ok maybe its hard for a jungler to help you with a gank cause you push your enemy under his tower....
BUT who care?
most time you dont need the help of your jungler cause you´re mordekaiser master of pain and pushing!
so notice push them hard, dont wait for last hits! sure you make them too, but push it!
while your enemy is crying under his tower and defeting your minions, you bash the next ghost´s and be back on lane before he can push back to mid...
activate your dmg shield when you want to push and your opponent will step back!
when your quick you can deal dmg to him while he is under his tower, with your "E" and be out of tower range before tower can attack you!
when your enemy is under 50% life and waits under his tower and your skills are ready load "Q" and "W" Flash in give him "Ingite" "E" and Ulti "R"
go out of tower range and let your Ulti Pet attak and tank his own tower!
or if minions there let them tank ^^

be carefull of enemy jungler´s!
take 2 wards with you and place them in the middle bushe´s ... you know which i mean ;)

for me hard opponents are Corki, Malzahar, Zyrra


BTW many guys playing mordekaiser, always say buy rylai´s crystal scapter...
DONT DO IT !
its a nice life pool but the slow effects only 15% and is not so usefull!
you wanna deal dmg? then take Lich Bane and Liandry's Torment !
a full AP Rune Build may be funny in the early game but in mid and late game you rule the **** out of your enemys with this setup!
