Champion Trophy System

Ok, so I had this idea that whenever you kill a champion you haven't killed before (bots and customs don't count), then you get to keep a "trophy" from your kill. These would not have any effect or anything like that, but maybe you could get a Trophy Hunter banner and/or border and/or icon if you manage to kill every single champion.

There could be a page that let's you keep track of which champs you have killed, and maybe say how many times you've killed that champ (not really necessary though)

Some Examples: Tears of the Boy Prince The Professor's Wrench Shield of an Artisan Ice Queen Bow Hat of the Demon

This would be a cool way to show off your stripes, or better yet....

THE STRIPES YOU HAVE TORN IN THE BACKS OF THOSE WHO OPPOSE YOU
