I got really bored and noticed a lack of TT oriented, or specifically stated build and strategy guides. I also want to share to the community why mordekaiser isn't op and describe my insane frustration over squishy champions on twisted treeline. Please note this is my first guide and I really don't like ranked matches, and most ranked matches wont even allow for Mordekaiser. Mordekaiser is a fun champ to play for the hell of it when you want to enjoy league of legends and play one of the more unique champions. So here it goes, this is how I like to play Morde =).

This is the obvious part. Just grab some magic penetration marks and the seals and glyphs are ability power. You could swap the Seals or Glyphs for Magic Resistance instead, it's really up to you. I prefer to have that extra kick early game.
I like my HP quints for survivability early and mid game. You could try magic penetration or ability power instead.

or + + + + = core build XD

This is the fun part.
My staring item is normally a Doran's Shield.
This is a great starting item: hp regen, armor, and health. What's not to like other than the fact that they reduced gold last winter so you cant get pots with that.
Depending on the enemies, I normally grab this and then go back after gank to get Health Potion or two, depending if I got kills. I might also be able to grab Boots too =).

Edit: After a few games, I have come to the realization that Regrowth Pendant is a very good start item as well and for the haters, if your enemy is not ad, go regrowth pendant. It's good against other mordes and mages. You can also bring a hp pot with your regrowth making it even better.

After I run out of pots, I go back to base and nab those boots, if I didn't already have them, Health Potion and Sight Ward. I normally stick with three Health Potions. If I have the cash, I get Sorcerer's Shoes. Note: Sorcerer's Shoes first, then Amplifying Tomb, Health Potion and lastly Sight Ward. I love sight wards, they really save you early game if you're on bottom.

Next, I enter the level six zone. You should have an insane minion count and a kill or two. Hopefully there are no deaths =). You should finish a Hextech Revolver and start building your Rylai's Crystal Scepter. Go for ability power first, then get the Giant's Belt.

Now you should be rat packing or pushing and finish a tower or get kills. Depends on the game. Normally I get a few kills on top and finish the tower before I start 'shredding'. With a Rylai's Crystal Scepter and Hextech Revolver you become a great damage dealer and probably wont need Health Potion. Therefore use your extra gold on Needlessly Large Rod or more wards.

If the game isn't over yet, the rest is conditional. Even Needlessly Large Rod is more of a luxury. If you get focused to much, build some defense. Generally tanks always build with three items: Chain Vest negatron cloack Giant's Belt. If you really need to, take the tank role and hope it's not to late to win. Else, finish the Rabadon's Deathcap and stack ability power (another Needlessly Large Rod, magic penetration Void Staff or cooldown reduction (don't normally need it so I don't know what to suggest).

I exclude the Frozen Mallet because I hope I have good cc on the team ( Dr. Mundo Xin Zhao Sion Singed Swain Anivia Nunu & Willump Amumu... need i go on for other great teammates?) Mordekaiser is an insane damage dealer and a bit tanky with his passive and rylai's scepter. Mejai's Soulstealer is nice, but you wont have time to build and stack it on twisted treeline unless you sacrifice the build and get it first. Then you become squishy and most focused. It requires stacks and an off game makes it extremely risky. Anything with ability power is almost always acceptable, unless there are mana bonus's involved (like Archangel's Staff).

Please don't tank with mordekaiser XD, but if you do, building tanks isn't hard. All you really need are three items ( Chain Vest Negatron Cloak Giant's Belt and build them into Thornmail/ Sunfire Aegis or quick silver sash/ Force of Nature or Warmog's Armor/ Frozen Mallet just cause frozen is nice on morde(hehehe), although I never really need to get one.

The Skill order:

: I love this passive, although it is easy to burst down. Remember, this doesn't make you invincible but definitely helps in laning and helps encourage ability spamming.

: The most useful skill and the one that will almost always be on cd. Great for farming and hitting/finishing champions in team fights and while they run. Good for getting that last minute damage to finish off that out of reach champ who thought got away. Also good for bush checks and just being a nusance. Just be careful early game, as without it you will die fast.

: I don't find this skill to useful. Its great for the armor and mr as well as pumping up your shield. However, I find the damage output not quite worth it and Mundo's is much better. However, late game it's nice for some extra damage and keeping shield up while you hit the tower/inhibitor/nexus. Normally I just ignore it. XD

: Another great ability. Towards mid game, you can use this and to take out a minions wave without doing any auto attacking. You can also use it to pump shield and harass enemy, but it's not like Siphon. I don't like it cause of it's limited range and Mordekaiser is slow. However it's nice for denying that annoyingly greedy Malphite next to you who keeps pushing minions and taking all the gold >(, I hate those Malphite when I don't get top.

