-Actually Minato has got three more.. speed, speed, speed... oh and one more thing... speed. That should be enough. hahaha
It's all about efficiency and coolness. pose,speed,strike,pose,speed,strike,pose... Remember Jiraiya's way of ninja.. It's not about the number of justos you learned. It's all about determination, will and the guts to never give up. Minato must have inherited that the same ninja way. And I think that's cool enough in the context of Naruto manga.
-Raikage would've died from Minato's Kunai if it wasn't for Bee rescuing him. Flawless Defense and a killer counter attack in just a split second and that's against someone who has almost equal speed and greater brute strength.
