This certainly isn't bad, but I think the slow on the shield is too much, unless it only applies on additional damage. Otherwise you're basically giving Mordekaiser (or whoever he puts the shield on) a 6-second permaslow with no means of escape beyond burning flash or using their mobility spells (if any). I also have to admit, his original E always annoyed me by basically being an insta-hit with no signs of activation nor any means of avoiding it besides range. If your version of his E works in the same manner, than I have a problem with a widespread nigh-undodgeable slow. In addition, I'm not entirely sure of the idea of him having an undodgeable Bork and DFG is very fair either. On the positive side though, I do like how his E toggles and costs health, giving a very "cost vs reward" feel.

So again, while it's not bad (and certainly a push in the right direction), I think you could stand to do more. Quite a bit more, if I were to be honest. He's an undead abomination within a suit of armor, with dominion over metal and death. When doing kit reworks or full reworks Riot likes to tear a champion down to their core, and work back up from their most central themes. Try looking at it from that perspective; what to you are Mordekaiser's most core aspects and central themes? What makes him who (or what) he is in your eyes?
