Play Video Morde's 2nd favorite song. I personally don't like it, but it's me. I'm the not HEAVY and METAL type, like Morde. The song is very close to mace of spades. Listen to it while reading.

Mordekaiser's "Lore", by Riot Games
During the most recent winter solstice - when no other night during the year is longer - a being like no other emerged from the forgotten alleyways of Noxus. Standing eight feet tall, and concealed within a razor-sharp armored shell, he came to be known only as Mordekaiser. The nature of what lies beneath his metallic carapace is a popular subject of speculation. Many allege that he is a mortal man with a heart that has hardened to iron. Others insist that he is a dark specimen of the undead. But there are some who whisper warnings that he is merely a foreshadowing of something terrible and unprecedented yet to come. Despite the public conjecture and curiosity, none have discovered what lies beneath his alloyed exterior. What is known is this: Mordekaiser arrived unannounced at the Institute one day and, with a rasp that crept ice up the spines of all within earshot, requested to join the League of Legends.

Upon glimpsing his fearful visage, most keep their distance, fortunately unaware that his touch bears a sinister scourge. Those who stumble within his grasp fall victim to incurable maladies. In fact, Mordeakiser seems mystically attuned to sickness, as if it feeds and comprises part of his chilling essence. He now stalks the slums of Noxus, drawn to the plague-ridden and diseased. However, there is something in his clever tactics, something in his noble stance, and something in the tone of his unearthly commands that has led many to believe that Mordekaiser is more than just a foot soldier. Some see the distinguishing characteristics of a general. While many have learned to accept the evidence of this unsettling possibility, a lingering questions keeps them wary at the witching hour: if Mordekaiser is a general, what nightmarish legion lurks at his command?

''The common perception is that the encompassing armor protects him, I fear that - for the fragile time being - it actually protects us.'' - Rozuel Fecirem, Arch Adjudicator, noted in Mordekaiser's eligibility evaluation

Mordekaiser's REAL LORE (HIGHLY ADVISED AGAINST BUT RECOMMENDED TO READ)
There once was a kid named Tommy Mordoncio. He was an extremely rich boy, and lived a spoiled life. But one day, his family was robbed of all their possessions while away on top of Mount Everest (dropped off at the top, of course. They did not climb it.) Tommy was then abandoned by his parents and lived on the streets. A magician found him and took him in. She taught him, over 20 years, magic. The magician's name was Le Magicien Blanc(google translate, French>English. Ironic, amirite?). She taught him many things. She cast a spell on him, making him 8 feet tall. Then she gave him a large suit of armor and a big spiky mace. One day she asked him, "Would you like to leave this world?" "YEAH!" "Well, hop on my incredibly fake broomstick!" And she flew him to Runeterra, where he was greeted by summoners. He gave himself a nickname, Mordekaiser. He passed Judgment and now is a reigning champion on the Fields of Justice. One day he will wreak havoc on all thieves. He is doing so at the time, fighting Shaco, Evelynn, Teemo, Twitch, and Akali. He's coming for you, burglar.

"One day all burglars will die. And one day I may get my first kiss. And one day I want a hamburger! SO GET ME A HAMBURGER OR DIE." -Mordekaiser

So, I've played against a ****load of Mordekaisers. And I normally play offtanks, so it's not a problem. I know how they work. Not much damage, high survivability. Then, I just watched top get double wrecked by a Mordekaiser. So I decided to buy him. When I started playing him, I was absolute ****. So I put him down for a while. I came back to him later. I've looked at the 3 top-rated builds and thought those were good ways to play/build him.
I was right, but not to degrade any of those, I just couldn't follow how they played. I was too reckless and I wander randomly about the map when they're all mia. So, I improvised, and made a new build. I present to you, revamped, epic Mordekaiser. Who can 1v1, 1v2, 1v3, and even in some cases 1v4. Who can take down a team fight and get a penta kill without ksing. Who can rape squishy noobs like Twitch.

