Definitely kage bunshin it has unlimited potential in the real world as the day is never long enough trying to jam 30 hours of shit into 24 hours of the day would be easy then haha.

kage bushin, ftg, summoning jutsu, and mokuton i wouldn't need anything else.

Shadow clone jutsu and FTG would be awesome, they have unlimited potential xd
