If no restrictions applied:
Kamui- I can go where want with no hassle and little delay.
FTG- If there was the restriction of chakra, I could just teleport to any markers I have left in my activity spaces (so school, work, friend's places)
Multi-shadow clones- I could crash course anything in one night with five clones, than have a couple other sleep in to balance out the stress I get when releasing them.
Rasenshuriken-If I could have one landscape clearing technique with minimal to no damage to my body, it'd be this. (was going to say Susanoo, but I don't want an eye transplant in the near future)
Rasengan- And one technique for close combat.