Pros
+Great at pushing/taking towers
+High damage and high surviability late game, unlike others like Lee Sin, who have to sacrifice one for the other
+Hybrid-like, can do more than one thing
+Ghost of their carry, allowing you to take down the teamfight
+%Health steal with ult
+AoE skills
+Completely tears squishies apart
+Great farming, usually about 200 minions per 30 minute game if done correctly
+Eight feet tall, will scare enemies away
+Uses health as a resource so you won't have to worry about ability spam.
+Can beat most solo tops like Cho'Gath and can easily beat 1v2 ranged. Best solo top IMO.
+Deceptively strong, like LeBlanc
+High versatility
+Breaks fourth wall
Cons
-Is usually built full tank with no damage]
-Unfarmed Morde is a sad Morde.
-Takes some skill to play
-Hard to control ghost, but if you can, it pays off.

+/- Snowballer.

9-0-21 for Mordekaiser.

Offense tree is for AD-Dps, Defense tree isn't worth it imo. 48 health, 6 armor and mr, 2% dodge chance, 2 less damage from minions, 2 less physical damage, 4% damage reduction. It's so minimal, so 21 in Utility is sooo much better. Let's see what we get from Utility.
Haste , Extra duration and MS on Ghost.
Perseverance, Extra health regen is bleh, but nothing else to put points in.
Good Hands , 10% less death time.
Awareness , 5% more exp. Lets you solo top more effectively.
Utility Mastery , 30% buff duration. That equals 45 seconds more on Red/Blue buff, 1 minute 12 seconds more on Nashor. I think 15 seconds on the buffs in TT, and like 1:30 on dragon?
Greed , Not much, but again, nothing else to put points in.
Quickness , One of the best masteries. Gives 9 movement speed, which may not seem like a lot, but it can be the difference between a successful gank or getaway.
Intelligence , 6% cdr. Great, moving on.
Presence of the Master . Best mastery in the game, giving you 15% cdr on your summoner spells.

My summoner spells are standard Mordekaiser spells. Ghost for extra movement speed to catch up to someone or run away, and Ignite for the added DoT with his ult.
SO MANY Mordekaisers take Teleport/ Ignite. And I'm like wtf? No getaway. No Mordekaiser (except for the one I introduced in the beginning) was actually a good one with those.
Actually, I've gone up against a lot of mirrors. They all sucked because of wrong items/spells.

Your summoner spells shouldn't really be changed much. But here are some good picks.

Viable Summoner Spells

(order from most to least recommended viable picks)

Flash, used to get out of sticky situations or flash up and deal the killing blow.
Exhaust, used to shut someone down at a turret or 1v1. It can also be used as viable CC.
Cleanse, for those CC heavy teams.
Teleport. I know I just flamed on this, but if you really want to get around like that, take it instead of Ghost. You're Mordekaiser, and your minion kills should be at least 60 by 15 minutes. Apparently it's used for getting to towers to farm, or getting back to lane faster(to farm more). But you really don't need to b until lvl 10 if you play right. :P I once went a game where I went b once. 30 minutes in, "Woooow, noob Morde only has a regrowth." BAM! Force of Nature, 2 Hextech Gunblades, and Sorcerer's Shoes. We won. Carry Morde :D

Less Viable Picks

Fortify, more of a meh spell for Mordekaiser. Good if you want to build pure tank, but this is an offtank build.
People are going to hate me for this, but Heal is also a viable pick. Used for a lot of things, like early game bait, towerdiving, stuff like that. Falls off late game, which is why it's not as viable as other summoner spells.

Really Not Viable Picks

Smite, although Jungle Mordekaiser is slightly semi-semi-viable(which means its not viable) and has a fast lvl 5 clear time (about 5:10) his ganks are lackluster. Red buff and pure damage are his only options for a gank.
Clairvoyance, used more for supports.
Rally, Yay first blood banner!- no.
Revive, you shouldn't be dying often enough to use this.
Clarity. This is a great summoner spell on Morde. It banishes all of his mana problems! If you're new to Morde, take this! No, but seriously, if you don't know why this is at the bottom of the list... just take it.
Promote! This is actually by far the best summoner spell-oh wait, it was removed. Mmkay, moving on.

