Deidara also works well with Jiraiya, whom you get from the main story. You could keep your water main and use them as a support class rather than more combo/nuke potential and just let Toad Oil + Deidara bomb do the big damage.

Seems I didn't see the Jiraiya comment earlier but I stand by what I added. Use those two as the main damage for the team and then you can toy around with your fourth slot to your liking. This post was last edited by Rozuka at 2016-9-21 00:35
