League is like rock, paper, scissors.

More accurately Paper & Scissors.

So you have scissors on one side that beat paper on other side.

Or you have paper on one side that is getting beaten by scissors on the other side.

Sometimes it's both are paper but one side is drawing on paper while the other side is cutting the other guy with a paper.

Or it's both scissors in which they both swordfight with scissors and the better one wins, or the one with longer/sharper scissors....

etc.
