Well, you read it well, only one can be the winner. Try to own or kill the person who posts above you, by using an original (anime) way.
For example: mr. X posted above me, so I use Rubber Band (One Piece) to own him. Off course, mr. X has some great way to somehow survive this, and then uses his vectors (Elfen lied) to slice me in 2.
This was just an example. Now, I'm owning the previous post (which is nothing), by just being here, so he can no longer exist ^. Well, try your best shot at me.......
