This is my build to ap mordekaiser,here you will learn to carry with morde.
Ap Mordekaiser deals a lot of magic damage if built correctly so read steps closely and you will see why is m,ordekaiser number one :D

1.Mace of SpadesMordekaisers next attack deal more damage and hit more targets nearby.If target is alone it will deal more damage.Max this spell second.
2.Creeping Death
Mordekaiser surround himself or and ally with cloud of metal shards.It gives armor and magic ressistance and damages nearby enemies.Max this speeal at last.
3.Siphon of Destruction
Mordekaiser deal damage in front of him.This is very good spell so it should be maxed first so you can harass your enemies.
4.Chilldren of the Grave
Mordekaiser curses an enemy dealing some damage per second and if that unit dies he will gain some damage and ability power and a pet.It have 30 seconds duration.
Passive:Iron Man
http://eune.leagueoflegends.com/sites/default/files/game_data/1.0.0.134/content/spell/82-5.png Every spell that Mordekaiser use will give him damage absorpbing shield.This is one of best passives in the game it is very defensive so when you have low hp you dont need to run cause Mordekaiser es numero uno!

Flash:This is very usefull for mordekaiser when he get ganked cause he dont have any escape tools so this ois very neccesairy for him.
Ignite:This also very good spell for Mordekaiser cause this when get combined with his ultimate deal tone of damage per second so i strongly recommend taking this summoner spell.
Teleport:This is good for Morde when soloing but beware!:it have very big cooldown so use it only when its necceasary.

If you are playing renked mordekaiser is the best for solo top:D
You should get more farm as possible so you can own you opponents in late game ;)

Mordekaiser is very easy to farm with all you need to use to kill creep wave is use your q and e,or w if u want.
