survival mode.

randomly choen champion based on a draft like system , but instead of choosing top,mid,bot,etc you would choose tank or fighter or marksmen.

you would get 500 gold starting and over time the amount of monsters there size and hp/atk dmg would scale.

you would have access to the bildg water map shop that has turrets and stuff . and you could purchase defences.

basicly riots ver of zombies.

once you die your done. and your get a scaling ip/exp based on how long you lived and how much you killed.