So in Unforgiven's guide, he stressed on runes because Morde has a terrible early game. Believe me, if early game is like lvl 1-2, then he does.. But his runes are fine. So let's go with those. Greater Mark of Magic Penetration, magic pen for obvious reasons.
Greater Seal of Armor, flat armor for early game.
Greater Glyph of Magic Resist, same as seals, except these are flat MR.
Greater Quintessence of Health, Flat HP for sustainability.
You can also take these runes if you're not comfortable with the above. However, the rune setup is pretty cheap for an entire rune page, so it is recommended.
Greater Seal of Vitality, a solid pick for late game scaling. Though your late game is in 25-30 mins because that's when you hit lvl 18 ;D
Greater Glyph of Scaling Ability Power, make your spells hit just a little harder.
Greater Glyph of Scaling Magic Resist, MR/lvl instead of flat MR is also fine.
Greater Quintessence of Movement Speed, if you feel that 324 Movement Speed is slow, then like 340 is great. Great. Morde's already extremely fast with Ghost, he has about 500 Movement Speed. I think like 502(o_O)?
*awkward silence*
Greater Quintessence of Knowledge. Like a boss!

Basically you want a blend of damage and survivability.

My first build is mainly damage, but I included the Hextech Gunblades for lifesteal, but mainly the 50% spell vamp. You're going to be healing for upwards of 700 with your Siphon of Destruction, 800 with Mace of Spades, 100~ a second for 8 seconds with Creeping Death, and pretty much your entire health bar with your ult. The AP is more than enough damage, giving you about 600 ap. You're going to whack them hard in the face with your AD too.

My second build is more on the tanky side. Force of Nature for MR and MS and crazy health regen, Mercury Treads, (which are not recommended because Morde likes Sorcerer's Shoes, he thinks that Mercs are ugly.) Sunfire Aegis, the universal tank item; Randuin's Omen, the other universal tank item, Abyssal Mask, wanted on AP Tanks, and a Rabadon's Deathcap simply for damage.

My third build is if you're SUPER FED. It's trololol, seeing as how you can Mace of Spades, Siphon of Destruction, and then ult them. For squishies (like Ashe), you can just follow the first two steps. Lich Bane proc + Mace of Spades will effing rape their faces and do like 1000+ damage. Let's calculate. MoS has about a 1:1.75 bonus ad ratio (I think, lol) and a 0.4 AP ratio. You'll have about ~500 AP. 200 bonus AD. Lich Bane will do 500. The AD ratio will do 200. The AP ratio will do 200. Base damage is 350. Siphon will still be of the same use. Now Creeping Death at this point is like stacking Sunfire Aegiss.

So your core items are:

That's it.

Your core items against a damage-heavy team are:

The last item can be damage if your roflstomping/facerolling them. Survivability if not.

Your core items against a tank-heavy team are:

Now the reason there are 7 is because Hextech Gunblade or Abyssal Scepter can be switched out for Zhonya's Hourglass. It gives armor, which you don't have there.

I can only think of a few, which are:
1: Rylai's Crystal Scepter for obvious CC which Morde does not have. Although the benefits are great, it's a bit costly for what it costs and I don't need the crowd control seeing I have a Hextech Gunblade active.
2: Thornmail if they have that Vayne/ Xin Zhao/ any other dps that's ripping you apart.
3: Deathfire Grasp. So, I've been debating whether to buy this or not. I've actually been doing pretty well with this item. "It gives mana regen, wasted stat noob." What? Yes, it is. But it gives like 10... so not much is being wasted. It gives some helpful AP, CDR, and the active isn't too shabby either. Nice percentage.
4: Mejai's Soulstealer. Obviously a risky snowball item. But with Morde, I can gain/keep stacks pretty well. So it's good if you're doing well early game. I usually buy this if I have like 5 kills early game, I don't trust stackers often.
5: Sunfire Aegis, adds to your Creeping Death for an extra 35 (not counting MR) damage. However, if they get any magic resist, even a Null-Magic Mantle, this item becomes useless.
6: Will of the Ancients, for an AP and spell vamp aura. Get it if your team is AP-heavy.

So you want to max your E out first, obviously because it does the most damage. "WTF Guidemaker Creeping Death duzthamostdmgnub."

Melee range damage ftw~

Siphon is your bread and butter. Max it first. This is the reason noobs cry "MORDE OP! NERF HIM!" while using an extremely squishy champion. It looks like very low damage, but it hits twice sometimes. So instead of 225, it can hit for 450. In fact, I've had it INSTAGIB an Ashe. From like half health. <3
Max Mace of Spades next if you're doing well, and Creeping Death if you're not. Why? Well Creeping Death gives you Armor/MR, as well as DPS. And Mace of Spades gives damage. It also resets your attack timer.
Obviously take your ult at 6,11, and 16. Like 99.9999999998% of people do that. (Looking at you Grassy! Seriously level up your ult...)

