Hello!
This is my first lol guide to a champion so do't be too harsh.Mordekaiser is a severely under-rated champ that has good potential in the jungle and can be a good addition to a team.

Mordekaiser is not currently the best pick for a jungler,but he can jungle and he is damn good at it.He has good ganking potential as he can speed himself up and an ally.He is great for doing objectives and taking towers thanks to the way he can have a pet dragon.

Pros:

High damage
Tanky
Good ganks
Good sustain and damage in jungle
Can take objectives and towers well
Good mid-late game
Works well with CC

Cons:

Low mobility
Requires to spend a bit longer in the jungle before ganking
Potato early game
CC wrecks him

Start at krugs(smite for buff),go for the chickens next,go for red buff(smite),go for crab.Then you may need to go back,if you don't need to go back tho,take blue and the rest of the other side of your jungle.

Mordekaiser works well on ganking lanes that are pushed up,this almost always results in a kill.He should get help from team mates and take early dragons to get them early towers on bot and or mid.Mordekaiser works great with any forms of CC on his team,but gets counter hard by it.
