play it similar to that of a regular Mordekaiser, the only difference is that you always want to change the shield in HP (if you have an item that increases healing), you can assemble an item that increases healing much earlier, while in my opinion, it is not the best idea by, for example, unnecessary mana regeneration. Your goal will be to dominate the line and splitpush. If an enemy jungler comes to you then you can take a weaker person into your dimension with R and deal with them one at a time. Before you use R pull your enemy jungler to you with E, making you in the middle of your dimension and not on the edge of it.

Healing items work twice as efficiently as they should on Mordekaiser, because his w gains him a shield and than turns it into health, both get buffed by these items.

This is a good off-meta build, it has an unusual style of play which is very enjoyable, personally, I prefer to play this Mordekaiser than a regular one, I don't think you should take this build for ranked games. It increases healing, which is very cool, and allows you to turn the battle 180 ° in a few seconds with a charged W. I hope you will destroy your enemies with this build and have fun.
