Can't rely on one ninja to do the work. Plenty of common ninjas can drop your flower guard e.g., Masked Man, Han, Anbu Itachi soon. Even ninjas as dominate as Edo Tensei Deidara need support. Many, if not most, PVP teams have a ninja that can clear your clones with one mystery; unless you're more powerful than they are. If they target your main with or without flower guard, there's no one there to save her.

That's just my opinion though.
