assuming there are more trees around,
i hold my sword in my right hand, with my left foot and shoulder ahead of my right shoulder and right foot. i twist my torso as i bring my sword back slightly towards my head swing it diagonally right to left as my torso shifted, as my sword follows through in the diagonal motion i twist forwarm and wrist in the opponsite direction inturn changing the bladed edge of the sword back towards the clone and slash horizontally. These slashes tear the clones clothes off, i finally draw my swaord back once more behind my head and step in with my right leg performing a powerful verticle slash ripping through the clones body, i feel the resistance to the bones and flesh, much easier to cut than the tree.
I quickly turn to the second clone noticing the tree behind it. I sprint over swinging my sword in diagonal paths forming an X shape as i push forward toward the clone who would move back due to the preassure, being preshed against the tree, i swing left to right into the clones neck decapitating it and poofing it away.
