Hi! This is my first guide, so yeah. Hi! :V

If you're reading this, you've probably just tried a 5v5 build on Treeline and gotten wrecked. Or you're just curious about how the rules are different in Treeline. But one thing is true. Mordekaiser doesn't have to and probably shouldn't be built like he's playing in a 5. The food chain is entirely different in 3v3, and you need to change your build to reflect that. For example, Jax isn't complete garbage in 3v3 (He actually does quite well!). Let's go into detail below.

You'll want to build typical Mordekaiser runes. Mord always can use Greater Mark of Magic Penetration, and Greater Seal of Evasion is needed as you'll mostly face cheap melee champs that will shred you if you don't have something to alleviate that. And you'll need Greater Glyph of Cooldown Reduction because the faster you can spam your abilities, the more shield you can generate. And shield is what allows you to charge into a 3 on 1 and not take a lick of damage (given that you're in enemy creeps). I've done it before! Lastly, though I won't explicitly tell you to do this, I go Greater Quintessence of Health with Mordekaiser. Though you can go Greater Quintessence of Cooldown Reduction, Greater Quintessence of Revival, or even Greater Quintessence of Gold for all I care. This is the one where you really can do anything. However, like I said before, I personally use Greater Quintessence of Health. The early game health can make the difference between an first blood gank, or a first blood reverse gank. :D

OMG U DIDNT USE GHOST U NUB!!1111oneoen

Yeah. I didn't. I personally use Exhaust and Ignite on Mordekaiser in 3v3. Ignite should be obvious. If it's not, I'll explain. Your Children of the Grave deals damage over time, and so does Ignite. Also, typically, you see Tryndamere in 3v3's. It's almost a law of nature. If you've got Ignite and your Children of the Grave, you can shut Tryndamere down. What makes Tryndamere so boss is that he can rush in, and then use his Undying Rage to avoid death, Spinning Slash out of the fight, and then use Bloodlust to heal up. So what do you do to stop this? Ignite him as late into his Undying Rage as you can (I believe it lasts 5 seconds), then use your Children of the Grave on him. It's a guaranteed kill nearly every time. And that's how we shut down Tryndamere!

Now Exhaust? Typically with brusiers you roll Ghost, mostly for when your team gets overrun and you say to them "Later dude!". Well, Exhaust can help you escape too. Also, nearly every time the entire enemy team will be made up of melee autoattackers like Master Yi, Tryndamere, or Jax. This allows you not only to escape from them, but also to turn the tides in a 1v1 fight with Jax or Master Yi. Also you can put it on Tryndamere a couple of seconds after he uses Undying Rage so that you can Ignite him that much later.

But what if we don't want to use one of the spells? I would suggest Revive. Sure, it's a garbage summoner spell. On Summoner's Rift, that is. But in 3v3's, for some reason, Aces really , really, really hurt. Revive solves this problem. BUT YOU MUST SAVE IT UNTIL YOU REALLY NEED IT. It's on a nearly 9 minute cooldown. So say you get aced, and they charge one of your inhibitor turrets. This is the perfect time to use Revive. Revive in, smash some face in, and repel the turret attack. Possibly even scoring a kill to boot!

Basically, you want to level up Siphon of Destruction first, putting points into Creeping Death when you have to, and putting one point into Mace of Spades. Level Children of the Grave when you can.

There's a big dispute among Mordekaiser players about which to level up. Mace of Spades or Siphon of Destruction. For this build, I'd recommend Siphon of Destruction as you're building AP as your damage stat and nothing else. However, if you like to build up Mace of Spades first, I'd suggest replacing the AP items with Hextech Gunblades instead. That way they provide both the AP and AD you need to make Mace of Spades effective.

I usually don't try to get the early game gank as Mordekaiser Mordekaiser's one of those champs you have to play really safe with early game. At least until level 3 or 4. Basically, while watching the minimap, you'll want to push as hard as you can without taking much damage. If the bottom lane is mia, back off a bit. When you get about level 12, you'll want to switch with the person that could use the gold of a solo lane. From this point on, it's time to move between lanes, either pushing towers, or ganking. Hopefully you've got teammates that fit into this strategy.

If you don't? It's okay, you're Mordekaiser! :V

Now this is where I'm going to catch hell at. Building Mordekaiser with Warmog's Armor... In fact, Rushing it. But just trust me on this. The health is way too good to pass up. As long as you build armor alongside it, you'll be fine. Also, the earlier you get Warmog's Armor, the better. It snowballs with kills, up to 10 kills. And this early in the game, the massive amount of health you have will be just too much for some champions. And don't worry, chances are, No one will be building Madred's Bloodrazor this early anyway.

Next thing you'll want to get is some boots. Sorceror's boots. If they try to build MR, you'll just shred through it between your runes and boots. Getting boots brings you up to just under 30 Magic Penetration, which is about enough to counter ALL of most champions' Magic Resist.

Now it's time for more health... and Armor! Sunfire Aegis is always a good item for Mordekaiser against mostly Physical champs. Not only does it give him health, but it gives him an even greater AoE Presence. In the rare occasion that you're facing a mostly magic team, I'd change this to a Force of Nature.

Rabadon's Deathcap!? Yes. Despite Mordekaiser's less than stellar AP rates, pumping AP into him can make quite a difference. Using this alongside Mejai's Soulstealer, you can hit well over 450 AP. I remember dealing just under half an opponents HP with Children of the Grave. Pretty much if they're under half health, you can kill them without any effort. If you're doing well when it comes time for this, I'd get Mejai's Soulstealer and replace Abyssal Mask with Rabadon's Deathcap.

Rylai's. Tank tank tank. Oh and AP.

And lastly Abyssal Sceptre. Not only will it give you magic resist and AP, but it will also cut reduce magic resist of other champions. So if your teammates are lacking in magic pen, they'll still cut through that magic resist.


Oh, and remember what I said about if you want to max Q first? Though I don't recommend it, I'd replace Rylai's, Rabadon's, and Abyssal with Gunblades.

Well, I hope you enjoyed my guide. Hope I didn't bore you to death. If you like it, be sure to show so in the ratings. Not that I'm a rating ***** or anything, but why not let people know about this? :D

OH, and let me throw some pros and cons out there.


PROS:
A really, really hard target.
Enemies can either focus you and get shredded by the carries, or focus your carries and get shredded by you. I know, right? :P
Deals respectable damage to be this tanky.
Can farm like a beast.
Great in sloped fights as long as enemy creeps are around
Children of the Grave can turn a 3v3 into a 4v2.
Insane AoE presence. Don't enter a teamfight without one!
Can turn a 1 on 3 gank in their favor around, acing entire teams by himself (I've done it before)
Mordekaiser's size and pushing ability has a psychological effect on people. It's true!

CONS:
While Mordekaiser can do a lot of things, he does them worse than a champ designed solely to do said things.
If you get caught without Iron Man built up, you're toast. Even if it takes an hour to cut through your health.
Absolutely needs kills to be effective mid and late.
Can't push as well as Sivir
Can't tank as well as Shen or Rammus
Can't nuke as well as Annie
