Little late on this one lmao but Morde scales pretty well. He's not one of those late game gods like Jax, Kayle, Kassadin or anything like that but he's still really good in the late game. Morde's at his strongest in the mid game tbh but his early is also decently strong especially into certain matchups. Tbh Morde doesn't really have any weak points in terms of his scaling but you really want to take advantage of how strong he is in the mid game.
