Your question reminded me of the board game "Clue"
It was Colonel Mustard in the study with the candlestick...

OT: shadow clones - for everything from chores to studying to working, so I'd be able to anything besides those things

Shadow Clone because I would just send my clone to school, and then have him come home and bring me my homework, and then he would disappear and then I would instantly know what we did that day without having to go there.

I would use Sharingan to play soccer better. I could predict where the ball moves and also where the people move. It would also be useful in fighting.
