1This one I use most frequently, you basically exploit the Instant Rise technique ( Block + Joystick + Shuriken ) to cancel a shuriken into anything,
this trick only works with Sasori for some reason...
I always use shuriken + jutsu in order to make the jutsu hit more frequently, especially when they're charging their chakra, it works miracles. You can also cancel shuriken into throws to make them unsubbable or at least pin down the opponent.
If you didn't get what I mean, it's ( Block + Joystick + Shuriken ) + ( Jutsu/throw )
2The Jutsu followup, you can hit your enemy with an additional Jutsu if you succesfully finish your neutral combo or throw, since they're on the ground. Although you'd have to time it really well after a throw, because of lag.
3Combo cancel into Ultimate, basically your neutral combo, press the attack button three times, then use NMC to cancel into ultimate, works surprisingly well.
4Awakening routine, whenever you awaken with Sasori, there's a specific routine that can be very useful against people who spam shuriken or run away, its only weakness is people who spam c.dash.
Basically, you ( Jump + attack + c.dash ) to make sure the air attack hits, if the opponent decides to c.dash you this routine will get very annoying to do, so counter with c.shuriken, people substitute this alot.
