*As you move underground, I create a Lighting search dog, at long range, that can locate you thanks to your electromagnetic field... Then, as soon as you surface, the dog is already at the place you are located, and explodes in a vast blast of raiton chakra, that throws you to the mountain's wall. As this is done before you cast the Fire wall, it looses it's timing and it's never casted... Also, note that the dog is made of Nature Lighting, so it is many times faster than regular raiton...*
* The explossion has made you paralised, so you can barelly move (still on the wall) and cannot use hand seals, since your hands are still shaking because of the raiton. I then jump to an other location hiding in the cloud again, and so do my clones... Me and my clones spread through all the battlefield, and aproach you till mid range again. We are very far from each other (my clones and I), and cover a large area. Also, note that behind you there is the mountain, so you can't go any more backwards (the montain's side is 100 degrees). Also, as my raiton (actually, narute raiton) exploded, it has made the soil of the mountain unstable, so the rock in not very solid, and if you use a jutsu of grand caliber (like the previus one), it might produce an avalanche)...*
PS: The cloud jutsu covers the entire battlefield btw... You can't escape it, unless you are on a tree (aka above ground level)
