Counter Tips

Mordekaiser becomes harder to kill with his metal shield charged up. Try to kill him before he is able to regain his shield.
Don't stand near creeps when he is about to use his Siphon of Destruction - as he will be able to push the wave and deal damage against you.
Try your best not to die when you're ulted by Mordekaiser, as you will turn into a ghost and attack your own team!
A Quicksilver Sash will get rid of Mordekaiser's ultimate debuff.
