League Roulette

Play this with a full team of friends.

Pick a lane (Top, Mid, Jungle, or Bot). Have everyone count up their champions in the "Available" tab. Each person will pick a number for the person below them, the last person will pick for the party leader. In the same way, everyone will pick each other's roles (Marksman, Support, Tank, etc). The number picked for you is the number champion that you must play in that lane/jungle, and you must build as that role.

Tell me of some of the combinations you had to tough through in the comments!
