas like Kisame, Minato, etc. if needed. Just no premium ingots only ninja like 10T Madara or something.

Alternatively, I could change main if said main has better synergy with my current teammates.

You say I could try checking my own server's ranking to find examples, but sadly there aren't many top water mains in my server.
