I have been having a lot of sucess with that build even before the AP itemization rework:

- -  -  -  -

The idea is to maximize cooldown reduction and stack a lot of flat magic penetration. You will be tanky while still dealing great amounts of damage. Enemies can't focus you because you can survive pretty well during teamfights. This build works because Mordekaiser has insane base damage and his shield can be used in tandem with items that give resistances and AP.

You can replace Ionian Boots for for even more magic penetration or  for protection against CC, but I would only recommend to do so if you have cooldown reduction runes to compensate. You can replace Zhonya with if the enemy team has a dangerous fed ADC or is auto-attack heavy. You can replace Spirit Visage or Abyssal Scepter with if the enemy team is not AP heavy, and if the enemy team has no AP at all, you can replace both with Rylai and Zhonya.

and are not necessary and I would not recommend them. Even though they boost your damage, they do nothing to help in your tankyness. can be an option due to the magic penetration working well against any tanky target, but again, it gives no tankyness at all.