So.. your ult. You can use it two ways:
1:Offensively
2:Defensively

What can I say, many noobs use it on their opponent when the opponent is at full health, and I say NO! You suck. Because my teammates always easily get away due to his lack of cc. He might as well have thrown a pointy stick at Tristana. Use it on them when they are below 40% health with Ignite. Use it on them below 15% health without it.

Best people to ult:
All ranged carries that are NOT FEEDING. A fed one is great.

Still beneficial people to ult: all melee dps and fed ap carries.

Worst people to ult: Tanks. Unless you're dying, then ult them. The reason behind this is because tanks don't offer anything but a big meatshield, useable for taking towers, mostly. However, that Ashe ghost would be better, providing you with a ghost as well as a lot of damage.

Something that people really forget is that AP carries are not the worst people to ult. "Booooo downvote! Noob Mordekaiser!" Thanks. Anyways, look at it's description.

Children of the Grave. Mordekaiser curses an enemy, stealing a percent of their life initially and each second. If the target dies while the spell is active, their soul is enslaved and will follow Mordekaiser for 30 seconds.
Steals 24/29/34 (+0.04)% of target champion's maximum Health (half stolen initially and half over 10 seconds; deals Magic Damage).

If the target dies while cursed, their soul is enslaved and will follow Mordekaiser for 30 seconds. Mordekaiser GAINS 20% OF THEIR AP AND AD. The pet's stats are enhanced, gaining 15% of Mordekaiser's adjusted Attack Damage and Ability Power.

Pets can be controlled by holding the alt key and using the right mouse button.

Cost
No Cost
Range
850

Gains 20% of their AP/AD. I will usually ult that super fed Veigar instead of that feeding Vayne. Remember this~

And use it for defensive purposes. Use it on the tank, because odds are, he'll have the most health. Or.. if there's someone like a 3000 health Xin Zhao, use it on him. It will absorb more health because he'll have less MR.

1: Do not buy a Warmog's Armor. It's bad on him, because the health is redundant. His shield is already half of one. Armor/MR/Spell Vamp is a lot better. It has its places, like on an Olaf with it, a Frozen Mallet, and an Atma's Implaer. It doesn't work on Mordekaiser.
2: Do not auto attack the minions >_> I've noticed that a lot of people really love auto attacking those minions. Try to push back while getting as many minion kills as possible. At the same time, if they're actually decent players and only last hit, attempt to harass and last hit.
3: Do not build pure damage/pure tank. For obvious reasons. Pure damage gets killed in a second. Pure tank does no damage.
4: Do not hesitate to use Children of the Grave. Late game you should (if no one else really wants it) grab blue buff, because the CDR it gives is extremely helpful. If you get blue, your cooldowns will go down. A lot.
5: Don't hesitate to spam spells in the laning phase, your Regrowth Pendant will heal it right back.
6. Early game Rambo Mordekaiser. Lmao. Shield amounts to not much in early game, and you don't have your ult, AND no items.

You should not duo a lane with Mordekaiser. He needs the farm, and 1v1 is much better for him than 2v2. "But his skills are AoE!" Lol so? He gets focused down and first-blooded if he has an idiot lane partner (which, 80% of the time, you will), so it's not recommended.

Surprisingly, mid works for Morde. I rarely lose mid, even against some of the hardest/most annoying people . So it's great. Take mid IF YOU HAVE NO CARRY or you think your carry sucks. :P I cannot stress that enough. The person who goes mid should carry the game. You don't want to feed the other carry in mid, so if some cocky pub player asks for it and uses like, Anivia on a free week... SAY NO. Odds are, the person will fall several times.

So top lane is infamous Mordekaiser territory. Take it whenever you have a jungler/roamer. He loves farm. And it's your job to be like 2 lvls higher than mid, 4 lvls higher than side lanes. Explained later in the Common Solo Top Opponents section.

Creeping is what Morde does. He does the Creep (haaa) let's do the Creep (haaaa).
Anyways, he is one of the best last hitters of the game. Morde Es #1. Morde>Vlad.
Use this to your advantage. Try to last hit with SIPHON not regular attacks. Because 1: most enemies will push the lane; this will let you push back a little bit. And 2: because it's faster than auto-attacking. DO NOT auto-attack minions unless there's a huge wave. Doing so will leave your lane open to ganks.

