The above team might be good at the start, but will not fare well in later levels. Your main bet here is kidomaru shield and kimimaru passive. Opponent can dps down your kidomaru real fast, then work through others.
Use a team that can kill fast. Above said team can do amazing sometimes in arena (Kidomaru can become a wall there is you can manage to keep him alive long enough).
Curse team can be pretty anooying and strong if you can manage to keep them alive, but that's their weakness too.
