I thought it was a wind jutsu, but I didn't see anything in the description so I just went with it. My bad lol.
After reading through them all, Leaf Gust seems to stand out to me the most. This is because of its wording, it says that it can be used with a counter or free from attack and can be triggered in many ways. That in itself is saying that it has many applications, which is something I like to see in techniques.
As for a theme, I was able to pick up on two. It seemed like the techniques were either combo attacks (involving numerous punches and/or kicks and/or elbows etc), or it was one simple move done really strongly. For example, one technique is a simple lateral kick to the head to send your opponent back, but there is another that has you do three dynamic entries in row to damage your opponent. But I'm finding that all of the non-chakra using techniques fall into one or both of these categories.
The ones that stood out the most for me, besides the mentioned ones, was Leaf Strong Whirlwind and Intersection Method. That's because LSW specifically says that it makes you hard to keep up with, so I feel like that could be played around with. Intersection Method says that it breaks a bone, so if it's successful, your opponent is essentially screwed to put it bluntly.
