This is my first build so... Please have mercy! (╥﹏╥).
As a Mordekaiser, your job is to bring terror and destruction to the land. Thanks to the new E from Mordekaiser, you are able to grab your enemies and take them into your range, and once inside, they will unlikely come out unscathed. Once you get the Rylai, they will be able to save themselves only if you allow them to do it !!

Furthermore, the magical penetration of E is something so broken as to make you a Darius AP !!! (╯✧∇✧) ╯
His R is your battlefield. Can you turn any fight into a 1v1, where you steal a percentage of your opponent's most important stats.



But let's start to see how to play with Mordekaiser (in my own way). Before level 3 it is not recommended to engage, since your w gives an excellent shield and sustain. The combo obviously is E + Q + AA + W etc., once you learn the timing you will be able to hit your enemy with Q while being pulled from the E (like Aatrox).
Thanks to your E you can also push your enemies away from you, aiming at the minimum towards the opposite direction to the enemy. Passive instead is your workhorse. A simple combo activates it, giving you movement speed and area damage as long as you're in combat, combined with the rylai and Liandry, even Cho'gath would tremble from fear.


The late game is self-contained, if you played well, you can spread the terror worthy of an ancient tyrant, if you are behind, you are the classic skeleton knight you face in the tutorials.
