Here's a few tips in ranked : have a backup healer/reviver, got aoe attack, can do auto and manual barrrier if needed; and debuff for screwing enemy teams (looking at you watermain equips with poison tai)
Here's a few team using your own ninja rooster : -
Tsunade(sannin) - Guy - Kage Gaara GNW Sai - x - x x - x - x
Tobi - Torune - x Itachi - Kabuto - x x - x - x
hope it helps ^^
