I've made Mordekaiser work, while having 16 wins and 3 loses with him so far

It's hilarious, becouse a day ago, I've made a post about Mordekaiser being to weak, wich received a lot of attention.
I don't know why, but I thought that I lost at least half of my games with Mordekaiser, and I've just checked my lolking. It probably wouldn't work so well against higher then diamond players. I played him about 70% of times in the jungle and 30% top, mid - about 1/3 I lose my lane.
