Not Updated For Current Season
Mordekaiser is my favourite tank and he can - played right - dominate every game, even with nearly no ability power.
The best item build is different in every game, you have to to watch you enemys items all the time...
This build is made for a mixed enemy-team, and with it you should be able to initiate and survive every team fight. Please try it out and tell me what you think about it :)
