Hello, I'm pretty new to this game and this is my first guide so sorry if some information is incorrect. But, I wanted to create a Mordekaiser Guide as he is my main and the champ I learnt the game on.

Here's some extra tips/info for playing Mordeakaiser:

Laning phase:

EARLY: Levels 1-6 are your weak point. Mordekaiser's early game isnt good, so this is where the enemy top will try and take advantage of you. Generally you don't want to go for trades before 6, play safe and ideally freeze wave undertower. This means last hitting only, you can last hit multiple minions with your abilities but I'd suggest just autoattacking since you don't want to accidentally shove out the wave. Keeping the wave frozen protects you from ganks and bad trades, so its your best option pre-6.

MID: Mid game (about 15-30 minutes) you want to abuse a side lane. Mordekaiser can be good in team fights but is best in small skirmishes and 1v1s, even though he doesn't destroy towers too well he has enough dueling power to put enough pressure on the map for the enemey team to send 2-3 players after you. If you have ultimate then you can go for a 1v2 but generally you want to waste as much of their time as possible so your team can go for major objectives like dragons.

LATE GAME: You want to go for team fights late game, but remember to always have ulti up otherwise you'll lose the fight. Make sure to ult the enemey backline carry, i see a lot of Mordekaiser players ulting the support just because its a free kill, but this usally loses a team fight and intern, could lead to a lost game. If you can't 1v1 the carry, don't worry, try to waste as much time as possible in the death realm. Its more important that they aren't in the team fight, and the longer you can stall for the longer your team has to fight the 4v4 (which they can usally win when the enemey doesnt have a major carry avaliable). Then once death realm is over, the enemey you ulted dies in a 1v5 or 1v4 pretty easiley. Other than team fights you just want to go for objectives and make picks on out of position opponents.

Quinn nerf will have no effect on her match-up into Mordekaiser, her W is not the reason why she's dangerous into Morde.

Teemo buff doesn't really change much for Mordekaiser's match-up into him. His Q will be more annoying than before but that's not really relevant.

Goredrinker nerf is an indirect buff to Mordekaiser as some of the harder matchups like Fiora become weaker because of the changes.

Conqueror nerf makes it less dominant of a keystone overall, however as Mordekaiser you never really had trouble keeping the stacks. The less adaptive force coming from Conqueror will hurt Mordekaiser's viability, however, but not by much. You should always run this keystone into most matchups.

Health shard's buff makes it a good option into easier matchups for that scaling HP bonus, or into mixed damage matchups.

Although the domination tree secondary wasn't really viable on Mordekaiser anyway, the reduced omnivamp on ravenous hydra basically makes it completely inferior to the resolve tree secondary.
