Most of the animations of the mystery skills are taken from the ultimate ninja storm trilogy. Anyway there's this new feature called bond skill. I suggest the ultimate team skill used in ninja storm to put in Naruto online. Obviously deidara uses it with sasori, basically it's a combination of deidara's C2 dragon and sasori's iron sand world order. As deidara's an event exclusive ninja, obviously this fits for him. Look forward for your actions.
