Kagamane no Justsu- shadow imitation- Shikamaru- Its just such a "smart" jutsu, you need to actually have a strategy to use it unlike some of the other techniques. Shikamaru's father's version is just badass. Basically if you get caught in that your dead.

And Gamabunta's summoning is way under-rated. Whats a ninja gonna do against a giant frog? Nothing thats what.....damn straight.
