If you are number 50 in your clan and you want to move closer to the "top" you have 3 options. Option 1: grow your stats faster than the other players in your clan. Becoming stronger than them will raise your clan ranking. Option 2: Become an admin and kick all the stronger players. Presto. You'll be #1 pretty damn quick. Option 3. Make your own clan and let no one else in.