: The greatest Ultimate ever. Just time it when the enemy champion has about 1/8-1/16 of their hp left. Then burst them down. It's also good for scaring the DPS out of a fight. It gives some life steal, but I barely notice it. Your ultimate guarantees kills in top lane at level 6, even against Vladimir(I actually love it when I get a Vlad, they're always so cocky and go down fast. Then they call you OP XD).

Solo Top:

This is the preferred choice. Mordekaiser can almost always guarantee a kill for almost every champion except possibly a good rumble player or someone who plays really defensively. This phase is simple. Last hit minions only to prevent pushing, watch for mia's and use Siphon of Destruction to last hit and power shield or just power shield to give you protection from life steal champs and harass those other champs.
Level two gives you Mace of Spades which lets you further last hit and harass melee champs and push champions away to deny experience when you target the caster minions. Generally I hit the minion next to the low health minion to deal extra damage and get some gold. If I miss, well hopefully I can get the minion traditionally.
Just keep leveling Siphon of Destruction and Mace of Spades till level six. Depending on the game, I'll generally have over 3-5 times the minion count of my opposing laning champion. I think it averages around 50 minions? I could be mistaken.
At level six you have you're ultimate. This is where mordekaiser kills. You can kill your enemy in lane or at tower. If their health is at half, it's very easy. If not, harass with Siphon of Destruction till he is. What you do now is dive him, Exhaust and Siphon of Destruction. Then pop your Ignite and Children of the Grave. If he's not dead, try to Siphon of Destruction or Mace of Spades. Normally he'll start running and a few seconds later I'll get a ghost.
Then you just push his tower. By the time he comes back, his tower is either dead or near dead. Go back to base, buy your items, come back, repeat and finish tower. That or just kill him again and finish that tower (hehehe my preferred method).
This finishes early game.
Mid game, just go run around and push the lanes, while killing/ganking the enemies. Wards are useful in this phase. Just stick together and push bottom lane. Be sure to maintain control of dragon and lizard. If you overextend and feel worried, just do a group jungle run. Hopefully you'll find one and get a ghost. Then you just push their base towers.
Late game: should almost never happen. If it does, then just keep pushing and try to get ghosts. If you get hit to much, buy some defense items. If it does get this late, that means bad team composition. Go find some friends XD. Remember, brusiers are godly on Twisted Treeline and any other champion except maybe tryndamre Nocturne Vayne are worth mentioning. Nocturne's late game will finish the game.

Bottom lane

I suggest you get friends. That and play super defensively. Last hit with [siphon of destruction]. With two champions, you're aggressive game play becomes deadly (not in a good way). Just ward and keep you're health up. Hopefully your teammate will do an early gank (be sure to ask). This will give you a level advantage to let you play aggressively. If you're low on health, don't be afraid to blue pill. Careful of stuns and crits.
Hopefully you get a non greedy tank on bottom ( Malphite Rammus Amumu but not greedy >( YOU LISTENING TANK PLAYERS?). That way you can at least harass effectively.
Often times, the top lane player forgets to farm top and I just kinda wander there and stay there for a few minutes. Don't forget there is always a jungle if you're minions are overextended. And try to help gank top if top overextends. (the next part is copy paste from top so if you read top no need to read, but do it anyway to engrave it in your brains XD)

Good Luck and Have Fun.
I won't talk about any champions much because I hope you have an idea of good TT champs. Brusiers with a balance of ability power and attack damage. Also a tank isn't ever a bad idea. CC is extremely effective so get a few stuns and slows please =).
Mordekaiser can take on almost any champion in the top lane, unless they play a fast squishy champ who kinda kites you and gets away with that 10 hp (grrr!) or stealth (you should have bought that vision ward instead of the Amplifying Tome. Oh and top Tryndamere is never an issue, as you should out level him easy (you should out level all champions on top lane).

Mordekaiser is a fun champion for a relaxing normal game. I'm that guy that wants 700 wins without a single ranked match and plays a champion for 2 months before trying another XD. Don't get to cocky and don't flame and have fun. Play safe and grab some friends. Twisted treeline is all about team composition, rather than a good caster, tank, and attack damage champion. It's also good to double up on roles and only use brusiers. These are my twisted treeline tips. Yes there are only a few good champions on twisted treeline, but most champions are conditional. Communication is key on a small map, so get on skype and talk. There is no need for any real mobility spells or buffs, except the wraiths, since it's free =). Remember, this is my build to him, and some people like the Rylai's Crystal Scepter + Frozen Mallet combo. I don't, not enough damage potential and I don't normally need CC. The hextech helps early/mid game and makes you tanky late game. Please comment, give me suggestions and don't hurt me >.> it's only my first guide =)