Mordekaiser jungling? Nooob.
Lol yep. But mid game jungling is ok, he can kill neutral monsters easy. Early game jungling you say? Well here's a vid of Stonewall rocking Jungle Mordekaiser. (If you're interested, runes are armor pen red, armor yellow, any blue, and any quint.) Vid credits goes to Stonewall.
Play Video Only reason it's not viable is because the only tools he has for ganking is red buff. And because it goes 21-0-9... So it's AD Morde, which works, but isn't as good.

Scenario #1:
You're running away from a group of 5 with 700 health late game. How do you stay alive?

Ghost+ Force of Nature+ MS + Girly Scream of Life = 502 MS + luck.

Run like the wind, little girl! OMG KARTHUS ULT! Hit Alt+W to increase MR. "But it takes away health! You crazy?" Yes. Lol, no. It's minimal health, and it will help you survive.
Scenario #2:
2 people are coming to gank you, a Master Yi and an Ashe. Ashe fires her ult and hits you. What do you do? You run as fast as you can to the nearest bush. When they enter the bush, beat the Ashe to death, using Ult+Ignite combo. Then focus Yi with the ghost and yourself (Alt+Right-click to control ghost). ZOMG TRYN IS COMING!!! Ghost out, and if you're feeling extremely ballsy, run to the nearest enemy minion wave and charge up your shield while dealing damage to Tryndamere. Try to juke him out of his W, have your back turned and turn and face him, then run into a bush. He should be at 700 health, you're probably lower. Use E-W-auto attack-Q and he should be dead.
Scenario #3:
You're ganking a half-health Lux. How do you do so, considering you're lvl 7, and you have a feeding Xin Zhao assisting you?

Ping her and tell him to come from the front. You come from the back (she's near the outer turret) and Xin charges. However, he fails and gets E-R- tower shotted down like a noob. All up to you, she now has 1/3 health. Ghost in, E-Q-W-R-Ignite and dodge her snare. The reason you have to ignite is because she'd usually use her Prismatic Barrier and soak up damage. Ignite and your ult will kill her. Then push with her ghost.

Scenario #4: You are pushing top hard. You are 1v1ing against Cho'Gath and a lvl 4 Warwick comes out to kill you. You are lvl 6. What do you do?

There should be a bush on the left or right of you. Run into it. Kite Warwick around it, using Mace of Spades and Siphon of Destruction. When he's low enough, use Children of the Grave and Ignite. He should die by the DoTs. And Cho'Gath was afk to get food. ^_^ Ruuuuuuuuuuuuuunnnnn back to your tower, making sure to dodge Rupture. If you get hit by it, you're dead.
Spoils of War:
Mordekaiser:
Red and Blue Buff
Exp and 400 First Blood Gold
Confidence meter raised by 10!
Warwick will not gank you anymore.
Cho'Gath:
Rage bar increases by 100.
He gets reported.
His teammates rage at him, making him sad and troll his team.
Warwick:
Rage bar increases by 9001. Warwick ragequits. You easily win.

Play Video
Mordekaiser's favorite song. It has the name of his W ability. He likes his women like he likes his music, heavy* and metal*. Keep in mind, this is like a 7 minute song, so listen to it while you read. Go ahead and enjoy it,

While in Summoner's Rift (where I prefer playing Morde) he is viable in the right hands, on Twisted Treeline, he's downright OP. Tanky people are the new metagame. And at Twisted Treeline, that's where a lot of the squishies come to play :P Summoner's Rift is a lot more safe-feeling because you'll be near your turret. Twisted Treeline, you're in the middle, and there's like a foot's space between the middle and your turret. So that's just my thoughts. You can play him well on either map.

Jarvan IV
One of the hardest solo top opponents, with solid harass, tankiness, and last hitting only 2nd to yours. Counter? Focus on last hitting, but when there are no minions easily available, harass. Attempt to dodge Dragon Strike, too. It does very reliable damage, has a long range, a short cd, and is a part of his combo. Always keep your Iron Man up and go face the Demacian Lightshield Exemplar.

Rumble
An extremely annoying 1v1er, his Flamespitter will harass you enough to get through your Regrowth Pendant and then more. He will focus on harassing you 90% of the time, so harass back! Use your E on him and the minions; farm and harass simultaneously. Attack him when he's overheated, but in a kiting fashion.

