1.Shadow Clone jutsu - obviously to do stuff for you, learn things extremely quickly, become a master at whatever stupid fast. Increase your productivity by like 9000, you can run a company without paying for employees just use clones.
2.FTG - have any location marked, teleport there instantly. Screw long drives home lol. (There's so much more you can do this jutsu)
3.Sage Mode - Your telling me, if I just sit still, meditate and gather energy from Nature for 5 mins, I'll get danger sensing (precognition) the ability to sense peoples chakras, ghost punches, super strength, super speed, increased durability.
**** Yes!
4.Sharingan - Obviously the sharingan is super haxed, for uchihas & non uchihas alike. The ability to read & copy movements, place people in illusions and bend them to your will, precognition as well. It's ridiculously OP and would be a super strong ability to have irl.
