Low Elo Morde Kind of hard to say but I wouldn't risk it and I would ban him. Thing is in lower elo most players will probably not know exactly how to handle playing against morekaiser (kiting him and not full on engaging unless you can 100->0 him) So it's more likely that a mordekaiser even if not played to his full potential will win lane in lower elo, especially if paired with a support like blitzcrank, nautilus, leona (beefy melee cc filled support tanks basically)