Irelia
Not so much as hard as most, but many would turret dive her due to her being on low health a lot.

Don't. I can't tell you how many times someone has dived me when I was and I E-ed, Exhausted, and they died. Don't get greedy on her.

Brand, the Dutch word for fire. Hard IF you didn't get Quickness in the Utility tree ;D Dodge his Pillar of Fires easily. And if you have Greater Quintessence of Movement Speed it's extremely easy.
Summary: Dodge, farm, harass, farm, farm, dodge, farm, harass, harass, farm, farm, dodge, kill, first blood, push, win.

Katarina. The master of harassment. LOL, we have a shield so she's not a problem until lvl 6. And even then, just walk out of the radius.

Lee Sin, I see him in top sometimes. He just hits you with Q-Presses it again, W- to a minion. Does a lot of damage, like 150 damage at lvl 3. Lee Sin OP? It's a skill shot, hide behind your minions. An Ezreal like champion, easily countered, but the counter is easily forgotten/you never thought of it because it's so simple.

Morgana? Snare? It's OP? It does a lot of damage? It has an absurdly long range? It's for 2 seconds? It's craaaaaaaaaazy.
Wrong. Lol, it's so slow and easy to juke/dodge that it's sad. She's going to harass with Tormented Shadow instead. Which is STILL not going to do much. So she's easy. Just farm up. Her passive is going to give her a lot of sustainability, so don't harass her.

Nidalee. Ah, the infamous EU solo top. Too bad her spears are easily dodged. And her heal, while huge and spammable, is very costly. So she might've taken Clarity. If she does, don't bother to harass her, as she will heal, and heal and heal and then heal some more. Then she'll spear you... and heal.

You can't get any damage on their tower? And you can't get close to it? Just Siphon your way to victory here. Easy-cheesy-booby-squeezy. Minions will do a lot to the tower, actually.

Vladimir. This guy's annoying as chiz. Free Transfusion, healing himself while doing a lot of damage to you. Your best bet is to stop his farm. So zone him. And I'm not really going to post Shurelia's Zoning Guide because a lot of guides already have those, so.
Dare I say it?

Yes I dare.
Mordekaiser, yourself. Now this may happen to you. Wtf can you do to yourself? You'll have to wait. Odds are, he took a Regrowth and a health pot. Probably, the lane will be in the middle. So this is extremely even. Once you get to lvl 3, you can start farming/harassing. If he gets close to his minions, use your E. When you get to lvl 5, you can finally ACTUALLY harass him. Try for a first blood. Make his confidence drop down hard. He'll fear you. He might even entirely leave the lane and roam. I've actually had one ragequit :P Kill, kill, rage, kill, kill, rage, kill, kill, rage, harder rage, ragequit.

Same principles as top laning, but we can be more aggresive, because commonly there are 1v2 in top. Here are some more people you might lane against.

Ashe, very easy mid. Stay away from her Focus crit as long as possible, it'll hurt. Deny her farm by staying back a bit. So she'll have to decide whether to crit you or waste it on a minion.

Anivia, one of the hardest mids all right. She has her egg which makes her more durable than you would think. Flash Frost has insane damage, and Frostbite is the same. However, Flash Frost is extremely slow. So dodge it. Farm up, kill her, and gank a lane.

Annie, all she has is 2 AoE nukes, a spammable single target nuke, and a stun. Pssh. Simply avoid her stun. There will be a white ring thingy around her when it's up. Harass her more than she does to you. While, of course, farming.

Caitlyn, 2nd longest range in game (first being Tristana). Extremely good last hits, good harass with Piltover Peacemaker and Headshot. Charge your shield up as much as possible, we don't want to die.

Ezreal, King of mid? Nono. Prince of mid. For Mordekaiser is the king of everything! Dodge his Mystic Shots by staying behind minions. I once read in an Ezreal guide, "They think Ezreal is a fragile glass cannon. A tankier champ like Mordekaiser will take advantage of it and harass, push him back. What he doesn't know that we've got our runes and masteries set up for this. Get to lvl 2 and E-Q- Exhaust- Ignite-a few auto attacks and first blood." Don't get overconfident.

