Okay, I begin by sending a large amount of my earth chakra into the ground in front of me. I use it to take control of a piece of earth about 2 metres squared, which I manipulate with chakra to suddenly drop downward 20 metres underground. As I do this I manipulate the same sized area of earth under my feet to rise upwards 20 metres above the ground.
The pillar that I raised would be used to gain a vantage point over your opponent, as well as to get you out of a certain swampy situation if needed. The area that I dropped would be used to trap my opponent in a deep hole that I could bombard with fire/wind combinations or flood it with water/lightning combinations. If I drop a large enough area it would also be able to hold a fair amount of water from an opponents jutsu.
