"Good, now my method of teaching is simple. I will explain the technique to you, then I want you to perform the technique against my clone, give me at least 2 advantages and disadvantages of the technique, and also, how you would use it in battle. State these clearly, so it makes it easy. Anyway, let us begin with the first technique.
By using your chakra, you will induce an illusion on the opponent, and cause them to see the terrain change, based on your preference. The terrain only though. This means you can change the terrain from a desert, to a forest for example, or more simpler ones, like create a wall before the opponent, or a tree. Whatever is created is illusionary, and is only for fooling the opponent. The technique has a bunch of smart uses, if you are creative, but don't go beyond the limit of the technique, only the terrain can be changed, and nothing to drastic either. The more subtle the change, the more effective it would be in battle. Use it against my clone, and explain it in detail as you do so, plus add the other things I said I require from you per performance of a technique."