Karthus, by far the hardest mid in game. If you stay near minions, he gets farm and harasses you. If you stay away from minions, harass deals more damage. So you have to be constantly moving. Harass him a lot, too. Though he deals extremely high damage, he is one of the squishiest people in game.

Kennen, one of the few carries (like Ezreal) that, imo, get weaker late game. Meaning he has a very strong early game. So like usual, harass, farm, and all that stuff. Dodge Thundering Shuriken, he will follow up with Electrical Surge.

LeBlanc, also one of the hardest mids. She has insane damage starting at lvl 2 with her Sigil of Silence and Distortion, which means you could be zoned. Simple tip: stay as far from her as possible. Simpler tip: don't go mid :P

Malzahar, a Karthus-like mid. Stay away from the minions that have Malefic Visions on them because it could bounce to you. He will probably cast it on them when they're low, and auto attack the minions with it on them, resulting in you getting pushed. Odds are he took a Doran's Ring, a Meki Pendant and two Health Potion, or a Sapphire Crystal and two health pots. Harass depending on the situation. If he took that Doran's, harass him a lot, forcing him to go back and delaying his face lazer and his levels/farm.

Twisted Fate, like Ashe. But easier. Dodge Wild Cards because they have a huge spread, blah blah blah, avoid his Stacked Deck-Gold Card combo, and call when he has Destiny.

Tristana, one of the extreme WEAKEST people in early game. She has her Rocket Jump to get to safety, but for the most part, she has no resistance and not much damage.

Vayne, also epicly squishy. Tumble+ Silver Bolts+ Final Hour= Insane damage, though. Silver Bolts deals true damage, so health stack. At the same time, it deals a percentage of your max health. Your best bet is to have someone gank her early on, several times. Tumble is just an attack modifier, and Final Hour increases her AD by a huge amount, gives her stealth when Tumbling for 1.5 seconds, and gives her increased movement speed from her passive, Night Hunter. It QUADRUPLES it. Never run from Vayne if she is going in for the kill. Stand. And. Fight. If you run from her, she gets unpunished free hits onto you. Getting a Thornmail is advised against her.

These are just common people I see in mid. Ask me if you'd like to see someone I don't have here.

Ok. Forget all those heavy metal songs.
The Japanese songs are where it's AT!
No but seriously. Just listen to these intros :D

Skill #1: Mordekaiser is the only person with a huge, constant shield. (I think 630 at lvl 18. With Armor/MR, it goes a long way.) This is the reason I usually don't stack health/get a Warmog's Armor. When you have a lot of health, they classify you as the tank. They don't focus you. Most people won't click on you and look at your Armor and Magic Resist, but your health bar and (non-existent on Morde) mana bar and judge if they can kill you or not.
Skill #2: Morde has THE highest lifesteal in game with his ult, Children of the Grave. If he has like 6 Rabadon's (about 1200 ap) And you get 4% more max health with each 100 ap... well... that skill will do like 80, 90% of your health. Then he'll whack you. And you died.
Skill #3: He has 3 AoE skills. No one has 4. Some have 3. Like Vladimir and Brand, making him do well in teamfights. Compare him to someone like Alistar. Unbreakable Will is the ult that makes him a tank, as well as his base lvl 18 health. He has good CC, and one is an AoE! Well it's an extremely small AoE, easily missed. And the other one is a single target push back, which sucks.. because the person he Headbutt(ed) can just quickly get back in. The cooldowns are long, and the damage is low.

Most kills: 24/4, 24/3
Best ratios: 16/2, 22/3
Delayed-Penta and Quadra, each twice.
All the kills for my team: 18. I had 18 kills. Coincidence? (No I do not ks. In fact I get ksed.)
Beat this douche mid.
Most gold accumlated in a match: I thought 18,000. It wasn't ;D It was 24,000. 18,000 is an average late game.
Most assists: 28 (not much, but hey.)
8 turrets/inhibitors destroyed by solo-pushing.
312 minion kills by the end of a 30 minute game.
380 minion kills by the end of a 45 minute game.

So it's odd that I didn't think of this during the guide-making time. If you like my build, please Rep+ and upvote me.

So I hope that you will try to buy Mordekaiser. We'll see if you can go against me. Use this build, molding it. Use this guide. Take my castle and turn it into a palace. See what I did there? *raises eyebrows repeatedly*

No? Well ok D:

Now get out there and BUY MORDEKAISER!
