This is just a healing team based on taijutsu and acupuncture. It's countered by burning teams with ignition and people in the front row who can interrupt Hinata. Neji or Iruka can stop her from casting her shield easily and then any taijutsu team can finish her off. Without Hinata tanking, Gai is extremely squishy and Kabuto/Main aren't going to survive well alone.
I think it does well only because Hinata is in the top row and clones tank the middle row.
Plus if you're in the top rankings you have much better refining stats than other players and tend to go first a lot or crit/get crit less, combo/get less comboed.
