There are 3 unused Jutsu

[XY iNVeRSe]

creation of all things
minato's jutsu (pretty obvious what it is)
full power of the rinnegan (Madara's or hagoromo's)
madara's ms techs
izuna's ms techs
hashi's binding jutsu. (Probably just absorbing SM back)

 

[Eternal Mangekyo Sojobo]

Sasuke's unknown summon he talked about with Juugo to counter the Juubi bijuudamas.
Madara & Hashirama full arsenals .

 

[Your Creepy Stalker]

Konan was prepping a new large jutsu before Obito grabbed her throat T.T

Like the Lion thing, we saw that in the anime. It was kinda dissapointing.

 

[Mongekyou Uchiha]

We did saw rinnegan, nagato use the full power to summon the dragon lightining thing

 

[Zorø]

Yhhhh I know dawg.....
